Changed version of a PO is not getting deleted

[Former Member]

Hi Experts,

There is one custom FM changing the purchase order in SRM, it does all the process correctly, however, it does not delete the changed version.

Manual process-

1. A PO is in ordered state and we do change anything in that it creates a changed version. (PO is in Saved status now and it is a change version)

2. After doing the changes, we save the PO and order (auto approval scenario), PO comes in Ordered status and the changed version gets deleted as the Ordered version becomes the only active version of the PO.

Custom FM logic-

1. Update PO with the details using 'BBP_PD_PO_UPDATE' function module

2. Change the PO to Ordered status using 'BBP_PD_PO_STATUS_CHANGE' FM

3. BAPI_TRANSACTION_COMMIT

In the later scenario, the changed version is not deleted, however, in the first scenario , the changed version is deleted.

Please guide me.

Thanks

I get to know that changed version is not deleted after manual operation but it gets converted to historical version.

What I would need is -

1. A way to transfer changes to the active version from changed version.

2. Convert the changed version to historical version

        gr_po_class = /sapsrm/cl_pdo_factory_po_adv=>get_instance(

           EXPORTING

             iv_header_guid                 = pv_guid  "gs_ac_header-guid " Globally Unique identifier

             iv_mode                        = 'DISPLAY'    " Process mode of PDO Object Instance

             iv_process_type                = 'ECPO'    " Business Transaction Type

             iv_user_id                     = sy-uname "gs_ac_header-changed_by

         ).

    gr_po_class->/sapsrm/if_pdo_bo_po~order(

       CHANGING

         co_message_handler             =  gr_o_msg_cons   " Methods for message handling

     ).

          gr_po_class->/sapsrm/if_pdo_bo_po~complete_po(

             IMPORTING

               ro_new_po          = gr_ro_new_po

             CHANGING

               co_message_handler = gr_o_msg_cons    " Methods for message handling

               ).

Worked for me (obviously exception handling is vital here). The problem got resolved after using complete_po method of PO PDO interface. This deletes the changed version.

Thanks
