Error in invoice calculation scheme

Question

Hi dears
I have two calculation schemes ZXXX3 and ZXXX31. The second one was created as a copy of ZXXX3, nothing was changed in it.
I assign the new scheme ZXXX31 to my sales area, create sales order and then create invoice via vf01 for this order without problem.
Then I assign the old scheme ZXXX3 to the same sales area instead ZXXX31, create sales order and try to create an invoice. But I can't save it because is shows me an error "interface RW: document data header are inconsistent for updating"
ECC6.0 system
I have equal sales area, customer, material, data and so on. I have difference only in scheme name. The condition exclusion rules are the same for both schemes.

Answer 1

Hi, Phanikumar
I check these schemes in the test system, there fore I can take the same customer / material / quantity / organization data and so on. The pricing procedure is the same in sales order and in invoice.
The invoice is hitting RW because the accounting  document is created with reference to invoice, e.g.
Account determination is definited in calculation scheme by accounting key ERL:
The condintions ZPR1 and ZR02 are in different exclusion groups
and these excluding groups are assugned to both calculation schemes.
I've found that if I delete ZR02 condition from ZXXX3 cheme it begins to work. But ZXXX31 works with this condition properly. The scemes were created as copy of each other.
