As of Release 4.0, lists of the following documents in Sales and Distribution are managed by the Basis tool, the ABAP list viewer:
The list viewer enables you to manipulate the list display interactively. You no longer have to define settings for list displays in Customizing.
The Customizing activities for lists will not be deleted as the following activities still need to be performed:
Please note that the system only takes the above Customizing settings into account. It ignores any other settings you make in Customizing for lists.
If you want to convert your existing display variants so that you can use them in the list viewer, run report SD_UMSL_T180S_LISTVIEWER.
For detailed information on how to use the ABAP list viewer, see the cross-application documentation in the R/3 Library.
