Hello Mutale,
there are 2 steps
1. To have this Tick as Default.
In the include ZXWOCU21 of the exit QQMA0025, put this code.
IF I_VIQMEL-QMART = 'M2'.
E_VIQMEL-MSAUS = 'X'.
ENDIF.
This code sets the Breakdown tick, whenever an Order integrated with 'M2' notification is being created. That is whenever you create PM02 order (integrated with M2 notification) you will see this tick by default.
2. Now, to make this tick mandatory
This can be done through SPRO settings. Through tcode OIAL and Influencing > Notification Type (Value M2).
Set the VIQMEL-MSAUS field as Req as shown below.
After this, if someone un-ticks the Breakdown indicator and tries to Save the Order the following error appears in the status bar.
Once it is Ticked, the Order will be saved in the next attempt.
Hope this helps
