Control Table Rules
An update merges your control tables during an update using the Change Table process, a delta between the base product and the update, as the basis to do the data merge.
An update preserves these changes:
Data dictionary custom changes, such as changes to row, column, and glossary text. The update process uses your data dictionary as the base. If there is a conflict with JD Edwards EnterpriseOne data items, your changes override them.
User-defined codes. The update process merges any new hard-coded JD Edwards EnterpriseOne values. (Values owned by JD Edwards EnterpriseOne are system 90 and higher, and H90 and higher.) The process also reports any JD Edwards EnterpriseOne hard-coded values that conflict with your custom values.
Oracle's JD Edwards EnterpriseOne Workflow. The update process merges any JD Edwards EnterpriseOne additions, updates, or deleted workflow processes in your data. If there is a conflict with your workflow processes, JD Edwards EnterpriseOne overrides them.
