This activity is used to indicate that the sub contract revision is undergoing
an approval process. The status of the revision will be changed to Approval
In Progress to indicate that it is currently undergoing approval.
Modifications to the sub contract revision lines or items will not be allowed
when the revision is undergoing approval, unless the Update Allowed During
Approval toggle is selected on the sub contract revision. The purpose of
this feature is to avoid changes being made to the sub contract revision after
it has been approved by someone else. If changes are required, the sub contract
revision must be set back to the Planned status by canceling the approval.
The sub contract revision must be in the Planned status.
The sub contract revision is set to the Approval In Progress status.
