Field Validation for Authorization Object field on selection screen

Hi Experts,

We have included a new field u2018Authorization Objectu2019 in the selection screen which should be reflected in the field Authorization Object of the spool property. Please let us know how we can provide F4 help for this field and also validate it in the code.

The data element "RSPOAUTH" is used for the field on selection screen parameter. However, as there is no value table attached to the domain, we are unable to provide any F4 help and hence cannot validate the field in the code.

Looking forward for your valuable reply.

Thanks in advance.

--Warm Regards,

Prajakta Kanitkar.
