If users can't use the extension, they probably have not been assigned the permission set(s) required to enable them to use the extension.
Find here how to do this and which permission set is required.
During installation, from release 5.2.202410NN.0 on, the question will be asked if the USE permission has to be set to every user.
To Remove, Copy, or Replace the Assigned Permission Set(s) to all Security Lines, this can be performed with one action by selecting the value in a cell of a Linked Permission Set.
Use the options (AssistEdit button) in the menu on page Permission Sets per Field Security.
Choose what has to be done:
- Delete the selected sets from that column
- Remove the selected sets from all Security Lines
- Copy the selected sets to all Security Lines
- Replace the selected sets to all Security Lines

In a Field or Filter Security, click on the “Expand Factbox pane” in the top right corner.
This will show the permission sets which are assigned to the selected line.

Most system tables are not accessible for the Field and Filter security, because Microsoft has shielded these system tables from programming, to prevent errors when logging in.
A trial can be turned into a license by going to the Field Security Setup, Field Validation Setup and/or Inventory Reconciliation Setup in Business Central.
In the top of the screen, find the button “Request License”. Click this button to apply for a license. The registration details will show up which have to be completed, should some details be missing. After completing the details, click on the button “Confirm and request license”.
After completing the registration, a mail will be sent and the license will be matched to your account.
When our extension has been installed in a new environment, it is also required to register first after installation in this new environment.
Go to the Setup page of that extension and use the “Register” option in the top bar.

After filling in and sending your details, an acknowledgement will be received that registration has been successful.
The administration at 2-Controlware will receive this registration and matches it with a (valid) license.
The matching of the registration with the license will usually be processed within 48 hours.
Before the extensions can be used, the app(s) first have to be registered. This is required for each app and database separately.
Once registered, the 2-Controlware administration will receive a notification and will check if a valid contract is applicable. If so the license usually will be activated within 48hrs after registration. In the meantime a 30 day trial will start.
