Property sheet for com.sap.security.core.ume.service set to final

Hi folks I need some help here,

In our PI 7.31 we don't have login for a user with administrative auth. so I need to activate the SAP* user. I have done this many times in other systems but this is different.

I did change it in globals->clusternode_config->workernode->services->com.sap.security.core.ume.service but it's not working as it seems that the efective template is ZATPL_AIO.

So I tryed to change it there

But I can not change the Property sheet for com.sap.security.core.ume.service as it is set to "final"

When I try to remowe the "final" I get the error:

Error: Error occurred: The ConfigEntry '#@ume.superadmin.activated' in configuration 'cluster_config/templates/default/Z

ATPL_AIO/cfg/services/com.sap.security.core.ume.service/properties' is final. No modify operations are allowed on inheri

ted final ConfigEntries!

How can I change that? Or what else can I do

Kindly regards

Torben
