Hello,

You can try this.

loop at itab <-----the table passed to table control

chain.

itab-tab_fld1.

itab-tab_fld2.

itab-tab_fld3.

module validate.

endchain.

endloop.

module validate input.

*do your validations for table control fields.

if sy-subrc <> 0.

loop at screen.

if screen-name = scrn_fld1.

screen-input = 1.

modify screen.

if screen-name = scrn_fld2.

screen-input =2.

modify screen.

endloop.

end module.

regards.

Hi Krishna,

Check the below syntax.

loop at it_valid.

chain.

it_valid-seld1.

it_valid-seld2.

it_valid-seld3.

module valid.

endchain.

endloop.

module valid input.

if sy-subrc <> 0.

loop at screen.

if screen-name = scrn_fld1.

screen-input = 1.

modify screen.

if screen-name = scrn_fld2.

screen-input =2.

modify screen.

endloop.

end module.

Cheers.
