Compatibility at Runtime

To some extent, the Business Object Layer (BOL), which is the business object runtime based on the BOR is compatible with the business object runtime as generated from the LN Studio.

However, migration to the LN Studio cannot always be done without any impact on the interface at runtime. For example:

• As mentioned in After the Import, some interfaces allowed in the BOR cannot be defined using the LN Studio.
• Event publishing functions have changed. In Enterprise Server 8.2, PublishChanges, UnpublishChanges and PublishList were used. These functions can still be used. But if the business object is migrated from the BOR to the LN Studio, the new functions (SubscribeEvent, UnsubscribeEvent, SubscribeList, and PublishEvent) must be used.
