ICWC: Change documents for ibase/instance

Hi,

in our ICWC when a user changes the ibase/instance of a process there is no change document written.

I know how to turn on the change documentation of an object used in a process. The object has to be defined as relevant for change documentation (in CRMV_OBJECTS). And the fields which should be documented also have to be signed as change document relevant (further characteristics of the data element -> check change document).

My question is how to document the changes of ibase/instance changes. I did not find the correct table. In report CRM_ORDER_READ the instance information of a process is found in table ET_REFOBJ. So first of all the object REFOBJ is not signed as change documentation relevant in table CRMV_OBJECTS. I think I have to change that first?!? Right?!? But which data element do I have to sign as change documentation relevant?

Best regards,

Ben
