Two level Approval WorkFlow

Question

Hi.
I have this problem:
Have two Approval WF which a re triggered deppending on the user type
The first WF is a one level approval WF, and work Very fine,
i'ts assigned to a group using an adaptor and when it's approved, the provisioning process is assigned to SYSTEM ADMINISTRATORS and executed success.
The second WF is a two level (secuential) WF, also is assigned to a group using an adapter and when first level is approved, the Second level task is executed (also assigned to a group via adapter), but when the second level task is approved, the provisioning task is assigned to the same user which approved the second level and the provisioning process involves add/delete values from a lookup, then I receive an "ACCESS DENIED" error.
I've been thinking about adding a third level and assign it to XELSYSADM, but think that is not a pretty standard solution.
a way to draw the second WF is:
task 1 Response = Approved then execute Task 2
Am I missing something?
Should I use Task Dependency instead Executing the second task basen on the first Task Response ?
Thank You.

Answer 1

That's correct.
The first approval level appears to be finished by XELSYSADM even if its approved by another person (ie: User1)
The second approval level appears to be finished by "User1", but User1 can be one of aproximately 50 people, and do not want to give object write access to so many.
So opted for add a third level of approval and add a TCCompleteTask and assign it to XELSYSADM.
So XELSYSADM now executes all the Provisioning process .
Thank You Very Much.
