RE: in CRM Online The '+' add record button on subgrids no longer loads option to an add existing record, it now only loads the quick create form to create a new record?
Hi Razwan,
It is usually because you set the lookup field to Required Field
For example:
Account and Product, have 1 : N Relationship.
Then in the Account you put Product subgrid, it will have + button to add new Product related to the Account.
But, in the Product entity, you set the Lookup field to Account, for example: new_accountid field to Required.
By design, it will open new pop up, if you allow quick create form, which is it will open Quick Create Form, instead. It will not open add existing.
Hope it helps!
Thanks.
