Purchase Ledger Categories
This option sets a short list of purchase ledger categories for the supplier. The purpose of this is to save time during the invoice posting and matching process for value falling outside of goods received reconciliation. For example, on trade stock orders, freight will be a common extra cost that requires not only reconciliation, but specific accounting. However solicitors fees will not include trade type charges but professional fees.
This option allows a short list of purchase ledger categories for each supplier which can therefore be related to the supplier's function.
The 
indicates any purchase ledger categories SELECTED for short list for the supplier. UNSEL will remove the selection. Even though those selected will form the short list full access is always available.
