TDM 4.9.1 Mainframe Flat file Masking using FORMATLUHN not available in DataMaker


Article ID: 202400

CA Test Data Manager (Data Finder / Grid Tools)


I am using FORMATLUHN algorithm for masking SIN number on Mainframe Flat files. I am using Data Maker to create Transformation MAP FILES which are FTPed to Mainframe for submitting Masking JCL. The issue is that FORMATLUHN is not currently available in drop down list of Data Maker algorithms so I have to edit and add it manually for every file map.


Can you please help in adding FORMATLUHN in the Data maker drop down so that no manual intervention is required.? 





Release : 4.9.1

Component : CA Test Data Manager


This is a known issue in 4.9.1.  

Copy the attached (dmdatafunc_ZOS.txt)  to the Datamaker folder and replace the old one. 

Then do a  ALT-DELETE-M to get to Maintain Connections window to upload the new setting from the file to the repository. 

Additional Information

We will have a fix in the next release 4.9.2, the new repo kit will include these entries.
