Hello Bryan,

You should never select data in a loop.

Best way would be fill buffer tables before the loop with all entries you need and catch them with read table.

to get the count in your special case it maybe would be faster to buffer all relevant entries from table "aufk" and count them manually in your program.

Next performance Killer is a select with a "<>" or "NE" statement. Better use " = space" instead of "<> 'X' " if you only have X and space inthis field.

Hi -

1. Do not write SELECT statment inside the LOOP and ENDLOOP. Instead, Use FOR ALL ENTRIES.

2. Try to pass as much key fields to where condition

3. First take data to internal table for each SELECT from database tables

4. You can do manipulation / calculation on the internal tables after having the data.

Hope it helps.

Let us know, if you face any further help.

Regards,

Atul Mohanty
