Are you using chain. endchain. with the field you want to have the end user fill in:

For example:

Chain.

field: field1, field2, field3.

module error_check.

endchain.

Hi,

You can do it using CHAIN...ENDCHAIN.

In the main screen flow logic,

PROCESS BEFORE OUTPUT.
 MODULE STATUS_1000.

PROCESS AFTER INPUT.
 CHAIN.
  FIELD : field1 MODULE check-field1,
              field2 MODULE check-field2,
              field3 MODULE check-field3.
 ENDCHAIN.

Now write the code for these modules in F01 include.

MODULE check-field1 INPUT.

  SELECT SINGLE field1
    FROM ztable
    INTO lv_field1
    WHERE field1 = ztable-field1.

  IF sy-subrc = 0.
    MESSAGE 'field1 already exists' TYPE 'E'.
  ENDIF.

ENDMODULE.                 " check-field1 INPUT

Hope it helps you.

Thanks,

Sri.

Hi Srihari,

In this case follow the following code,

PROCESS AFTER INPUT.

CHAIN.

FIELD: FIELD_01 MODULE CHECK_FIELD_01,

FIELD_02 MODULE CHECK_FIELD_02,

FIELD_03 MODULE CHECK_FIELD_03,

FIELD_04 MODULE CHECK_FIELD_04.

ENDCHAIN.

Write your validations for the screen FIELD_01 in the MODULE CHECK_FIELD_01

so when you enter data in this field it enters this Module and checks the validations, if value passes the validation then the cursor moves to the next field (i.e. Field_02) otherwise if it fails the validation & you have specified the message type as 'E' then it waits on the same field of the screen till a correct value is entered.

Hope it helps you,
