Hi Sunil,
It will not allow you to add the qualified lookup value in the main table record directly.
As the qualified lookup field in the mai table links the main table record with the qualified table fileds.
You will only be able to view the non-qualifier field values in the main table but the qualifier value for that particular record will be visible in the qualifier table only.
So as to populate the lookup qualifier you need to create the main rec then you can establish the link and populate the qualified table fields.
Hope it helps
Kindly reward points if found useful
Thanks
Simona
