Partner of partner function SLFN0003 could not be changed

Question

Hello,
I want to resolve the Support Team by Category instead of SAP Component.
The Support Team is determined by the Rule AC13200137 and uses the
Category instead of SAP Component to determine the correct Support
Team (SLFN0003).
I've tested the rule and agents are resolved correctly
according to Category.
When the a service record is created the initial resolution for the
Support team is successful based upon Category.
However, when the Category is changed after the Support Team has been determined, the Support Team cannot be updated when the document is SAVED. In the Transaction Data -> Action ->
Process logs displays the following error:
Date: 13.02.2008 Time: 16:44:59
Processing CRM_DNO_PARTNER_1 Is Started
Partner of partner function SLFN0003 could not be changed here
Action could not be successfully executed
Analysis:
When the Support Team field on the CRM_HEADER is NOT empty the resolution by Category cannot update the Support Team field.
The workaround when a Category has been changed is to clear the Support Team field then SAVE then the Support Team is resolved correctly to reflect Category changes.
Is there a method to FORCED the overwrite the Support Team field when the
Category is changed?
Please advise.
Regards,
Latief

Hi Raquel,
Thank you very much for your quick response. Unfortunately, I had to wait for an ABAP'er  to make the necessary changes. Your feedback was helpful and points have been allocated accordingly.
Below is an extract of the code applied to the functional module "CRM_DNO_UPDATE_PARTNER" to allow overwriting the Support Team field when already determined and the CATEGORY field has been changed.
