PDO Layer Error in change version PO

Question

Hi,
We are in SRM7.0 , EC Scenario
In SAP SRM system am experiencing a workflow issue , second level approver is not able to approve/receive the workitem of a changed PO. Moment 1st approver approve it and when requester try to open the PO (changed version) and navigate to Approval tab, the approval flow is missing and showing the error as
PDO Layer Error
An Exception has occured
Every time we must restart the workflow due to which the approval needs to be done again from 1st approver.
We have raised an OSS Message and following is the response from SAP
" The second approver does not get a workitem because the workflow got the status error. The cause of this error is your BADI implementation ZCL_SRMWF_AGENT_PO_BUYER method
/SAPSRM/IF_EX_WF_RESP_RESOLVER~GET_AREA_TO_ITEM_MAP. This method returns an initial table LT_AREA_TO_ITEM_MAP.
Run method CREATE_DECISION_SETS (/SAPSRM/CL_WF_PROCESS_MGR_SBWF) with
parameter IV_PROCESS_GUID = change version guid xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx "
When i executed this method CREATE_DECISION_SETS (/SAPSRM/CL_WF_PROCESS_MGR_SBWF) with
parameter IV_PROCESS_GUID = Changed version PO GUID , i got the following error
Exception CX_BO_ABORT triggered
Termination triggered in '' - Rollback required
Can anyone please help !!
Thanks & Regards,

Hi Sarvanan,
I am a functional consultant and completely unaware of this technical stuff. Since this is SRM BRF workflows, none of our workflow consultants also are able to help me out on this issue. So, if possible could you please let me your contact number to so that i can contact you directly on this issue.
This is the issue which i am facing from last 7 months and none of the person is able to help me out. So, i kindly request you to please help me out on this issue.
As requested following is the code for the process level class

                        WITH KEY bukrs = ls_header-co_code
                                 matkl = lw_item-category_id.
    IF sy-subrc = 0.

    APPEND lw_approver_item TO rt_approver_item.
    CLEAR lw_approver_item.
  ENDLOOP.
ENDMETHOD.
