Add validations to the "validate response" process

Summary:

The standard functionality validate the supplier response using the "Validate Response" Scheduled process to inform the user errors during the data entry process. When there are errors in the supplier quotation, the process deploys pop-up messages. These messages can be created or updated using the task "Manager Messages."

We are required to add a custom validation to this process. The objective is to display a warning message before he summits it. In the event that the supplier uses a different response currency than the negotiation currency.

Has anyone tried something similar to this before?

Thanks in advance
