Hi,
I have a Z-Table. The Primary key is:
EQUNR and LFDNR
I created now a new index with the field: EQUNR BSTNK .
Now I entered 3 equnrs and bstnk like 07* in SE16n
Normally what I thought should happen is that it uses the index to read the three equipments and than checks the field bstnk.
Instead it does a sequentiel read of the hole table that contains 12mio entries!
When I enter the bstnk more qualified like 0712354* the search is fast (1sec). Why is SAP bypassing the index and does a sequentiel read instead?!
