Understanding Business Functions

You can use business functions to enhance JD Edwards EnterpriseOne applications by grouping related business logic. Journal Entry Transactions, Calculating Depreciation, and Sales Order Transactions are examples of business functions.

You can create business functions using one of these methods:

• Event rules scripting language.

  The business functions that you create using the event rules scripting language are referred to as Business Function Event Rules (also called Named Event Rules (NERs)). If possible, use NERs for the business functions. In some instances, C business functions might better suit your needs.

• C programming code.

  JD Edwards EnterpriseOne software creates a shell into which you insert logic using C. You use C business functions mainly for caching, but they can also be used for these objects:

  • Batch error level messaging.

  • Large functions.

    C business functions work better for large functions (as determined by the group). If you have a large function, you can break the code up into smaller individual functions and call them from the larger function.

  • Functions for which performance is critical.

  • Complex select statements.

After you create business functions, you can attach them to JD Edwards EnterpriseOne applications to provide additional power, flexibility, and control. You can attach tables and functions to a business function. You must add related tables and functions to the business function object to generate the code for the source and header files. Because the source code for NERs is generated into C, you use the same procedures for debugging both C and NERs.
