Thanks Pablo,
@zacrify - Yes, this template was created a while ago and needs updated to the latest published archetype versions. It was designed as an exemplar not as strictly deployable as local changes will always need to be made.
What you should do is to download the ePrescription template from CKM as a Template Fileset and import into Archetype Designer - I’d suggest you create a separate AD repo for this purpose. You can just drag/ drop the .zip file. This will contain the .oet and all of the archetype components.
You can use that as-is and it will work fine but it is generally best to use the latest archetype versions if you can.
Make sure that Enable updates is selected in AD settings. You will then see an Updates option on the top menu.
This will show a comparison of the versions on CKM versus what you have locally.
You can also use the Downloads tab to easily download other archetypes from CKM (or another source).
