What is the difference between Organization_Id and Org_Id?


Organization_Id represents Inventory Organization Id.
Org_Id represents Operating Unit Id.

A Global Variable exists in the Oracle Database called CLIENT_INFO, which is 64 byte long. First 10 Bytes are used to store Operating Unit ID(or ORG_ID) 
for the multiple organization support feature. 

Multi-Org views are partitioned by ORG_ID. The ORG_ID value is stored in 
CLIENT_INFO variable. (It comes in AP, PO, AR and OM Levels).
 
ORGANIZATION_ID is for inventory, Mfg and BOM.
