Hi Krishna

Please dont use urgent. Every one is contributing voluntarily. If you had look at the function module in the exit it has a parameter I_TRTYP which identifies whether you are in create/change/display mode. Based on this mode you can disbale your field using loop at screen. screen-input = 0. modify screen

how are you reading data from SAP standard by exporting it in this exit..if yes then export this also. In PBO of your screen put a loop at screen and set scrren-input as 0

Use it in PBO modules, they are processed before output screen is displayed.

in the import part of your exit try this code

IF TCODE = 'ME23N'.

LOOP AT SCREEN.

SCREEN-INPUT = 0.

MODIFY SCREEN.

ENDLOOP.

ENDIF.

As nabheet madan wrote use I_TRTYP

In the PBO FM exit which receive this data, store it in global data include of the exit function group / Don't check sy-tcode which can be wrong
In a module of the PBO of your customer screen, use the saved fata in a LOOP AT/MODIFY SCREEN to clear SCREEN-INPUT field

Sorry, bad idea... Try to execute transaction 'ME23N' and press F7, you are in update mode with transaction code SY-TCODE = 'ME23N'.

i do not know how I_TRTYP works but if he do it with I_TRTYP will it work only in ME23N or for all ?

because he wants to make it display only in ME23N not others. it will still be editable in ME21N.

In almost every screen exit for customer fields this field is provided, its value define (in german) the type of transaction, also developer should always read enhancement documentation (SMOD, SE18, SPRO) before posting


In the header modules, you obtain the SAP transaction category via the
parameter I_TRTYP:
o   A   Display (Anzeigen)
o   V   Change
o   H   Create

As I wrote, did you save the received TRTYP in global area (ZXM06TOP ?) so every FM exit and module will be able to read it ?

As a rule save this kind of parameter in the global area of the function group which contains the exit FM, also save the data to be displayed on customer screen in work area defined with the TABLES statement (only suitable usage of this statement today)
