Error in invoice calculation scheme

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.
