Using Text Substitution to Display Specific Error Messages

You can use the JD Edwards EnterpriseOne text substitution APIs for returning error messages within a business function. Text substitution is a flexible method for displaying a specific error message.

Text substitution is accomplished through the data dictionary. To use text substitution, you first must set up a data dictionary item that defines text substitution for the specific error message. A selection of error messages for JDB and JDE Cache have already been created and are listed in this chapter.

Error messages for cache and tables are critical in a configurable network computing (CNC) architecture. C programmers must set the appropriate error message when working with tables or cache APIs.

JDB API errors should substitute the name of the file against which the API failed. JDE cache API errors should substitute the name of the cache for which the API failed.

When calling errors that use text substitution, you must:

  • Load a data structure with the information you want to substitute in the error message.

  • Call jdeErrorSet to set the error.
