Epicor provides various licenses for Kinetic. Here is an example from Jose of all that are available:
The most expensive license is the Default/Office license. It can do everything. The web service license is the next one that can do anything. The last time I purchased one, the first three were only slightly less expensive than an Default/Office license. After that however, they got much cheaper. A Web Service license is throttled so you can’t just buy one and expenct to run all your users on it. Details elsewhere on the forum. The Data Collection license is the least expensive, but the command set is limited to only what you can do in MES.
