Extend the scope of number sequences

This article shows you how to extend the number sequence scope.

The scope of a number sequence defines which organization uses the number sequence. The scope can be Shared, Company, Legal entity, or Operating unit. Company and Legal entity scopes can be combined with fiscal calendar periods to create even more specific number sequences. New number sequence scopes can be added through extensions.

To create a new scope and have it show up in the client, complete the following steps:

1. Create an enum extension for NumberSeqParameterType. In the extension, add a new enum value for the new scope type.
2. Create an enum extension for NumberSequenceType. Add a new enum value for the new scope type. The NumberSequenceType enum is used in NumberSequenceTableEntity and NumberSequencesReferenceEntity.
3. Create a table extension for the NumberSequenceScope table. Add a new field for the new scope type.
4. Create an extension class for NumberSeqScope class.
   1. Create a post handler for the NumberSeqScope::getValidScopeTypes method. In the event handler method, add the new scope type to the valid scope types list.
   2. Create an event handler for the onGetFormatSegmentShortName delegate. In the event handler, return the short name for the new scope type.
   3. Create a post handler for the NumberSeqScope::find method and add logic for the new scope type so the corresponding NumberSeqScope instance can be found.
   4. Create a post handler for the NumberSeqScope::getId method and add logic for the new scope type, so the corresponding record can be found (or created if it does not exist) in the NumberSequenceScope table.
5. Create an extension class for the NumberSequenceScopeFactory class. Add a method that initializes the new NumberSeqScope that represents the new scope type.
6. Create a form extension for the NumberSequenceDetails form. Add controls that show the new scope type to the Scope tab.
7. Create an extension class for the NumberSequenceDetails form.
   1. Create a post handler for the updateScopeControlVisibility method to show the new scope type when the new scope type is selected in the Scope box.
   2. Create a post handler for the updateScopeControlValues method to update the values of the controls in the Scope tab.
   3. Create a post handler for the createScope method to initialize a NumberSeqScope instance when the new scope type is selected.
   4. Create an event handler for the getShortNameForParameterType delegate to return the short name for the new scope type.
8. Add an extension class for the NumberSequenceTableEntity and NumberSequencesReferenceEntity data entities. Create post handlers for the GenerateNumberSequenceScopeTypes and GenerateNumberSequenceScopeValues methods to generate the NumberSequenceScope for the new scope type.
