Error when modifying SY-SUBRC in S/4HANA Cloud Public systems using Eclipse debugger

[DiegoValdivia]

Hi guys,

When I try to modify system variable SY-SUBRC in S/4HANA Cloud Public systems using Eclipse debugger, I get the following error message:

Important points to mention:

• I did a test in 3 different Cloud Public systems, all of them showed the same error.
• I tried on some On-Premise systems and was allowed to modify the variable without any issues.
• I searched for posts or SAP Notes talking about any restriction, but didn't find anything.
• I'm allowed to modify any other variable

Does anyone know anything about this issue?

Thanks in advance.

Hi @DiegoValdivia 

please have a look at Setting Your Own Variables in the ABAP Debugger in the Context of Public Cloud:

In ABAP environment, you have the following possibilities for doing changes while debugging:

• You can only change your own variables.

• You can use the function Jump to Line in your own ABAP source code only.

...

you cannot ....

• Change system fields (for example, <SY-SUBRC>)

...

Best regards
Kai
