COAS/AUFK ZZ fields not derived to COPA in settlement rule in KO01 (only KO02)
I created ZZ fields in internal order (AUFK/COAS) using exit COOPA0003 (EXIT_SAPMKAUF_002), and I created rule in KEDR to derive these fields to COPA WW characteristics using COAS table as reference to pick up the ZZ fields.
When I create the order (order number is external), the settlement rule is generated automatically, and, for example, Profit Center is automatically derived in the settlement rule.
But the ZZ fields are not. Only when I enter KO02 to modify de order, the derivation rule works.
Can you help me? Why is it not working in KO01? The internal order number is alredy determined in KO01 as it is external, so I don't see why the information is not derived.
O ABAP consultant only enhanced the exit EXIT_SAPMKAUF_002, not the exit EXIT_SAPMKAUF_003, can it be the reason?
I don't want to use COPA enhancements, I'd like to derive from standard table look up in KEDR...
