When Im executing the transaction MFBF i got this warning message ( CK 694 No structure could be determined for internal activity ), but i only got this message in the first day of the month. In other days i dont get any messages. But every first day of the month i get the message.
If I press back, i get the material document correctly and the message stops prompting until the first day of the next month.
Thx for your attention.
I assume that actual costing, actual cost component split and activity update are active. The system tries to write the activity price and the cost component split to the material ledger tables but there is no cost component split. So, the system creates a simple cost component split by writing the price to one default cost component and informing the user with this warning message.
To get rid of the reason for the warning message you should make sure that the splitting is run in cost center accounting.
