I'm trying to import three simple tables from Excel into Dataverse. Each table has two columns, one with a Code/ID, one with a Description (human-readable name). I've created the tables in Dataverse within the context of a Solution. When I try to import the tables from Excel, only the system-created columns appear for mapping. I'm mapping the Description to the Name field. This works fine. But I've added a Code/ID field (called Item Code) and it will not show up for me to map from Excel.
What am I missing here?
I also tried adding a fourth table called Test_Item with the same scenario. In this instance, the additional Test_Item Code field was showed up and mapped properly. I don't know what I'm missing. Thanks in advance!
