Specification Table Merges
You can use the upgrade process to merge custom modifications with JD Edwards EnterpriseOne applications. A single batch application merges changes to these objects:
Tables
Business views
Data structures (only new are added)
Interactive applications (no changes are merge, just new objects are added)
Batch applications
Business functions (only new are added)
See Modifications Rules in the JD Edwards EnterpriseOne Tools Package Management Guide for information about changes that merge or overlay former data.
