Insight's GL Mapping tool has two parts:
The GL Import feature, and...
...the GL Mapping Sheet
The GL Import feature imports data you've extracted from your credit union's data processing system.
You will learn about how to perform the actual import later on, in the "Performing the Import" section.
Before you can do this, you will need to help Insight understand your general ledger codes by setting up the GL Mapping Sheet.
