ip10 - Vendor blocked

Hi,

When trying to schedule the maintenance plan in IP10, it's showing that Vendor is blocked. How it's related to vendor when scheduling it. To my knowledge, whenever it's scheduled, a WO will be created on the scheduled date and that WO will create a PR which contains a vendor.

There is a material component allocated to task list for which system is giving error message u201CVendor xxxx blockedu201D.

Where this vendor detail is maintained for this task list or maintenance plan?

Thanks & Regards,

Manish
