Consider: we have request which is in Approval process and waiting for the Approval from Approver1. 

Now if Approver1 is absent, a new Approver (Approver2) should be able to re-assign the Approval ability to himself and should approve it.  But When Approver2 tried to update the ProcessInstanceWorkItem object to re-assign the Approval ability to himself (designed with a help of customisation), receiving an error as follows: 
“INSUFFICIENT_ACCESS_ON_CROSS_REFERENCE_ENTITY, insufficient access rights on cross-reference id: []”

Please help me to resolve this issue.

We implemented an approval workflow and also approval escalation when initial approver did not respond within 24 hour. However, when we tried to UPDATE the ACTORID for the processinstanceworkitem, we received this error:

 

INSUFFICIENT_ACCESS_ON_CROSS_REFERENCE_ENTITY

 

what permission do we need for the user to be able to update the processinstanceworkitem?

 

Thanks.
