Condition in Approval Procedure Rule in ChaRM not working properly

Hi experts,

We are on 7.1 SP8.

We have Z-partners defined and included those in the Approval Procedure too. In order to fill the approval procedure steps with the default partner, we defined a rule policy.

For example step ZMCR000001 needs to be filled with BPE by default.

This works fine.

But when we want to overwrite the default value with another value, the default is always put back over the manual entered value.

Also manually added process steps get that same value.

It looks as if the last step of the condition is not working properly (i.e. the check to see if the approver is already filled).

Can somebody tell me how we can get manually entered values in there?
