Hi,

the F4 help only provides input help, but no input validation.

You probably want a conversion exit or an input validation in your report.

Conversion exit is a routine defined in the Definition of the domain.

You can convert from an internal representation to an external representation. But you could also write error messages, if the input is not valid.

If you only need validation and no conversion from internal to external representation, you can validate the input in PROCESS AFTER INPUT section of a dynpro. Or somewhere else in a report.

Regards

Christian

Hello,

Send to your parameter the option "AS LISTBOX...".

F1 on the PARAMETER keyword and you will see the syntax.

Best regards,

Paul.

Hi Yogesh,

Set a validation to your input field.

When user enters input, under AT-SELECTION-SCREEN event write the validation logic.

For eg: Select single <field_name>
from <DB_TABLE_NAME> into <lv_check> where <field> eq <input_field_name>.

IF sy-subrc <> 0.

Throw error message here.

Message e001 (00).

endif.
