@SelengulH7653 please can you clarify - is this a question about the functionality within the My Support Portal?

If so can you please first consult the MSP FAQ page and How to Get Support page?

Or is this a question relating to a PDC deployment ticket?  Please check the Pega Predictive Diagnostic Cloud FAQ.

Check if issue is due to not being correctly affiliated to the companies or given correct MSP roles.

You need to be affiliated with both accounts in MSP and listed as a support contact.

This is all documented in the main Pega Predictive Diagnostic Cloud
