Synchronous RFC call not receiving response data form PI/PO middleware

2024-03-08T07:04:13.581000+01:00

Hi Member's,

I am able to send the data successfully to PI/PO system through RFC call & from PI/PO system it is showing it has pushed the response data to ECC successfully . But in calling program I am not receiving any response instead the data which I am passing through RFC (VATPOSTINGS ) is also getting cleared.

Request :RFC call from ECC => PI/PO => external system (No issue , everything works as excepted )

Response : external system => PI/PO => ECC ( Response from PI/PO not received in calling program )

Not able to figure out for what reason I am not receiving the response, Please let me know if there is any thing I have to handle additionally.

RFC_CALL_TRANSACTION_USING

2024-03-08T12:15:10.830000+01:00

Hello together

Use case:
I call the module RFC_CALL_TRANSACTION_USING from my external application via RFC.
I would like to call the transaction "IE03" and display it in the GUI.
I also transfer the equipment no.

Result:
The GUI window opens in the transaction with the correct equipment

Problem:
The GUI window can no longer be closed until I close my external application.

Code:

public void CALLTRANSACTION(string TCode, string EQNr)
{

// Rufe die SAP Einstellungen auf
var sapDestination = sapConnector.GetDestination2();

// Funktionsbaustein aufrufen
var function_Transaction_Call = sapDestination.Repository.CreateFunction("RFC_CALL_TRANSACTION_USING");

// Setze die Parameter des Funktionsbausteins
function_Transaction_Call.SetValue("TCODE", TCode);
function_Transaction_Call.SetValue("MODE", "E");

// Struktur vorbereiten
var BT_DATA = function_Transaction_Call.GetTable("BT_DATA");

BT_DATA.Clear();
BT_DATA.Append();

BT_DATA.SetValue("PROGRAM", "SAPMIEQ0");
BT_DATA.SetValue("DYNPRO", "0100");
BT_DATA.SetValue("DYNBEGIN", "X");

BT_DATA.Append();

BT_DATA.SetValue("FNAM", "BDC_CURSOR");
BT_DATA.SetValue("FVAL", "RM63E-EQUNR");

BT_DATA.Append();

BT_DATA.SetValue("FNAM", "BDC_OKCODE");
BT_DATA.SetValue("FVAL", "/00");

BT_DATA.Append();

BT_DATA.SetValue("FNAM", "RM63E-EQUNR");
BT_DATA.SetValue("FVAL", EQNr);

function_Transaction_Call.Invoke(sapDestination);

}

Update Exchange rate from BCE.

2024-03-14T10:33:03.215000+01:00

Starting from today (14/03/2024) when I download exchange rate from www.ecb.europa.eu:443 with report RFIMPNBS I receive this error message:

SSL handshake with www.ecb.europa.eu:443 failed:

SSSLERR_ALERT_HANDSHAKE_FAILURE (-122)#Peer aborted TLS handshake with fatal TLS handshake_failure(40).

All certificate in STRUST are correct.

Is something changed in www.ecb.europa.eu?

There are others SAP users with same problem?

Thanks

Regarding RFC destination 'NONE' and RFC context

2024-03-17T04:04:35.392000+01:00

Hi experts,

Sometimes I can see RFC destination 'NONE', the RFC call is in the current system but in an RFC context.

I have checked the help doc regarding RFC context.

https://help.sap.com/docs/SAP_NETWEAVER_700/108f625f6c53101491e88dc4cf51a6cc/7509c2df49a44c4e9aee12986cffccb4.html

But I'm not clear about the difference between if data is in RFC context or not. Could someone help to explain more on that? e.g., LUW.

Ming

'INTO' is invalid (due to grammar) error while SQL in BAPI

2024-03-17T06:34:13.295000+01:00

Hi guys!

The error occurs in the first INTO of the first SELECT. I have 'INTO' is invalid (due to grammar)
I need to return several tables that will become arrays in an application that will call this BAPI remotely (RFC). However, when I add this code to the SAP that will run the RFC, it gives a problem with the INTO clause.
INTO is invalid here (due to grammar), but I don't know what I'm doing wrong, because I've already run this function in other SAPs and it worked normally.
The logic of this RFC is to return the data from the MARD, MARC, MAKT and MBEW tables based on the MARA table. Then I perform a select with where in the MARA table that will return a series of items, and based on the code of these items I perform a FOR ALL ENTRIES to search for these same materials in other tables and return them separately. I can't use joins. And then I come across the INTO clause error when I use anything between the word MARA (FROM MARA) and INTO. (In this case it's the order by)
I need the up to to be able to limit the lines of this return.
Can anyone help me?

How sending data through RFC using register sever program ID work?and handler was not installed erro

2024-03-17T21:40:45.652000+01:00

Hi, I'm currently working on sending and receiving data through RFC between SAP to Non-SAP,
and having difficulty understanding how Registered Server Program work.

Here are 2 RFC s they require. .

A .Sap Receive data (data is sent from non-SAP to SAP. data is saved in SAP after receiving data)

B .Sap Send data&receive result (data is sent from SAP to non-SAP and non-SAP will send back result Sucess/Fail to SAP)

A RFC is simply done by RFC being called on non-sap part.

For B RFC, I thought it'd be done same that they will call by using connector, But they require SAP Program to directly send(push) data so taht they will return the result back to SAP.

I asked them how theyll fetch data, and their reqmt was SAP to Create RFC desitnation and Registered Server Program.

So now, RFC Destiantion 'ZTEST' is type TCP/IP created which contains Program ID is 'ZTEST' as registered Server Program n SM59, and the connection test is success .

In the program for sending data..

call function 'ZTEST_RFC_EXPORT'

DESTINATION ZTEST

TABLES . ..

but it's returning short dump for "handler for ZTEST_RFC_EXPORT was not installed

I need help how sending data through RFC work just by registerng registered server program work.. whether it is correct step to send & get return data from non-sap system , and if it is why this dump is returning.

pyRFC license and cross license

2024-03-31T07:48:55.110000+02:00

Hi,

I am using pyRFC for my development. I found it is under licensed under Apache 2.0. *https://github.com/SAP/PyRFC/blob/main/LICENSE As mentioned there, I can use it for commercial purpose to interact with SAP data from python application and vice-a-versa.

Our customers already have SAP ECC/ S4 HANA required licenses.

However, I wonder fetching data or sending data to SAP would add cross licensing cost or not. Any experts in this group who can guide me in this issue?

Thanks,

SAP Exception while calling RFC from .NET MVC Framework.

2024-04-11T07:43:50.342000+02:00

I'm using the .NET MVC Framework (v 4.8) to call an RFC function of SAP using RfcDestinationManager from sap.middleware.connector (sapnco.dll and sapnco_util.dll).

The website is hosted on an IIS server with a .NET CLR Version of v4.0.

The issue I'm encountering arises when I call the RFC with the parameter FunctionalLocationID to retrieve SAP notification numbers. While it operates smoothly approximately 80% of the time, occasionally it crashes within the IIS server. Interestingly, there are no exceptions in the code, nor any error traces on the SAP side. The only indication of the issue appears in the Event Viewer of the hosting server.

Code

Below, I've attached screenshots of the encountered errors for further examination.

RFC registered program

2024-04-17T10:10:49.603000+02:00

Dear all,

We have an RFC destination with a gateway registered program which belong to an external server/application.

So, if that external server change the IP address, do we have to re-register the program with rfcexec in our gateway again or SAP will update the IP address and details using the hostname we provided ?

Remote RFC Call conversion error <INVALID>

2024-04-29T11:07:29.148000+02:00

Hi,

some of our custom remote called Function Modules are receiving corrupt data when executed.

The passed Parameters to the Function Module are created dynamically from the expected Types of the calling System, so there should be no Problem in diffferent types or lengths.

How to reproduce:
When the Program jumps into the called System, '#' is simply inserted in some of the formerly empty fields, which shifts the whole passed Structure and then <***INVALID***> appears on other Fields.

Environnement:

The calling System is a Unicode SRM System. Caller System is a S4 System. Codepage in SRM is 4102, enforcing this Codepage in SM59 did not resolve the issue.

RFC user and permissions

2024-05-09T09:25:31.966000+02:00

Hi all! SAP ERP total newbie here,

I wanna make some RFC calls from VBA and power automate (using SAP ERP connector) and I would like to know which type of user should I create in SAP (I assume technical one, not dialog) as well as the roles required for making RFC and BAPI calls. I would like the authentication to be via SAP Authentication (i.e. username and password)

Thanks!

Uploading Business Partners as vendors within the SAP system.

Extracting Large Table Data from SAP ECC / S4H

2024-05-14T09:05:47.091000+02:00

Are there any recommended methods for extracting large table data from ECC / S4H via a remote connection?

Function Module RFC_READ_TABLE is available but not release for customer use and therefore not recommended. What would be a suitable alternative (SAP, custom, or 3rd party) for extracting large tables (million+ records)?

My understanding is that CDS views are also not recommended for extracting large volumes of table data?

SAP NCO 2.0 RFC_READ_TABLE returns empty RfcAbapException

2024-05-14T14:06:57.240000+02:00

Hi all,

I have a very weird situation here, on the customer side one of the tables just stopped return data when we do read it by RFC_READ_TABLE. The table is V_IBIN_SYVAL, what we are doing is just retrieve ATINN values from the table by IN_RECNO ids. So where statement is super simple like IN_RECNO IN ( 051MWa057jQxnYf9m1oEBm, 051MWa057jQxnYhfQYAEBm, 051MWa057jQxnYilPcUEBm, 051MWa057jQxnYymFixEG0, 051MWa057jQxnY{HReCEG0 )
We also do split by separate options to meet 512 max symbols requirement.

The most interesting is I tried to execute a query without specific options and no_data=X to get fields collection only and eliminate other possible issues and it also failed with an empty RfcAbapException.
It's just start happen suddenly, the code has not been changed from 2011.

Also we are still using the old .Net SapConnector 2.0.0.26 for this legacy project.

Other tables like MARA, for example, returning data properly using same code. Can you please advice what can be the issue?

RFC_DB_FLDTable fields = new RFC_DB_FLDTable();
RFC_DB_OPTTable options = new RFC_DB_OPTTable();
TAB512Table datatable = new TAB512Table();
proxy.Rfc_Read_Table("|", "X", "V_IBIN_SYVAL", 0, 0, ref datatable, ref fields, ref options);

Creating RFC function module , Its Web services in SAP & Testing using SOAPUI.

2024-05-18T14:25:20.820000+02:00

Introduction:

By leveraging RFC, organizations can enable robust data exchange and process integration across different SAP and non-SAP systems.

However, creating RFCs is only half the battle. To harness their full potential, these RFCs often need to be exposed as web services, providing a standardized way for external applications to interact with SAP functionalities. This is where the power of web services comes into play, bridging diverse systems and enabling seamless, real-time data transactions.

But how can you ensure that these web services are functioning correctly? This is where testing tools like SOAPUI become invaluable. SOAPUI allows developers and testers to validate the performance, security, and reliability of web services before they go live, ensuring smooth and error-free operations.

In this blog post, we will dive deep into the process of creating RFCs in SAP, transforming them into web services, and rigorously testing them using SOAPUI. Whether you are a seasoned SAP professional or a newcomer looking to enhance your integration skills, this guide will provide you with the insights and tools needed to master SAP web services and ensure their optimal performance.

STEPS

Create a function group in SE80.

2.Provide the package name & click on SAVE.

3.Activate the FUNCTION GROUP.

4.Execute the T-code SE37 & Create a FUNCTION MODULE.

Give the Function group name, short description & click on SAVE.

Click on the Radio button REMOTE ENABLED MODULE

Take some importing parameters in order to receive the values as per the requirement.

Take one exporting parameter to return the message if the value is not found.

Take internal tables in order to store multiple data. Here, Gt_mara is referring to mara structure having some fields like MATNR, ERSDA & Gt_marc is referring to marc structure having some fields like MATNR, PLIFZ.

You can write your own logic to test the RFC FM, whether it returns some value or not.

Now, check the result by providing input values from MARA & MARC

12.now, create its webservice from function module.

13. Provide the service definition & description.

14. Below we can see the service definition properties. And activate it.

Execute the T-code SOAMANAGER in S4HANA.

Click on to the Webpages.

16.Provide your Hana-user id & Password.

17.Click on web service configuration.

18.Choose the object type as Object Name and pass the correct service definition name. If the service definition exists, then we can be able to see ‘entry found’ otherwise not found.

19.Now, Click on Internal Name --->Click on Create service.

20.Fill up the details like service & binding name, Provide security, SOAP protocol & Operation settings.

21.Fill up the provide security

22.No need to fill out SOAP protocol details so, click on next. In operation settings click on finish.

23.Then Choose the service & activated--> below interface will open--> click on save .

24.Select the service & click on republish

Click on save

26. Don’t provide any details, click on OK.

27. Click on the below Execute button under the WSDL generation.

28. Press CTRL+S and save the file in WSDL format.

29. Now, we are ready to test the service in SOAPUI. So, let's download the SOAPUI.

Notes:

how to Download the SOAPUI software & implement it.

Go to SOAPUI.ORG website and download SOAPUI open source.

Below is the interface of how the SoapUI looks like. can start doing the API testcases.
Click on soap-->new soap project--> give a project name -->choose the WSDL which we have downloaded -->ok

Click upon request1 then we can see the details in XML file.

To access the data, provide the authorization. Click on add new authorization.

Finally, we can see the result as shown below. For success the status code will be 200.
