Adding a UDF to the PR check form - PR v2.19 or v2.20

Client wants to pick from two banks to issue PR checks from.  Since they use blank check stock, I added a second text field for the bank address information.  Doing this in AP, I suppress the text fields based on the bank code.  But I do not see the bank code field in PR_checkprintingwrk.  Not sure why it wasn't include.  So I added a UDF for the bank code.  UDF is populated in the WRK file (viewed field in DFDM).  However when adding the field in the PR Crystal template (via verify database), the field does not appear after updating.  I am wonder if this is due to PII restraints or something else.  I did implement plan B by using the bank account number (actually the MICR code) but still puzzling about the missing UDF.

Any techie insight?
