Purchase Requisition Workflow

Hi Team,

When we create a Purchase requisition from Iprocurement wherein the preparer and requestor are different and the Requisition amount is less than the requestor Approval amount,and when we submit the requisition its going in the Pre-approved state not in Approved state and going to the next approver of the requestor hierarchy.

We also could find that the current_Sequence_num column of po_approval_list_headers and po_approval_list_lines tables in the standard pub 'PO_APPROVALLIST_S1' which is using in the workflow is causing the issue as such.

We would like to know like when/how this column value would be populated and when it would be updated as such.
