different BPM approval rules in one requisition causing the approval group to skip

Hi Experts

We created a requisition which has two lines with two different categories:

Line 1 - IT

Line 2 - consultancy

Requisition Approval rules are set in BPM worklist. Task -ReqApproval

Each Category have different rule.

IT category invokes the approval group and Consultancy category skips the approval group and moves to the next stage

since in one requisition both categories are present the approval group is skipped.

we need the approval group for IT category when both categories are in on ereq.

Thanks,

Bhushan
