Hi,

First create your first screen say 100.

In that screen 100 write ur select satetment in PBO.

select * from MARA into corresponding fields of table i_mara where matnr = mara-matnr.

When u enter matnr in input field all the remaining 3 fields value must be diplayed..

For that place a button in that screen 100 called "Enter".

and in the PAI event of screen 100 write.....

case sy-ucomm.

when ENTER(function code of that button).

display ur 3 fileds meins mtart maktx based on matnr..

.

.

..

.

.

endcase.

for F4 help on matnr use the foll function module...

MODULE value_carrier INPUT.

CALL FUNCTION 'F4IF_FIELD_VALUE_REQUEST'

EXPORTING

tabname = 'DEMOF4HELP'

fieldname = 'matnr'

dynpprog = progname

dynpnr = dynnum

dynprofield = 'matnr'.

ENDMODULE.

You can use the commands SET/GET PARAMETER 'MAT'

it's use for data element matnr.

SET PARAMETER ID 'MAT' FIELD field.

GET PARAMETER ID 'MAT' ID field.
