I am trying to modify the Bill of Materials Picking Sheet for version 4.10. I created a checkbox UDF for the CI_Item File (because I can't on the IM1 file) to check on if the item should not be printed on the BOM Pick Sheet. I can add the CI_Item file to the Report and it runs without error. As soon as I add a selection parameter to not include the item if that checkbox is selected on, I receive the following error: Failed to Open a Rowset. Column not found: UDF_BOM_NO_PRINT. I have the CI_Item file linked as an equal join from the BM_24 Component to CI_Item Item Code. Anyone know what I am doing wrong?
