In some cases you may see that in the Transformation Map screen of Datamaker that the drop down for masking functions is EMPTY for the DB type of FILEMASK. This article will explain how to successfully create a transformation map for registered FILE or DB tables if this is encountered.
Traditionally our tool Fast Data Masker's (FDM) GUI is used to for masking purposes for Databases for Files. However, there are cases where the Transformation Map screen of Datamaker is used to create and store the masking files in case the FDM GUI is not available for your environment or if you are using our Mainframe masking tool, which also does not have any interface.
You already have a file or the tables for which the transformation map needs to be designed for are registered in GTDatamaker's version inside your Project.
Steps to reproduce this issue:
The drop down is "EMPTY".
Case 1: There are no Data Functions defined under the "Tools->Maintain Data Functions" screen for the DB type "File".
Case 2: While creating the Transformation map, you have accidentally selected "File" instead of "FILEMASK" as the DB type.
