ME21N Service PO

Dear friends ,

We noticed that when we enter item category D - service in the line item of PO the qty of this line item is default to 1 and de unit of measure is EA = Each, and fields become greyed we cannot change values there.

Does anyone knows if is possible to change this behavior ?

Best regards,

It is the standard system design for service procurements. This is why because the each and every individual service item has its own Unit of Measurement and this determines the overall value for that PO line item. So the main line item will always have single UOM. But you can change that UOM under transaction code ML91, which will not have any advantage and help you for information purpose apart from any specific business requirement.
