why in service PO , Number of quantity column not available, even it is service PO we required quantity?
for example if the company sending generator (2pcs) means how can we enter that?
not only this one thing most of the client are asking the same
I think this is a system design problem. The quantity column is available for the all types of documents because they share the same table structure. However, the initial designer of the application just blocked qty column for service document.
We have to live with it. To change a software architecture is a huge task that nobody would touch it.
You may manually put the qty in description and add UDF for qty and FMS for the amount.
