Hi,

Can some one pease advice on the following,

1-requisition is raised- Trun into a PO-PO goes out to supplier-supplier send the invoice-user match the invoice to th PO.

1.1-IN order to move it to FA- PO categories should have a clearing account - so when Create Mass Addition is run it is picked up and transfer to FA?

-PO Categories Clearing Account- does it has to be from One Asset Category or can have differnt clearing accounts within different PO Categories?
