N Step BADI Approval Workflow Error in SRM 7.0

Question

Hi,
I have implemented SC  Workflow Approval based on line item(sequential approval). I implemented process controlled workflow for this using N step Badi. Necessasy configuration done for each level at schema. All steps are executed per line item and agents determined using N step Badi /SAPSRM/BD_WF_RESP_RESOLVER.
Even in SC after the document is ordered, in approval overview tab i see the all level sequence with  approvers name for that  line item.
But when approved by first approver, it doesnot move to the next level for approval and the SC is approved bypassing all approvers in the following levels.
For example, if there four levels of approvals for one line item. as soon as the first approver approves the SC is approved and in SC Approval Overiew tab that contained four level of approval in it is now reset to one level with SC marked as appproved.
Have anybody come across this error.
Not able to figure out why it is happening so... need some expert advice.
Thanks in Advance.

Hi Masa .. thanks for your reply.
Was on vacation so could not reply.
I have below settings in SRM for SC
Process Level definition should be like this.
Level Eva.ID ; Resolver Task ID Decision Type
100 L100 R100 40007953 Item-Based decision for Partial Doc.
200 L200 R100 40007953 Item-Based decision for Partial Doc.
300 L300 R100 40007953 Item-Based decision for Partial Doc.
I have implemented /SAPSRM/BD_WF_RESP_RESOLVER for R100.
for grouping we are using line item number ... so each line item is a group.
Below are issues that i am facing now.
For say 2 line item in a SC... with 3 level of approvals for each line item. I am not able to approve one line item in a sequence. For example: If for first line item, when I approve level one .. then the workitem doesnot move to 2nd approver's inbox for that line item. Now if second items (asssuming there are only 2 line items in SC) first approver has approved then i see all second level of approvers available for all line item.
In short system waits for all one level approvers to approver for all line item and when all the line items are approved at one level then the workitems are available for seconds level of approval.
Is this the standard behaviour?
As per our requirement we wanted one line item shoudl follow the approveral sequence without being dependent on other items approval.
