Err in PO creation-Sales document item is not defined for the transaction
I am getting the following error while creating PO
"Sales document item 30000183 000100 is not defined for the transaction
Message no. V1 198
You have tried to carry out a business transaction for this sales and distribution document item which, for this item, is not allowed.
This may be due to the fact that this item is not part of a make-to-order production with cost management in the sales order."
I have used an item category which is copy of TAB and the sales order line item is attached to WBS element.
can any one guide me what needs to be done.
