3147565 - Releasing project billing results in an error and failure to create the billing request

Releasing a project billing through 'Manage Project Billing' results in error message:

• In activity & the plant for material & is missing.

OR

• Creation of the billing document request failed.
  BDR with preceding document has not been created due to item errors.

• Sales and Distribution (SD)
• Professional Services (PS)
• SAP S/4HANA Cloud All versions 

The error is raised because the sales order service (SO01) has been created without a plant at line item level.

• The Delivery Plant needs to be maintained in Manage Product Master Data for the Billing Item Product(s) so that it will be automatically determined during sales order processing.
• For the existing sales order item, the item needs to be rejected using app 'F0804' Manage Sales Order Services and a new billing item should be created with the Plant data filled.
• To keep the old work package - Create a dummy work package and assign it to the existing billing item - now the WP that you want to keep is unassigned. Reject the sales order item as mentioned previously - Create a new billing item and assign the old work package to it - now you have a new billing item with the old work package.
