validating custom enhanced fields for wbs elements in cj20n

[Former Member]

Hi,

I am validating custom enhanced fields for wbs elements in cj20n.

when i show error after a wrong value entered the screen is locked and i can't proceed for saving new values i.e it is not even allowing saving of values.

What i wanted was after user enters wrong value the field should remain active and take new values provided by f4 help and save it.

DATA : it_proj_typ TYPE TABLE OF zps_proj_typ.

SELECT * FROM zps_proj_typ INTO TABLE it_proj_typ WHERE zptp =

prps-zzptp.



  IF sy-subrc NE 0.

    LOOP AT SCREEN.



      IF screen-name = 'PRPS-ZZPTP'.



        screen-active = 1.

        screen-input = 1.

        screen-output = 1.

        MODIFY SCREEN.

      ENDIF.





    ENDLOOP.

*message text-001 type 'E'.

Also , i WOULD LIKE TO MENTION CHAIN END CHAIN IS NOT WORKING.

Use

Field <field_name> Module <Module_name>.

within PAI of the screen. Give Error message in case validation fails.

i have already tried  it.

It's not working

It has to. You might have done something wrong. Chain-Endchain is not a sytax for it.

Post a screenshot of your coding if possible.

Hi,

Did you try in debug mode whether screen names are correct?

Hi ,

I could Finally solve the problem and get the output but still i don't know the exact reason for it.

What i did was change screen-input and screen-output values to 0 and it was working.

AND STILL VALIDATION THROUGH FIELD <FIELDNAME> MODULE <MODULENAME> IS NOT WORKING.

I still don't know why  it is not going to that part itself as i tried keeping  hard coded breakpoint in that but it never went to that break point.
