To get copa document number returned by “BAPI_COPAACTUALS_POSTCOSTDATA” posting



does not return successful records with generated copa document number.

But in case system need to capture generated copa doc number there is workaround with

implicit enhancement withing bapi as described in doc,

About the Domain

SAP ABAP/FICO module can use this document. This will help them to get generated COPA

document number which is posted by BAPI_COPAACTUALS_POSTCOSTDATA.

Steps involved

The step that needs to be followed is as below.

It’s divided mainly into 2 section .

A. custom program

B. Enhancement

Create a Custom Program like ZCOPA_UPDATE .

Please follow steps given below for this program.

  • Export BAPI_Call indicator from your program to memory id

          This indicator will make sure enhancement will be trigger only in case bapi will be called for custom program

     gv_call_copa_bapi_indicator = ‘Y’ .

          EXPORT gv_call_copa_bapi_indicator TO MEMORY ID ‘ZCOPA_UPD_BAPI1’.

  • Call Bapi to post data

       *To post Copa document
           operatingconcern = ip_operatingconcern
           testrun          = ip_testrun
           inputdata        = lt_bapi_copa_data
           fieldlist        = lt_bapi_copa_field
           return           = lt_return.

  • IF lt_return[] IS INITIAL ,means copa doc posted ,then only read copa document number .

               In case there is any record in return with message type E or A it means there is an error while generating copa doc , so do not import                doc numner from  ID ‘ZCOPA_UPD_BAPI’

  • Importing copa document number from enhancement only if lt_return is initial

          or have S,I,W message type.because doc number can be  populated in error cases also as this enhancement from where exporting  memory  

     ID ‘ZCOPA_UPD_BAPI’ is before actual posting , so always check return table (is initial or have S,I,W message               type only)

          IMPORT gv_memid_copadoc  FROM MEMORY ID ‘ZCOPA_UPD_BAPI’ .

         So gv_memid_copadoc  will have copa document number which is generated.

Create a implicit enhancement like ZCOPA_ENH_UPDATE . 

Please follow steps given below for this enhancement.

  • Create implicit enhancement in FM “RKE_SERVE_ACT_DOC_NUMBER “  in the end of function.

Which will be used during BAPI posting as this FM function to get next available document number for COPA posting , But actual posting will happen after this FM .

So at this stage we will be able to get COPA doc number which will be generated later on and confirm if there is no error in return table of BAPI .

As Actual copa posting perform  is refreshing inputdata table , and not returning success message we need to use this way .


  • Import BAPI called by Custom Program indicator to make sure enhancement will be triggered only if BAPI call from custom program

IMPORT gv_call_copa_bapi_indicator FROM MEMORY ID ‘ZCOPA_UPD_BAPI1’ .

if gv_call_copa_bapi_indicator EQ ‘Y’ .

then only create following steps

  • Define field-symbol  with genric type as line item table which contain copa records is genric type and define workarea with field Belnr.

*As line item table type genric , so get doc no using field symbol

ASSIGN LINE_ITEM_TAB to <fs_copadoc>.

*As field symbol type any defined work area with belnr which contain copa doc no

MOVE-CORRESPONDING <fs_copadoc> to lw_line_item .

  • Get copa document number in variable

      GV_MEMID_COPADOC = lw_line_itembelnr .

  • And Export Copa Doc number to memory id.



Copa document number will be retrieved successfully from BAPI.



This code could be used to get copa document number generated through BAPI  psoting .

      Hi Vijay,

      Thanks for sharing this information. I am working on a similar requirement and now I am able to retrieve document number into my program. 🙂

      However, as you might be aware, this usage of EXPORT/IMPORT is obsolete at present.

      What best alternative/change do you suggest in the above code to avoid using an obsolete concept?

      Thanks in advance.

      After searching through few posts in SCN,

      I came across the following modifications one can make to avoid usage of obsolete method:

      IMPORT gv_memid_copadoc = gv_memid_copadoc FROM MEMORY ID 'ZCOPA_UPD_BAPI'.

      EXPORT gv_memid_copadoc = gv_memid_copadoc TO MEMORY ID 'ZCOPA_UPD_BAPI'.

      Similarly, for other IMPORT/EXPORT pair.

      Feel free to correct me if I am wrong anywhere.

      Hi Vijay,

      good solution, but it's only working if you post exactly 1 Document per BAPI call? I call this BAPI from a Excel VBA Funktion with many lines. I look for a solution to get the number of each line item back, may it's possible to write the line items table into memory at this point and read it into calling programm. I will check this (performance and memory consumption) and post it here if i am successful 😉

      Regards from Bavaria(South Germany),
