After Showing ERROR message make the field editable in subscreen.

Question

Hello Experts,
I have a requirment where i have added a subscreen to the standard screen of ME31K for creating the contract. In my Subcreen i have my custom screen fields that i'm updating in EKKO table through include structure.
Now if user forget to fill the details in my custom fields in the subscreen then i'm giving the error message prompting the user to fill the value in fields.
But the problem is the screen is locked there itself i want to make the field editable so that user can enter some value in the fields. I can not use the stuatus or information message here because doing this i will get the item overview screen which should not come as i want to restrict the user to header details only and fill all the custom fields.
Please provide me with your helpful responses.
Thnaks,
Naveen

Hi Naveen,
Sorry for the delay.
The code which I gave for popup, i hope its being shown in an IF . . . ENDIF.
So in that condition u can add the following :
IF < ur condition >
   < Call message FMs >
    SET SCREEN SY-DYNNR.   "this would set screen to current screen which is 0201
    EXIT.
ENDIF.
Other than this if you like you can set some parameters in the PAI of this screen which redirect to current screen based on some conditions.
So u can manually set OK-CODE and CALFCODE as SPACE, but i dont know how much this can impact the process.
So please follow the above code.
This is available in
Main Program     SAPMM06E
Source code of   MM06EF0F_FCODE_CALL
IF OK-CODE EQ SPACE AND
   CALFCODE EQ SPACE.
  SET SCREEN SY-DYNNR.
  EXIT.
ENDIF.
Hope this helps.
