dear experts we are facing a big issue since couple of days when we define rate in EA31 the following error creating problem . in main and sub transaction level we assigned for 100 main sub 0001 & 0002 for internal assignment, and 0010 & 0020 for normal external assignment we din't do any settings before it was working fine now the following error creating so much, can any one try to guide me get up from this prob...
Error:Sub-transaction 0020 has a special meaning
Message no. AH671
Subtransaction 0020 in combination with main transaction 0100 exists in table TFKTVO. These subtransactions have a special meaning (such as transfer postings in invoicing) and can therefore not be used in the rate steps.
Table TFKTVO contains a subtransaction for main transaction "Consumption billing" that is used in invoicing to find the receivables account. You cannot use this transaction to allocate a revenue account to a rate step.
Thanks and regards
