Passing data from one session to another session

[Guruchander1]

Hi,

I need to pass data from one LUW to another in my SAP system. Initially, I tried using Memory ID, but I encountered issues when multiple sessions attempted to update the same Memory ID simultaneously.

In my system, Shared Memory is not allowed, so I am exploring other options. I am considering using a persistence mechanism, but I don’t want to create a custom Z table to store the data.

Is there a way to achieve this using standard SAP features, such as persistent objects, temporary cluster tables, or any other alternatives?

Thanks in advance for your suggestions!

Transferring data from LUW to another is not sufficient to understand what your code is about, and to propose a solution. What are you doing exactly? Is it asynchronous RFC, update task, background job, etc.? What version is your (very) old ABAP system? Why don't you want to create a custom Z table?

NB: rest of question asked in another question here: Enhancement to Update NAST in VA02 - SAP Community. Why not gathering them in only one question?

Perhaps your current solution with using a Memory ID can be "fixed", if you use standard "enqueue technology" for preventing simultaneous updates by multiple sessions. See the ABAP reference for how to create and use an ENQUEUE-object.

Alternatively, the "ABAP Intermode Communication" might be used to solve your requirement. Unfortunately, I didn't find any documentation for it. Will update here, if I can find something.

depending on the use case, shared objects may also be an option. if shared memory is not meant by this.
