Hi,

Using a cluster/pool table u need to take care of the following things:

1. U cant place a join on the cluster or pool table.

2. U cant use GROUP statement.

Except the above, a normal select can be used to fetch data.

Hi

Try to use All the 'KEYS' in the where condn while using BSEG table.Also goto its INDEXES and see whether any indexes are available or not..If available rewrite your selection according to that index keys.Also enquire with FC whether you can use bsik ,bsim or bsak instead of using bseg....

Only use BSEG as a last resort after you make sure that selecting from other table such as BSAS, BSIS, BSAK, BSIK, BSAD, and BSID cannot sattisfy your data requirement.

Joining data from other table mentioned above is far better than selecting from BSEG.

But if your ceratain that the only solution is selecting from BSEG, make sure that your query are using all the keys in BSEG in the correct order according to the main index or any of the index provided, but it is strongly advised to select based on all of the primary key on the correct order.

Hi,

As it is a cluster table,there will be huge amount of data.

inner jpins doesnt work on cluster table. The only way is for all entris.

In the where condition , u shud use all Primary keys.

Revert back if any issues.
