Delete Report Variants
Deleting the existing Report Variants can be done easily by selecting the desired rows and clicking on the delete button in ALV toolbar.
Any Report Variants that are still in use in the Backend Testing will be locked; therefore it is first necessary to delete these Report Variants from the given runs (or specific runs) before proceeding in deleting them permanently from the Report Variant Editor (i.e. system).
Transport Report Variants
It is possible to add the specified Report Variants to a transport to be transferred to another system (with KATE installed). To specify which of the Report Variants are to be transported you need to select them from the list. There are options for filtering and sorting in the ALV table that can be used to select the specified Report Variants more easily.
Selecting Report Variants to be transported
After selecting the desired Report Variants and clicking on the 
'Transport Report Variants' button, choose your transport request. You can select the request and confirm the transport for the selected Report Variants.
It is important to note that the Report Variants only carry information about KATE related items, and not the transformation structures themselves so they should be imported only to system where KATE is installed and the same reports/variants with same structure exist.
Edit Report Variant
You can edit the existing Report variants by double clicking on them in the table view. Only Variants that are not already in use in Test Runs can be edited. If a Report Variant is already used in the Test Runs, then the details can only be reviewed but not changed.
When variant details are displayed you can check where this variant is used. By pressing the 'Where Used' 
button a table is displayed that contains all Test Plan/Test Case/Run ID information where this variant is used.
