Subscreen validations.

[Former Member]

Dear friends,

I want to validate the sub-screen field.

from my main screen I am calling subscree which is having the dynamic select option.

I want to validate the subscreen select option field.

my code is like this:

PROCESS BEFORE OUTPUT.

CALL SUBSCREEN: MATKL INCLUDING SY-REPID '3000'.

PROCESS AFTER INPUT.

CALL SUBSCREEN: MATKL.

MODULE USER_COMMAND_0200.

Under USER_COMMAND_0200 I have writen the validation code:

SELECT * FROM zmmsortseq INTO TABLE itab_mfg

WHERE matkl IN r_matkl.

IF sy-subrc NE 0.

MESSAGE e000(zm) WITH text-010.

ENDIF.

r_matkl is my subscreen select option.

One the error message will triger I want to enable the select option again but its displaying in grey mode.

Thanks,

Hi Sridhar,

Give like this

IF sy-subrc NE 0.

MESSAGE <b>i000</b>(zm) WITH text-010.

ENDIF.

instead of e in the message give i then you will get it in change mode.

u cannot use select * for field validation .......

try using select single.............

SELECT single matkl FROM zmmsortseq INTO <variable of type matkl>

WHERE matkl IN r_matkl.
