To create a new user-defined export width definition, call the ReplaceExportDefinition stored procedure with the following arguments:
  • export_definition_name is a LATIN character string that specifies the name of the new export width definition.
  • export_width_rule_set is a BYTE string of 40 hexadecimal digits, which encode the export width rules for the new export width definition. For details about the export width rules, see “Export Width Rules”.
  • result_message is an output parameter that contains the output message of the stored procedure.

ReplaceExportDefinition creates the new export width definition with the specified rules and updates the DBC.ExportWidth table.

To modify the export width rules for an existing user-defined export width definition, call the ReplaceExportDefinition stored procedure with the following arguments:
  • export_definition_name is a LATIN character string that specifies the name of an existing user-defined export width definition that you want to modify.
  • export_width_rule_set is a BYTE string of 40 hexadecimal digits, which define the new export width rules for export_definition_name. For details about the export width rules, see Export Width Rules.
  • result_message is an output parameter that contains the output message of the stored procedure.

ReplaceExportDefinition modifies the specified export width definition with the new rules and updates the DBC.ExportWidth table. The revised export width definition takes effect at the next transaction for each affected user. In process transactions continue with the existing export width definition.

You cannot specify 'Expected', 'Compatibility', or 'Maximum' for export_definition_name.
