Hi Techies,

Source Code :

DATA:mo_pdo TYPE REF TO /sapsrm/if_pdo_base.

DATA:lo_pdo_po_text    TYPE REF TO /sapsrm/if_pdo_do_longtext.

TRY.

         CALL METHOD /sapsrm/cl_pdo_factory_po_adv=>get_instance

           EXPORTING

             iv_header_guid  = wa_header-guid

             iv_mode         = 'APPROVAL'

             iv_process_type = 'ECPO'

             iv_wiid         = iv_wiid

             iv_user_id      = iv_agent

           RECEIVING

             ro_instance     = mo_pdo.

       CATCH /sapsrm/cx_pdo_wf_mode_ban .

     lo_pdo_po_text ?= mo_pdo.

CALL METHOD lo_pdo_po_text->update_longtext

            EXPORTING

              iv_text_preview    = lv_note

*          CHANGING

*            co_message_handler =

              .

Hi Laurent,

I have one question , in PROCDOC_UPDATE method what value I have to pass to parameter : IV_DECISION

Can you please help us on that.

Hello,

cannot help you: you know the business process in which you want to update "Approval note", not me...

Regards.

Laurent.

Hello,

your type ref "mo_pdo" must be a type ref to /SAPSRM/IF_PDO_PD_BO_PO_ADV, not to  /SAPSRM/IF_PDO_BASE.

An alternative solution is to take example with PROCDOC_UPDATE method from class /SAPSRM/CL_OFFLINEAPP_INBOUND.

Regards.

Laurent.
