Not able to schedule task to supplier contacts using Third Party Portal

Hi,

I did all required setups in our R12.1.3 instance and able to schedule a task to TPO(Third Party Org)

1.      Defined a supplier contact with technician role.(after creating supplier contact and imported as CRM resource etc, added to calendar,territory)

2.      Created a Resource Group(TPO)

3.      Added these to calendar, territory.

4.      Ran STAR and Generate field Trip con etc.

5.      Created SR and assigned to TPO using scheduler.

6.      Once I login to TPO , I don’t see supplier contact so not able to assign to supplier contact of TPO.

 

I did lot of research on oracle metalink to trouble shoot but no luck. Any help is highly appreciated.
