TBOM Weightings 
You can assign different weightings to the objects listed in the TBOM. For example, you can give tables a higher weighting than user interface elements. You can set a different weighting for every object classification type.
Depending on the setting, Business Process Change Analyzer can restrict the list of objects affected by a change to objects with a certain weighting. This restriction then acts like a filter on TBOM objects that have a certain weighting.
You can edit the TBOM weightings both for a certain TBOM (of a certain transaction) and as valid for all TBOMs. You can also define the TBOM weightings specifically for a certain user name or as valid for all users in general.
You can call up the TBOM weightings 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)
You can use the following functions for the TBOM weightings:
Copy text of selected cell
Append new row with weighting information to the end of the table or insert them at the selected point
Delete rows with weighting information
Search for a search term in the weighting information
Restrict the displayed weighting information with a filter
Check weighting information
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.
