If you use alternative labels for SAP Functional Locations then be aware that the change program SAP uses to execute updates (in core SAP) does not trigger the Functional Location change event. Since that event is used to update BlueWorx, changes to alternative labels will not be promulgated to the device unless either:

1. Another change is made the does trigger the update event, or;

2. You refresh the Functional Location master data - see job #4 here: Master Data Tables and Batch Jobs
