While debugging in Eclipse, I get an error “no authorization to change variable 'xxxxxxxx'”

[Sasaki1]

I am implementing and testing custom logic on the extension point “MM_PUR_S4_PO_MODIFY_HEADER” in S/4HANA PUBLIC CLOUD.
I want to change SY-SUBRC and variable values during debugging in Eclipse, but I get the error

“no authorization to change variable ‘xxxxxxxx’” and cannot change them.
I have assigned the business roles “Extensibility Specialist:
BR_EXTENSIBILITY_SPEC” and “Developer: BR_DEVELOPER” to the PUBLIC CLOUD user ID.
Please let me know if you know of a solution.

Hello,

Hello, have you found a solution? I have the same problem...

The cause was found.
When implemented from a Public Cloud custom logic app, the ABAP language version is for the key user.
Eclipse does not support value editing during debugging with this language version.
If you want to edit values during debugging, you need to do a BAdI implementation within Eclipse.
