Analysis of how to get fiscal acount document by BDC

The program create acount document using BDC--display_mode = 'A'.

After user input all the required fields and create a new document,

program gets the new document and updates local database table.

 

 

below is the original method of getting the document:

  LOOP AT ITAB WHERE MSGTYP = 'S' AND MSGV1 <> ''.
    check itab-msgv1+0(1) = '5'.
      lc_msgv1 = itab-MSGV1+0(10).

  ENDLOOP.

But it often fails to get the document number which has been created.

Finnaly we use this method:

 GET PARAMETER ID 'RBN' FIELD lepid.
