Can you please brief more what exactly you are looking for ?
Since if you want to bring the custom property on the file data cards, you must have a variable mapped in EPDM.
I know how to work datacards. we have accustom property that was not included when we implemented EPDM that now we want to see a list of. so the output we are looking for is a 2 column list. file name in column 1 and custom property value in column 2.
