SRM BRF : Workitem not stored in SRM Table for automatic approval

Hello All,

We are configuring BRF Workflow for SAP SRM  Shopping Cart  Automatic approval , we have followed the standard process using  the evaluation "

3EV_SC_600_000" and  SC is getting automatically approved.

But Work item id is only showing up in Shopping Cart "Approval Preview" , same is not available in  BBP_PD  or SWi1 ,basically it is not stored in the backed tables.

Can someone give an idea ,, what is the wrong with it.

Thanks

CB
