I created one main item and several sub items while I am processing the sales order and enter the main item, system requested to enter the qty for the main item. Then, I enter the quantity after enter the quantity the system shows an error (No item available table T184 or LUMF TAQ)
I created the BOM by using the the transaction code CS01.
in the main item item category was assigned to ERLA and sub item was assigned to LUMF
Thanks in Advance
