Hi..

please make sure that u are not using select * , and are selcting only those fields which are required...That may be one reason of the select query taking longtime..U can paste the select query so that we can get a clearer picture...

This will always be slow for large data volumes, since CDHDR is designed for quick access by object ID (in this case material number), not by date.

I'm afraid you would need to introduce a secondary index on OBJECTCLAS and UDATE, if that query is crucial enough to warrant the additional disk space and processing time taken by the new index.

Hello

1. Use your query in LOOP...ENDLOOP with OBJECTID field.

2. Make a secondary index.

Have you got a range of objectids you could use?

eg. 0100000000 - 090000000 depending on your matnr range
