MM06E005 - Change or Create mode ME21N, ME22N - GET_TRANSACTION_STATE

Question

We need to find whether the PO is in create or change mode.
In program SAPLMEGUI, there are calls to method GET TRANSACTION_STATE.  Here is an example:
    call method l_header->get_transaction_state
      importing
        ex_trtyp = l_aktyp.
Now then, when you are processing an EXIT screen say SAPLXM06 0101 and you are in the PBO, how can you call this method?  What class is already resident and available?

Answer 1

Hi
Don't u need to use any IMPORT, u need to consider that fm EXIT_SAPMM06E_006 and 0101 belong to the same function group (XM06), that means the both object can see the global data defined in top include ZXM06TOP.
So u need to define a variable like I_TRTYP where u can stores the value trasnfered by EXIT_SAPMM06E_006:
INCLUDE ZXM06TOP
DATA: V_TRTYP(1) TYPE C.
INCLUDE ZXM06U36
V_TRTYP = I_TRTYP.

PROCESS PBO.
  MODULE LOOP_SCREEN.
MODULE LOOP_SCREEN.
   IF V_TRTYP = 'A'..
     LOOP AT SCREEN. 
        SCREEN-INPUT = 0. " I suppose the field are designed for input/output
        MODIFY SCREEN.    "so SCREEN-INPUT = 1 by default
     ENDLOOP.
  ENDLOOP.
ENDMODULE.
