We are now using dynamic credit control. But a question confused me a lot when I use item category TAB or TAS in sales order. You know if you create normal order by using item category TAN, sap will check if the first delivery date falls in the credit horizon. If yes, the core credit limit check will be performed. Else if, then core credit limit check not performed. But in TAS or TAB, it seem sap will directly perform the core credit limit check without checking the credit horizon. Is there anybody can help me on it?
