I recently learned how to import Bills into the AP.
There is an issue that has been recognized with the APinvMulti.csv import. I noticed that a bill being coded with multiple lines of distribution is separated by columns for the invoice distribution. Refer to (https://kb.blackbaud.com/articles/Article/41638).
This process of entering the data into different columns increases the import time for each bill. Its actually easier to do a manual entry into FE, rather than performing an import in this fashion. There is always the issue of screen real estate and its is always more time consuming to add, review and reconcile additions across columns on a spread sheet.
My suggestion is that for bills, that are coded with multiple lines of distribution, should have an import set up so that there are different Rows of distribution.
