Index ERD of table VBAK
I want to create an inedex for table VBAK that has the date of creation (ERDAT) in it. I just saw that there is already an index ERD that exactly has that field. But the index is marked as "no database index".
Does anyone know if I am allowed to change this index so that it is a database index?
I know how to do this and I know the benefits but my only question is if I am allowed to do this. I don't want my changes to be undone with a future support package or so. Currently I am asking myself why this index is marked as "no database index" as ERDAT has many distinct keys and this should boost performance in any case...
Thanks in advance,
