How can we set-up allocation rules for specific gl accounts?

Hi

Our company has multiple divisions and operating units. We have multiple locations and multiple divisions and operating units share the locations. We want to allocate expense based on rules(% of land used). We are in E-Business Suites Core Modules only (General Ledger, Accounts Receivable, Accounts Payable, Procurement and Fixed Assets).

I would need some guidance on how to achieve this using general ledger and allocation worksheet, etc.

Thanks

Regards

Hari
