S4HC Extensibility: SCBO_AUTHORIZATION/000: You are not authorized to create instance

Hi dear colleagues,

I developed a side-by-side app using Java + SAP Cloud SDK (Neo). The app adds records to a custom business object.

The app was working fine when I concluded development in February. Now, I need to do some additional improvements, but I can add records anymore.

I am getting the error SCBO_AUTHORIZATION/000 - You are not authorized to create XXXXXXX instance.

I assigned CBO to a business role, the custom communication scenario along with communication arrangement is in place. I tested already the service (metadata) and the user is not locked.

Could someone give a clue on where could the issue be?

BR,

Pietro
