When testing in-flight masking with Subset on DB2 z/OS, we received an error applying HASHLOV to 5 out of 19 columns with masking transformation maps. We found that the MAPCSV PDS was not created wide enough, so we increased the size to an LRECL of 2000. After that, we received the error that 5 columns had an error applying HASHLOV. We removed those 5 columns and were able to run the GTXMSKL job successfully. Will development fix the drop downs to reflect what is actually available for DB2 masking?
