first the user enters the plant (input button).

Now i have a table control where the user has to enter the material no.

Now my requirenment is that as soon as the user enter the material no. it should check that the material should be extended in plant.

if nt than a error msg shuld be displayed.

thanks in advance,

Hi,

You can write a Chain endchain command in the correponding PAI and validate it.

ie,

in PAI.

LOOP at Itab.(Which is used for table cntrol).

chain. "ISBN-Nr.

field: <MATNR> '' The field for matnr in Table control.

module validate.

endchain.

endloop.

"And in module.

MODULE validate.

select single <matnr> from marc

into <wa-marc>

where matnr = <matnr> and

werks = <werks>.

if sy-subrc ne 0.

<error message>

endif.

where

ENDMODULE.
