When a multi lined invoice is entered via Pak Docs and each description line differs when it’s pulled into Pak Accounting, all the description lines match the first one. 

In Pak Docs, there are two sections where line item coding takes place.  One section, Detail Items, is necessary only when you want a unique description on each line item OR have a debit invoice with at least one credit line item.  The first scenario, Coding, pertains to what you are seeing.  You must use Detail Items and then Code with Detail items in order to get unique line item descriptions. Attached is the info going over this information.
