TBOM Filter 
You can use the TBOM filter to set whether the Business Process Change Analyzer is supposed to ignore certain objects contained in the TBOM. These objects are not taken into account in the analysis then. Even if these objects are affected by a change, they are not listed as a result.
You can edit the TBOM filter both for a certain TBOM (of a certain transaction) and as valid for all TBOMs. You can also define the TBOM filter specifically for a certain user name or as valid for all users in general.
You can call up the TBOM filter in the following ways:
In the Test Management work center under Settings
In the attributes of the transaction for which you have created the TBOM (TBOM tab)
In the TBOM filter, you can use the following functions:
Copy text of selected cell
Append new rows with filter conditions to the end of the table or insert them at the selected point
Delete rows with filter conditions
Search for a search term in the filter conditions
Restrict the displayed filter conditions with a filter
Check filter conditions
You can use masking characters for almost all parameters. Only the TBOM (TBOM GUID) identifier and the user name must either be filled correctly or be completely blank.
