I think you can check Transaction Code in BADI.

Hello Alexandre

It would be possible to check the transaction. However, if the BAPI BAPI_PO_CREATE is used the BAdI is also processed yet the transaction is most likely wrong.

An unambigous approach is to check IMPORTING parameter IM_TRTYP in method IF_EX_ME_PROCESS_PO_CUST~OPEN:


METHOD if_ex_me_process_po_cust~open.
* define local data
  DATA:
    lo_po          TYPE REF TO cl_po_header_handle_mm,
    ls_header      TYPE mepoheader.

  me->md_trtyp = im_trtyp.  " save transaction type

  IF ( im_trtyp = 'H' ).  " add new purchase order
...

I would add an instance attribute MD_TRTYP to the BAdI implementing class and save the transaction type in method IF_EX_ME_PROCESS_PO_CUST~OPEN (see above).

Now you can simply add the following IF condition to your POST method:

METHOD if_ex_me_process_po_cust~open.

  CASE me->md_trtyp.  
    WHEN 'H'.    " add new purchase order
  ...  " do required action for CREATE

    WHEN ... .

    WHEN others.
      ...
  ENDCASE.
...

The possible transaction types can be found at: im_trtyp -> data element -> domain (fixed values).

Uwe

Thanks Uwe, this is what I was searching for, I never thought to look in the open method.

I give you 10

Hello Alexandre

You are welcome!

Since BAdI interface usually do not have that many methods I usually "browse" through all methods and their parameters to get an idea about the function of the methods (because, sadly enough, they are poorly documented).

I face the same problem as I need to have some logic implemented in the close method if it is a create PO action.

When I try your coding in METHOD if_ex_me_process_po_cust~open.

me->md_trtyp = im_trtyp.

I get 'Field "MD_TRTYP" is unknown. It is neither in one of the specified tables nor defined by a "DATA" statement.

Besides, I would like to ask if I can declare a global variable to be shared within the different methods in the BADI ME_PROCESS_PO_CUST.

Hello Gundam

I have defined MD_TRTYP (most like of TYPE trtyp) as private instance attribute of the class implementing the BAdI interface. This way the transaction type is available in all methods of the BAdI.
