Create a ranges..

RANGES: r_value for int4.

r_value-sign = 'I'.

r_value-option = 'BT'.

r_value-low = '20'.

r_value-high = '40'.

append r_value.

if not v_value in r_value.

message e000.

endif.

IF v_value between 20 AND 40.

DO NOTHING..

ELSE.

MESSAGE E000.

ENDIF.

Thanks,

You can do it understanding this:

PAI: Process After input

PBO: Process Before output

Take a look

In your PAI module Flow logic

FIELD S_VAL module validate_sval.

in your PAI module pool.

module validate_sval.

if s_val < 20 or s_val > 40.

--error message.

endif.

endmodule.

Hi,

You have to code this in PAI.

PROCESS AFTER INPUT.

FIELD FIELD1 MODULE VALIDATE_FIELD1 ON INPUT.

Write your logic in the program to validate the FIELD1 like below.

MODULE MODULE VALIDATE_FIELD1 INPUT.

IF NOT FIELD1 BETWEEN 20 AND 40.

MESSAGE E398(00) WITH 'ERROR'.

ENDIF.

ENDMODULE.
