Yes you have to create a secondary index database . LCHILD and XDFLD of original DB and secondary index should point to each other. Basically it is done in DBDGEN. Please contact your DBA to get it done. Application programmer has to just use the secondary index database name in the PROCSEQ parameter of PCB. and use the secondary index key field in the SSA.
Suggest you to contact your IMS DBA for creating secondary index for an existing DB. _________________ Payilagam Chennai
