Hello Experts Hope everyone is doing well ,

I was wondering how I am going to post the DATA in ECC of a XML  MESSAGE received from PI  with a successful message status in SXMB_MONI.

In some scenarios it may happen that there might be a programming bug in the Provider class method which actually processes the payload content of the XML message.

This bug may lead to inconsistency like the actual posting of the data is incomplete Or not done at all and the messages ID status is still Successful in SXMB_MONI.

Now how are we going to reprocess the Successful message again? One option is that the source system should resend the data OR there should be a mechanism which processes such kind of messages.

There is some custom program available to regenerate the same XML payload with a different XML message ID and then Process it within the ECC system itself. This approach leads to multiple XML ID with same payload.

What if I could just extract XML payload from such message ID and process them using the provider class method .

I carried out the below steps to achieve same.

  1. Read the XML Content (Payload) of the XML message from the message ID.
  2. Call the XSLT transformation for the XML string obtained in step one.
  3. The XSLT transformation will give you the data formatted in INPUT structure (i.e. Importing parameter) of the method of the provider class which actually posts the data in ECC.
  4. Create an instance of the Provider Class of the interface.
  5. Pass the Input structure to the appropriate provider class method and invoke the same.
  6. The message will post the data into the system.

This would be just like you are testing the Interface using transaction SPROXY and posting data.  This won’t create any temporary XML ID.

ABAP Code for same would somewhat look like this :

DATA : persist_main TYPE REF TO cl_xms_persist.

DATA : xmb_msg_main TYPE REF TO if_xms_message_xmb.

DATA : payload      TYPE sxms_mmfpayloads.

DATA : wa_payload   LIKE LINE OF payload.

DATA : abc TYPE REF TO if_sxmlp_data_st.

DATA : xslt_t TYPE cxsltdesc.

  CALL METHOD persist_main->read_msg_all " Read Messages attibuts
im_msgguid = wa_idtab-msgguid “  Message ID
im_pid     = wa_idtab-pid
im_version = wa_idtab-rest_vers
ex_message = xms_msg_main.

xmb_msg_main ?= xms_msg_main.
"  Type casting

CALL METHOD xmb_msg_main->get_main_payloads " Get the payload object reference
return = payload.

READ TABLE payload INTO wa_payload INDEX 1. ”read at index one coz we are processing one xml id at a time

"Fetched the payload of XML ID

CALL METHOD wa_payload-mainpayload->gettextcontent ” extract the text contents form the play load
return = wa_str. " This string contains the actual pay load xml data in text format
