How to import a bpc (Boyum Configuration Package) file:
Bcp files are files containing one or more configurations for B1 Usability Package + any metadata the configurations might need (Usertables, fields etc.)
In order to inport a bcp file you will need to run B1UP 5.0 or higher. Once the addon is running navigate to Administration > Add-ons > B1 Usability Package > Mass import. On the mass import window click on the '...' at the upper right to select the bcp file. Once selected the screen will display information about the package contenct (information about creator and the configurations in the package)
After you confirm the data and selected your option press the import button and the selected data will import.
