How to stop navigation to work order creation page?

@Sono Chacko-Oracle

Summary:

Hi @Sono Chacko-Oracle @Edson Junior, Oracle could you please guide me to implement below use case?

Our requirement is that when the EBSSRContact_Id_c field is null in the service request, and a user clicks the Create Work Order hyperlink on the panel/smart action, they should see the following message:

“Onsite Contact on the Case Summary page must be entered before creating an SR.”

In this scenario, the Work Order creation page should not open. It should only open when EBSSRContact_Id_c is not null.

Currently, I have implemented the below logic in the vbEnter event listener of the Work Order creation page, but it still allows the user to access the Work Order page even when the contact field is null.
