Data Lake Files physical storage and Object Store in Datasphere & BDC context

2025-12-27T17:52:56.191000+01:00

Greetings SAP experts!

For some time I am trying to understand some concepts in regards to the Object Store and Data Lake Files physical storage in Datasphere & BDC context.

First I will start with naming the main service components of the SAP HANA Cloud that you can subscribe in SAP BTP:

SAP HANA Cloud, SAP HANA database
SAP HANA Cloud, Data Lake further formed from:
- Data Lake Files
- Data Lake Relational Engine

https://help.sap.com/docs/hana-cloud/sap-hana-cloud-getting-started-guide/sap-hana-cloud-components

Now let's start with SAP Datasphere

When we have a Customer Managed Space:

With Storage Type SAP HANA Database (Disk and In-Memory) -> I believe physical storage will be in SAP HANA Cloud, SAP HANA database on which the Datasphere tenant itself relies on.

When it comes to Storage Type SAP HANA Data Lake Files:
- Where are the Data Lake Files behind the Local Table(file) physically stored?
  - In the Object Store?
    - If yes - What kind of Object Store is used?
      - SAP Managed Object Store (File Container)?
      - External Object Store (Azure Blob Storage / Azure Data Lake, AWS S3 bucket, Google Cloud Storage bucket)
  - In the SAP HANA Cloud, Data Lake Files (service component) of the SAP HAHA Cloud underlying SAP Datasphere tenant?

Further, in BDC context.

Let's say we activated a Data Package from BDC Cockpit, APRS starts pushing data to target HANA Data Lake Files i.e. SAP BDC Foundational services (FOS) layer.
- Again, where are these Data Lake Files physically stored?

https://help.sap.com/docs/object-store/object-store-service-on-sap-btp/what-is-object-store

Really appreciate any input helping me to clarify these topics.

Kind regards!

EF Core 9 migrations fail with SAP HANA provider due to missing IMigrationsDatabaseLock support

2025-12-30T14:59:21.442000+01:00

Hi everyone,

We are using SAP HANA Cloud (service type: schema) from an ASP.NET Core application with Entity Framework Core 9 and the Sap.EntityFrameworkCore.Hana provider.

We are facing a blocking issue when using EF Core migrations.

Problem description

When executing migrations (for example, by calling Database.Migrate() during application startup), EF Core throws the following exception:

System.NotSupportedException:
Generating idempotent scripts for migrations is not currently supported for SQLite

The exception occurs in the following method:

IMigrationsDatabaseLock AcquireDatabaseLock()

Important clarification

We were previously using EF Core 6, where migrations worked by generating SQL scripts manually.

The application is correctly connected to SAP HANA Cloud and works properly as long as migrations are not executed.

We are not using SQLite; the error appears to be caused by internal reuse of SQLite migration infrastructure in the HANA provider.

Impact

This makes EF Core migrations unusable with SAP HANA, even when:

Using SAP HANA Cloud
Using schema-based services
Having full DDL permissions

As a result, migrations cannot be applied.

Request / Question

Is there any plan to:

Properly implement IMigrationsDatabaseLock for SAP HANA?
Remove or replace the SQLite-based fallback in the HANA EF Core provider?
Officially support EF Core 9 migrations, even if only partially (as was possible with version 6)?

At the moment, EF Core + HANA can only be safely used as an ORM, not as a schema management tool.

Any guidance, roadmap, or official recommendation would be highly appreciated.

Thanks in advance.

Relationship on HANA Cloud Max Connections and CAP DB Connection Pools

2025-12-30T18:16:21.482000+01:00

Hello,
When two HDI containers that reference the same HANA Cloud instance are used by applications A and B respectively,
if the sum of the DB connections configured in applications A and B exceeds the maximum number of connections internally configured in HANA Cloud (which, as I understand, is SAP-managed and cannot be changed arbitrarily by customers),
could connection timeouts occur?

I expect that this could happen, but I would appreciate hearing others’ opinions, experiences, and any advice on possible solutions.

"Unauthorized" error message - Find Data Sources for Calculation View

2025-12-31T18:25:36.903000+01:00

Hi Experts.

I am working on a simple CAP application were I need to create a Calculation View ( .hdbcalculationview artifact) and when I browse the possible available tables for a Join or a Projection the "Unauthorized" error message appears (see the attached images).

The SAP Hana Cloud is setup via Cloud Central tools and is mapped and running in Cloud Foundry.

Do you know if is due a missing role or something else (HRTT API, SAPID, packages versions, other)?

Thanks in advance for your support

Is there any standard way to achieve manage global hierarchies in SAP S4 Hana Cloud

2026-01-06T19:24:30.439000+01:00

Hi Team,

The current implementation of two global hierarchies in the SAPUI5 Fiori app, bound to a tree table, requires four API calls per hierarchy. Scaling this to 12 hierarchies would necessitate 48 API calls, leading to significant performance degradation, data latency, and potential application crashes. Consequently, utilizing a custom ui5 Fiori app for retrieving multiple hierarchies is inefficient. Additionally, for every hierarchy in 4 th API call - need to aggregate the amount if id is unique. So multiple unique ids present applicable for all hierarchies, So achieving global hierarchy in SBS is not a good option with multiple api calls and data calculation in every 4 th api call and data wil be millions in production.

I suggested that the client, SBS fiori app is not a good option to achieve this requirement by calling APIS 48 times, every hierarchy we need to check repeated ids and calculate the total amount for unique id in the back end.

Also fiori app will use for limited data set. Not like million records calculations in the backend .

Question : -

We are trying to build a GL Line Item report that has the functionality to display the report in "multiple global hierarchies" such as profit center, cost center and GL Account (total 12 multiple global hierarchies) in the same report. Side by side application has limitations, we want to know if there is a standard functionality to achieve this.

Thanks,

Madhava

Hello,

I'm looking for a solution to get an email when a scheduled HANA job failed. By HANA job, I mean the one created with the artifact hdbschedulerjob.

Currently we use side applications to schedule the flowgraphs and get an email in case of error but I would prefer a native HANA+ANS solution.

Best regards,

HANA Cloud: Inconsistent Network Egress Consumption

2026-01-23T16:22:52.964000+01:00

Hello Everyone,

First, here's some context: we're making use of BTP with the Cloud Foundry Runtime with AWS as our backing hyperscaler and our primary persistence layer is HANA Cloud.

For the problem: Towards the end of 2025, we noticed some peculiar behavior with regards to network egress in our HANA Cloud instance. We had a very stable level of network egress consumption between January and September 2025 but in October and November we saw this consumption nearly double before receding to more baseline levels in December.

There are two problems with these changes in consumption levels:

We had no discernable code changes that correlate to the increases beginning in October OR the decrease that began in December
December is by far our highest volume month in terms of database use which is inconsistent with it returning to normal levels of network egress consumption

While this was initially discovered by looking at global account level consumption statistics, it was confirmed within the HANA Cloud dashboards themselves AND the metering and metrics APIs (as described here: Metering Metrics).

Our leading theory into why we see these random jumps is due to how Availability Zones (AZs) are handled within BTP. HANA Cloud instances very clearly have an AZ visible in HANA Cloud Central. In our particular case that zone is us-east-1b.

App instances are another case entirely though. SAP has published a note on the question (3476931 - Is it possible to get Availability Zone for BTP Cloud Foundry application?) which states the following as its resolution:

SAP controls the AZ of Cloud Foundry applications to ensure availability. It is not necessary/needed that customers know/manage the AZ for custom applications.

This clearly indicates the actual AZ of app instances is out of control of customers. This reveals a potential problem though given that the underlying hyperscaler AWS charges for network traffic between distinct AZs in the same region. If we take these facts together:

HANA Cloud is deployed in a particular AZ
App instances are deployed in AZs under the control of SAP
AWS charges for network data transfers across AZs

That would indicate that customers are open to seemingly random increases in network egress consumption based on how app instances are deployed and they have no means of controlling that.

Now, there is a note (3443501 - HANA Cloud overage costs) that states managing network consumption is not SAP's responsibility, but given what we know about AZs, this seems customers lack the tools to adequately manage these costs.

The question: Given what we know, has anyone else experienced similar issues and how did you get this type of consumption under control? We really seem to be at a loss for this and these increases in consumption are non-trivial.

I appreciate any insights on the matter.

Thanks,

Brian

Event based Revenue Recognition for service dokuments 3M3

2026-01-30T09:45:38.452000+01:00

Hello dear proffessionals,

we use the 3M3 for service Documents. The customer wants to change the correction account into the revenue account of origin, in order to have a better overview, when the posting is done after a run.

So like....Revenue Account is 40000009 then for correction the system should take the same account to book the accruals against.

Where can we maintain this change in the System?

Thank you in advance.

how to reverse the client copy

2026-02-12T08:39:49.969000+01:00

Hello experts,

I would like to ask how to reverse the client copy action? I used transaction code SCC9N to perform a remote client copy with the profile SAP_CUST. Originally, I only wanted to overwrite the configuration from the production environment to the test environment, but I didn’t expect it to clear all the business data in the test environment. Is there any way to restore it?

App "Manage Purchase orders" print view is not shown - Message: form template not found

2026-02-18T13:00:01.859000+01:00

Hi,
I’ve created a line item in the "Manage Purchase Orders" app using a cost center (no material master). To be precise, I’m facing an issue with the print preview.

The Problem: I cannot see the print preview before saving the PO when logged in in German. However, the preview works perfectly when the login language is English.

When attempting the preview in German, I receive the following pop-up messages:

Following message is being shown after I choose the preview above:

In Transaction OPD: Output Parameter Determination: Here is the current configuration for the output parameters:

This is the second part of the same picture above of the output parameter determination

Why is the preview failing specifically for the German login? Does this relate to the cost center assignment (which means for materials withoud master data) or a language-specific setting in the output determination?
Thank you for any relevant information.

Clarification on SAP S/4HANA APIs for Customer, Billing, and Financial History Integration

2026-02-19T09:55:38.540000+01:00

Hi Experts,

I am currently working on integrating an external web application with SAP S/4HANA and would appreciate some guidance on selecting the appropriate APIs/services.

Application Context:
My application functions as a customer management portal. In the existing system (Oracle-based), we display and manage:

Customer data
Bill / Invoice details
Bill / Invoice history
Financial account (FA) history
To-Do management (Add / Update / Delete operations)

We now need to implement similar functionality using SAP S/4HANA.

Clarifications Needed:

Customer Data
Which APIs are recommended for retrieving and managing customer master data?
Billing / Invoice Details
Which standard APIs should be used to fetch:
- Invoice / billing details
- Invoice history / open items
Financial Account / History
For financial/account-related history (balances, transactions, etc.), which APIs or services are appropriate?
CRUD Operations
For operations such as Add / Update / Delete (e.g., To-Dos or related entities), should we rely on:
- Standard OData APIs
- CDS-based services
- Custom APIs
Best Practice Approach
From an architectural perspective, what is the recommended approach:
- Standard SAP APIs (API Hub)
- Custom CDS Views + OData
- RAP / BTP-based services

Any pointers to relevant APIs, documentation, or best practices would be greatly appreciated.

Thanks in advance for your support.

Best regards,
Kavinkumar

Hello Guys!

I am developing in the Business application studio for quite some time Hana CDS views and I have started to generate Odata Services.

I know what is the url of the main branch for testing the odata service but right now If I want to test an Odata Service I have to merge back my development into the main branch to test it out.

My questions is how to the get URL for the service that exists in my own development hana container.
I would like to test my services before merging but this is impossible I have know clue where to look for the URL

Unable to Update Data in Custom External S/4HANA OData Service (SSAM2405)

2026-02-26T10:40:31.511000+01:00

Hello Experts,

We are trying to integrate an additional external S/4HANA OData service (our own custom service) into the standard SAP Service and Asset Manager (SSAM) 2405 application.

Steps we followed:

Created a destination in SAP Mobile Services for our external S/4HANA service.

2. Added the service to the standard SSAM metadata by creating a new service in the Z component

3. After synchronization, the service metadata was generated successfully (XML created without errors)

4. We are able to read data from the backend service successfully in the application

Issue:

When we try to update data from the Edit page, the Save action triggers the OData Update action, but the data is not updated. We are receiving an Internal Server Error.

In the backend traces, only GET requests are being triggered. There are no POST or PUT requests being sent during the update operation.

Question:

Is it supported to use a custom external S/4HANA OData service within the standard SSAM metadata?

If yes:

Are there any additional configuration steps required to update the data? Have we missed anything?

Any guidance would be greatly appreciated.
Thank you in advance.

Best regards,
Kingston A.
