Grayout input field based on condition in FPM GUIBB

[former_member231368]

Hi All,

Presently I working on Floorplan Manager for SAP EHSM module. I am new to this & having some technical challenges.

Requirements:

1. I have added a custom field to the screen and the same needs to be gray out/diplay mode based on some condition. I am able to see the filed on the screen updating the value into corresponding tables without writing any code since added this into BO structures.

Now challenge is I am unable to gray our the field. I wrote the code in FEEDER CLASS OF

     GET_DEFINITION   - Actions

     PROCESS_EVENT - Errors to be displayed if field value is not correct

     GET_DATA              - Making field in gray our or display. But it is not working as expected. Kindly do let me know whether the code is in right place or not.

2.  I am populating error message if the entered value is worng. But it is allowing to save and value is also updating.

Kindly help on this.

Thanks,

Yerukala Setty

FYI...

field-symbols: <fs_FPMGB_S_FIELDUSAGE> type FPMGB_S_FIELDUSAGE,
<lv_field>   TYPE any.

LOOP AT ct_field_usage assigning <fs_FPMGB_S_FIELDUSAGE> WHERE name EQ  'ZZEHSM_LEVELS'.

ASSIGN COMPONENT 'ZZEHSM_NEW_NR' OF STRUCTURE cs_data TO <ls_nr_id>.
ASSIGN COMPONENT 'ZZEHSM_LEVELS' OF STRUCTURE cs_data TO <lv_field>.
SELECT SINGLE *
FROM ehhssd_inc_binfa
INTO wa_ehhssd_inc_binfa
WHERE zzehsm_new_nr = <ls_nr_id>.

IF NOT wa_ehhssd_inc_binfa-zzehsm_levels IS INITIAL.
<fs_FPMGB_S_FIELDUSAGE>-read_only = abap_true.
ev_field_usage_changed = abap_true.
ENDIF.

endloop.
