BAPI_COPAACTUALS_POSTCOSTDATA Posting document number

Question

Hi,
I am using BAPI  : BAPI_COPAACTUALS_POSTCOSTDATA  for posting documents of type 10, B0 , 12,B2(01,02,03,04 – Paledger no’s).
My requirement is to post records with same document number  for all the 4 currency types in ce10100 table as in screen shot no :
I tried below way
For Paledger number 01 , Belnr is blank and posting document by calling BAPI ,now I am using this posted document number from ce10100 table for rest of the 3 types of documents since my requirement is that I need the same document number for all the 4 types of documents
When I am using this method to post using test run from se37 I am able to post in required way .In my Z Program when i post one document each time by changing currency type(as 10, B0 , 12,B2  )and exit from Program I am able to achieve this functionality but  if I am using same method for multiple records from Internal table it s not working ,it is generating new document number each time when posted as below screen shot
. I am using Transaction Commit also both when testing in Se37 as test run and also in Z Program.
Please help me in this issue.

There is in fact a workaround to this issue.  I see this question asked in lots of places so I figured I would post here:
4) Although the BAPI does not return the resulting document number and the forums say you cannot do it, this is a workaround that is somewhat hardcoding and requires familiarity with the data. In this example, we expect that the ww106 field is a unique value. Indeed, we went so far as to index the CE table. By specifying the ORDER BY clause, we can make sure we grab the most recent entry first. This is captured immediately after calling the BAPI and doing the BAPI_TRANSACTION_COMMIT and WAIT.
CALL FUNCTION 'BAPI...
CALL FUNCTION 'BAPI_TRANSACTION_COMMIT'
  EXPORTING
     WAIT = 'X'
SELECT paobjnr pasubnr FROM ce41010 UP TO 1 ROWS
BYPASSING BUFFER
INTO (wa-paobjnr, wa-pasubnr)
WHERE ww100 = itab-key1
AND ww109 = itab-key2
AND ww106 = itab-key3
ORDER BY PAOBJNR DESCENDING PASUBNR DESCENDING
ENDSELECT.
