License Entitlement
A licensed product includes one or more entitlements. Typically, each entitlement represents a license agreement associated with the licensed product. For example, if ProductA is your licensed product, you might have an OEM entitlement to represent your ProductA licenses obtained through OEM agreements. You might also have a Per-Installation entitlement that represents ProductA licenses obtained through a site agreement.
The License Entitlement panel lets you to add the catalog product to an entitlement. The catalog product’s licenses are added to the entitlement and are consumed by installations that meet the entitlement’s scope (computer, user, enterprise, department, or so forth).
In the field, select the entitlement for the catalog product.
