Resolution

In this case there was a parent WO P- which covers a child PH- WO which covers a T- WO.  

In general, this is the procedure to follow:

1.  Create source system pointing to DB backup from closest point prior to the corruption.  
2.  Login to source system and use PRPC to create RAP for broken WO and its covered WO(s) only.  That is, if PH- level corrupt then include PH- and P- in RAP.  If P- corrupt only include P-.  If there was a T- corrupt then include T-, PH-, and P-.  In the source system create a new Product rule.  Under "Individual Instances to Include" list the pzInskey of the appropriate WOs, save the rule and then click on the "Create Product File" button to create the RAP file.
3.  In target system import the RAP file.  Cleanup any broken assignments and then progress WOs from restored state to point of failure using history audit trail.
