Looking for something else?
Ever wondered if the standard MM Purchasing reports (eg. ME2L, ME2M) could be made available in ALV instead of
the "multi-line" report?
Not to worry. Go to MM -> Purchasing -> Reporting -> Maintain Purchasing list -> Scope of List -> Define scope of list, in customizing. In this, check the box use ALV grid control.
I do wonder though why this feature is available in customizing.
