SAP instance fails to start when SNC (Kerberos) is enabled

2026-01-23T13:36:07.546000+01:00

Hello

when we try to start SAP, it does not come up

SAP instance fails to start when SNC (Kerberos) is enabled – work processes abort during SNC initialization

System / Environment

SAP NetWeaver AS ABAP

OSS: Linux (RHEL 9)

Database: Oracle 19c

SNC configured with Kerberos (MIT Kerberos, GSS-API)

snc/gssapi_lib set to /usr/lib64/libgssapi_krb5.so

snc/identity/as configured with machine principal

The SAP ABAP instance fails to start when SNC is enabled.

The startup stops during work process initialization.

When SNC parameters are disabled, the SAP system starts successfully.

Observed Behavior

SAP instance startup proceeds normally:

DIspatcher starts

Database connection succeeds

Work processes are spawned

During work process startup, SNC initialization begins.

The SNC library is successfully loaded:

SncInit(): found snc/gssapi_lib=/usr/lib64/libgssapi_krb5.so

File "/usr/lib64/libgssapi_krb5.so" dynamically loaded as GSS-API v2 library.

Immediately after loading the GSS-API library, the work process terminates with signal 6 (SIGABRT).

This behavior repeats for multiple work processes, causing the instance to fail startup

SncInit(): Initializing Secure Network Communication (SNC)

SncInit(): found snc/gssapi_lib=/usr/lib64/libgssapi_krb5.so

File "/usr/lib64/libgssapi_krb5.so" dynamically loaded as GSS-API v2 library.

/usr/lib64/libc.so.6(abort+0xd3)

...

/oracle/SID/19/lib/libclntsh.so.11.1(krb5int_key_register+0xb1)

/oracle/SID/19/lib/libclntsh.so.11.1(gss_krb5int_lib_init+0x29)

...

SncPDLInit()

SncInit()

ThSncInit()

ThInit()

abort()

System remains unavailable

Disabling SNC (snc/enable = 0) allows the system to start normally

Although SAP loads the configured GSS-API library successfully, the stack trace shows that Kerberos-related functions are being executed from the Oracle client library (libclntsh.so) at the time of the abort.

QUESTIONS??

Why SAP work processes abort during SNC initialization after successfully loading the configured GSS-API library

How SAP expects SNC / Kerberos to behave when Oracle client libraries are present in the same process

Any known SAP Notes, restrictions, or supported configurations for:

SNC (Kerberos)

Oracle 19c client

Exporting PIRs from MD62/MD63 to Exce

2026-01-27T14:55:14.342000+01:00

Hi experts,

I’m trying to export the PIRs from MD62/MD63 to an Excel file, but I haven’t found a way to do it yet. I have already tried using transaction MD79, but the issue is that it only allows exporting one material at a time. There’s no option to select multiple materials or an entire product family.

Is there a way to export all PIRs at once to Excel?

Thank you in advance for your help!

How to prevent additional Planned Orders when stock covers >90% of requirements? (Dynamic Rounding)

2026-01-29T07:53:15.336000+01:00

Hi experts,
I am facing an issue with over-planning for semi-finished goods (HAL1).

[Current Situation]
When a production order is partially confirmed or "prepped" stock is slightly lower than the original planned quantity, MRP immediately generates a new small-quantity Planned Order to cover the minor deficit.
However, in our business process, if the available stock covers more than 90% of the requirement, we do not want to trigger additional production.

[Requirement]
I want to set a tolerance/threshold where MRP ignores deficits smaller than 10% of the total requirement.
• Example: If Requirement = 100 and Stock = 92 (8 deficit), No new Planned Order should be created.
• Example: If Requirement = 100 and Stock = 85 (15 deficit), Yes, a new Planned Order should be created.

Inquiry Regarding Custom Tax Engine Integration and TDT Support in SAP S/4HANA Cloud, Private

2026-01-30T01:39:30.925000+01:00

1. Background Our client is a global enterprise operating in over 100 countries. We have developed a proprietary in-house Tax Engine.

B2C Business: Tax calculation is handled at the front-end sales system by calling the Tax Engine directly.
B2B Business: We plan to trigger the Tax Engine within SAP S/4HANA Cloud, Private Edition to complete tax calculations for Sales Orders (SO).

2. Key Concerns & Limitations The client is concerned that the standard SAP tax configuration may not support their complex global requirements due to:

a. Tax Code Constraints: Standard tax codes (2 characters) have a 1-to-1 mapping with tax types/rates. Managing validity periods at the tax code level is restrictive (validation issues), making it difficult to handle multi-tax/multi-rate scenarios across 100+ countries.
b. Granularity: Difficulty in accommodating highly granular tax management and business classification requirements.

3. Evaluated Integration Approaches

Approach A (External Suite Model): Similar to Thomson Reuters/ONESOURCE. Using custom programs to sync MM/SD/FI document data to the Tax Engine and returning results to SAP via dynamic condition records.
Approach B (India GST Model): Leveraging a framework similar to the 2017 India GST solution. We need SAP to detail this architecture and any potential business/product limitations.

4. Specific Questions on TDT (Time-Dependent Taxes) We understand that TDT is primarily available in SAP S/4HANA Cloud.

Does the Private Edition fully support TDT for all 100+ target countries?
Can TDT resolve the aforementioned limitations regarding tax code exhaustion and validity date validation in a global rollout?

5. Request for Guidance

Could SAP provide architectural best practices for integrating a 3rd-party tax engine in a Private Edition environment?
Which approach (A, B, or a modern API-based service like SAP BTP Tax Service) is recommended for a global enterprise of this scale?

Does cal.sap.com run in SAP's corporate AWS acount?

2026-01-30T22:46:45.840000+01:00

Hi, We will be setting up a trial device on AWS, and our internal Security Team is asking if the website cal.sap.com is hosted in an AWS account. If so, they have requested SAP’s AWS account number. If it is not hosted in AWS, a simple confirmation of that will do.

Thank you!

MD79 ISSUE "XXL has not been installed correctly!"

2026-02-02T10:37:58.450000+01:00

Hi Expert,

I am facing an issue when running transaction MD79 via Fiori.

When I execute MD79 in SAP GUI, it works correctly and the Excel export for PIRs is generated without any issue. However, when I run the same transaction via Fiori, I receive this error message during the export "XXL has not been installed correctly!"

Do you have any idea what could be causing this issue and how it can be resolved?

Thank you in advance for your support.

Sequence in which QA10 transaction (RQEVAI30) picks the inspection lots for processing

2026-02-04T13:42:48.852000+01:00

Dear Gurus,

We came across an issue where the QA10 program which ran via batch job daily picked two inspection lots and posted UD however, it picked the latest inspection lot first and then the older one.

The scenario is like, 1st a manual inspection lot was created for material/batch to record results of some MICs however, the business entered wrong values and decided to create a new inspection lot for the same material/batch combination. Now, there are two inspection lots for material/batch but with two different values in MIC. Once the batch job for QA10 ran, it updated the batch characteristics from the 1st manual inspection lot. This created a panic within users, and they reached out to us.

Upon checking the logs in QA10L, it showed that - the QA10 program picked the 2nd lot first for posting UD and then the 1st lot. So, the value of MIC from 1st lot was updated in batch characteristics.

So, wanted to know how does the program picks lots for processing auto UD and is there a way to make it pick in sequence of lot creation.

Thanks a lot, in advance.

Best Regards,

Omm

Vendor selection in third-party process

2026-02-06T14:27:55.163000+01:00

Hi everyone,
I'm struggling with this problem during the third-party process.
When we make a sales order, we change the item category in ZTAS. That is the correct value for this process.
For material Z1, we can have two vendors.
The source list is maintained for vendor A and B, and A (EU vendor) is defined as fixed, while the second, B (non-EU), is not fixed. The info record is maintained also.
When we create a sales order for a specific customer , we would like the system to always select vendor B instead of A for the PR, as it is closer to the customer.
We can change the vendor manually , sure, but if the sales order has more than 200 lines, it is a very big effort.
Is there any workaround to achieve this scope without an ABAP program?

S/4 Hana - Track on SO schedule line level both requested delivery date and committed delivery date

2026-02-12T08:57:29.491000+01:00

Hello,

I am working for a Make to Order scenario project, my customer wants to trace in the sales order just for statistical purpose at schedule line level both the initial requested delivery date of the customer and also the committed date (if the date requested by the customer is not feasible).

In the sales order there is not availability check and are not configured lead times; the Customer care should enter manually the requested delivery date for each sales order item (also eventually splitting quantity on different dates), then if after discussion with Planning the date is not feasible the Customer care will enter for each schedule line previously defined the committed date (the date on which the company commits to the customer to deliver the product).

There is any standard solution to satisfy this requirement? Otherwise I am thinking to add a new custom field "committed date" on schedule line tab of the sales order.

Thanks in advance for your help.

Changing Stock Status from Quality Inspection to Unrestricted

2026-02-12T09:55:29.809000+01:00

I would like to inquire about a specific issue regarding stock status. Currently, our inventory is in "Quality Inspection" status, but there is no corresponding quality inspection lot available, which prevents us from using transaction QA32.

We need to change the stock status from "Quality Inspection" to "Unrestricted." Could you please advise on the steps required to transfer this inventory to an unrestricted status?

We attempted to use MIGO to perform a 321 inspection in order to change the stock status to Unrestricted, but we encountered an error message stating, "You can only change the inspection stock for material XXXXXXX in Quality Management.(只有在品質管理中更改物料XXXXXXXXXX檢驗庫存)"

Multiple issue delivery outputs

2026-02-18T15:10:14.076000+01:00

Dear SAP Gurus,

On the VL03N initial screen, after I type in the outbound delivery number, I click "Outbound Delivery", then "Issue Delivery output", "Print preview" and the system generates a file that I can save or print. We use this process to generate "Delivery acceptance protocols" for deliveries of our goods.

My question is - is there any way to generate such files/protocols for multiple outbound deliveries at once so I don't have to go through the full process for every single delivery.

Thank you in advance!
