We have a question regarding CCS individual invoice processing. When we try to process an invoice using transaction EA19 (Create bill: individual creation), the system asks for a reconciliation key. During our class, we were able to freely assign any key but now, the system gives an error when we try to execute the run with a key defined by us.
The error says: Reconciliation key XXXXXXXXXX not yet created. XXXXXXXXX is whatever we typed into the field.
