The database view that the Asset Tag label uses has the Location description, but omits the Location code, and has the Site name, but not the Site description.
To add these missing items to the label, first make a database backup, then download and extract https://dl.waspbarcode.com/kb/ma/v7/Asset7LabelView.zip on the server machine. Run FixAssetTagLabelView.bat to update the database view. The batch file will not run properly from within the zip file. The files must be extracted first.
After running the batch file, reopen the label, and the data table will now include 2 additional columns: sitedesc is the Site description, and location_code for the Location code.
