Hi,

I have custom module pool with 5 screens. The fields displayed in the screen are from table MARA.

and also i have custom table with following fields

MATERIAL TYPE

FIELD NAME

FIELD NAME1

while user press SAVE button, then i need to validate screen field from module pool with above mentioned table.

ie in screen i have field MDESC with material type 01, in the custom table i have an entry like this way

01 MDESC

then the screen field MDESC in module pool is mandatory.

How to do this? This validation need to done only on SAVE

HI,

Try this logic..

IN PAI...

If sy-ucomm = 'OSAV'.

Chain.

do ur validation on screen.

check for ur fields.

if mtype = '01'.

if mdesc is initial.

message: 'Field is mandatory'.

endif.

Endchain.

Endif.

LOOP AT SCREEN.
  SELECT SINGLE * FROM ZTABLE WHERE MATERIAL_TYPE = <....>
                                                            AND FIELDNAME = SCREEN-FIELD.
  IF SY-SUBRC = 0.
* --> DO your validation
  ENDIF.
ENDLOOP.

Naren,

In my custom table i have only material type and fieldname. Actually my requirement is if the screen field is not filled then system should check the custom table whether the fieldname is found, then that field in the screen is mandatory.

Thanks

Hi,

Okay...I have assumed that for material type 01 you will have more than one field that requires to be mandatory..

Check this..

Create a module in PAI..

MODULE USER_COMMAND INPUT.

CASE sy-ucomm.

WHEN 'SAVE'. " Function code for save..

* Get the values from the custom table ZTABLE and move it to the internal table

T_ZTABLE

SELECT * FROM ZTABLE

INTO TABLE T_ZTABLE

WHERE MATERIAL_TYPE = '01'. " I am assuming 01

* Process the records.

LOOP AT T_ZTABLE.

* Get the field value dynamically

ASSIGN (T_ZTABLE-FIELDNAME) TO <FS>.

CHECK sy-subrc = 0.

IF <FS> IS INITIAL.

* Error message..the field is mandatory.

MESSAGE E208(00) WITH T_ZTABLE-FIELDNAME ' Is required'.

ENDIF.

ENDLOOP.

ENDMODULE.

Hope this helps.

Thanks,

Naren
