For some reason we get the column in double for some tables.
When doing a scan Z_ACC and ZXACC both have "column" as a Column Name and it looks like both tables are being brought into the scan. It seems like the "underscore" is acting like a wild card when searching the tables to find Columns.
We tested with 4.9.45
Release : 4.9
Component : CA Test Data Manager
The fixed binary is TDMWeb-188.8.131.52.zip. After applying this version or later and you have a model with the dual column names, you will need to rescan the data model after applying the patch to remove doubled columns. The search will be fixed immediately after the patch application. Please contact Broadcom Support for this version or later to fix the double column issue.
