How to find out System Status of WBS Elements?

Hi PS Experts!

Please help me on my query.

I want to get a list of WBS elements whose status is Released and can be used.

If I try to search the table PRPS, it can only help me in finding WBS elements without deletion flag, with RA Key and so on.

But the System status (such as Blocked for use) etc. is not present in the table.

The one way I know is to get Object Number of WBS element from PRPS Table and insert it in JEST Table to get system status.

Or alternatively, I give the WBS element no. in CJ20N t-code, and then check for System Status.

These 2 methods work, if I do it one WBS Element at a time. If I need to get thousands of WBS elements in such a fashion, it's tedious.

So could anyone help me on this issue?

Thanks in advance,

Vinitha.
