Data Item Name for an External Data Dictionary Item
When you create an external data item, you must use a Y or Z in the first character of the data item name to distinguish an external data dictionary item from a JD Edwards EnterpriseOne data dictionary item.
The data item name can be a maximum of 32 alphanumeric characters, and adheres to this format:
Ysssdddddddddddddddddddddddddddd, where:
Y or Z = The first digit of any JD Edwards EnterpriseOne system-assigned external system code. This character indicates that the data dictionary item is external.
sss = The system code number, which is 55x-59x for enterprise-level development of new modules, or 60x-69x for custom development of a JD Edwards EnterpriseOne system.
ddddddddddddddddddddddddddddd = The name of the data item.
