Posting header data for MIGO thru badi

Question

Hi,
I'm using badi  ' MB_MIGO_BADI ' for posting header data for the T-Code MIGO.
I have created an extra tab for supplier details for header data. The details from dis tab should be stored in a ztable.
I have written the code for the same in the METHOD  'POST DOCUMENT'  of the badi, but m unable to store the data in the ztable. niether is the code for display working.

Hi,
you need to create an attribute where you will store data from your additional screen. In example there is an attribute GS_EXDATA_HEADER with structure MBLNR, MJAHR, BADI_NUMMER. So obviously the point is to enter some number on additional header tab screen. You can see that in the method PAI_HEADER that all data from screen are transferred to this structure and in the method PBO_HEADER are data transferred from internal structure to the screen. So in this internal structure you store the current values of the fields from your additional header tab.  Now when you store material document you want to also store your additional data into database. Until this point you store it only in memory. Hence you prepare a new FM which will store this data to DB and you will call this FM in UPDATE TASK. Here is an example
  CALL FUNCTION 'MIGO_BADI_EXAMPLE_UPDATE_HEAD' IN UPDATE TASK
    EXPORTING
      is_migo_badi_header_fields = gs_exdata_header.
Once again to summarize it:
1) Define your own structure to keep additional data as an attribute of BADI implementation class
2) Pass data from memory to screen and back using methods PBO_HEADER and PAI_HEADER
3) Store additional data into DB using FM called in UPDATE TASK from method POST_DOCUMENT
