Hi, normal practice would be 2 after update BR's, one for cmdb_ci_server and one for your location table.
If the Br's are making exactly the same update, you may be able to create 1 script-include function and then call it from the 2 separate BR's. If an async update was acceptable another option would be to trigger sysevents from the BR's and and then consume them in a script-action.
