Not able to find work items in table SWIWIOBJCT

Hello Experts,

I am not able to find certain work items in SWIWIOBJCT table. From what I understand, all work items should be logged into this table.

I avoided SWWWIHEAD during the initial design since it did not had all required data that I wanted.

Can someone tell me why the entries for work item are not coming in SWIWIOBJCT?

Thanks,

Arun
