I followed along with the documentation to create a custom data field for contributions, and I can see it when processing contributions, but I am unable to use it as list criteria, even though I added the Detail_Tbl and Detail_Col entries as instructed in the T_KEYWORD documentation. I'm sure I'm just missing something stupid but I'd appreciate any help I can get. We're on v15.1.1 in case that matters.
Known bug, don't believe it's been resolved since 14.1. I've had to create my own lost builder elements for each custom field.
