What is the MultiOrg and what is it used for?
MultiOrg or Multiple Organizations Architecture allows multiple operating units and their relationships to be defined within a single installation of Oracle Applications. This keeps each operating unit’s transaction data separate and secure. Further all organizations can share some master data like supplier, customer, bank, AFF, payment terms, price lists etc.
Use the following query to determine if MuliOrg is intalled:
select multi_org_flag from fnd_product_groups;
