Schedule lines tranfer from R/3 to SUS in a MM-SUS scenario

Question

Hi SRM gurus,
We are working on the MM-SUS scenario where the scheduling agreement is created in the backend R/3 system. Delivery schedule lines are generated in the backend and transfered to the SUS thru. ME9E transaction for sending the delivery schedule to the SUS.
We have a confirmation control key which guides us in SUS to create an ASN in the backend.
Though there is a confirmation control key exist in the SA for that particular line item, when the ASN is sent from SUS to XI to R/3. There is an idoc error in the R/3 which says that there is no confirmation control key though it is there for the line item which is transfered to SUS.
Now Pls. answer my questions :
1) Will ME9E transfer the total lines in the SA or the schedule lines with the delivery schedules only ?
2) Is it possible to resend the same schedule line ( with the updated delivery schedule) to the SUS as per the standard scenario?
3) In the SUS how do we findout the materials corresponding to that particular delivery schedule line. Because in SUS the reference is only the scheduling agreement number as we could not see any scheduline line item.
Pls. suggest.
We are working on SRM(SUS) 5.0 with ECC6.0 as the backend.
Best regards,
Sridhar.

Answer 1

i have seen the code --> where the FM is called for creation of SAR in SRM.
that is FM
BBP_SAPXML1_SUSPO_CREATE_IN --> in this --> search for this
Call API
      IF ls_header-description EQ 'DELINS'.
        CALL FUNCTION 'BBP_API_SUSPO_CRT'
        EXPORTING
          is_header   = ls_header
          it_item     = lt_item
          it_attach   = lt_attach
          it_partner  = lt_partner
          it_longtext = lt_longtext
          it_tax      = lt_tax
          it_limit    = lt_limit
          it_sdln     = lt_sdln
        IMPORTING
          es_header   = ls_header_e
this one creates ---> the SAR in SRM.
and also i have seen further --> there is no place where any BADI is also called.
i am afraid it is not possible to control what you want using BADI.
only --> difference between --> New document and the old document is
the Indicator --> C for create
U for update.
And Also if you can see the XML message for the updated document --> you can see all the lines in the XML message.
Not the added lines...
