Dynamic catalogs are introduced with version 2021 Summer at the latest. Beginning with 2021 Summer Alpha2, the Web-API Gateway offers the endpoints for maintaining such catalogs, and the users are offered a pick-up list including an edit dialog if the property readonly is not set.
These catalogs are named dynamic because they can be changed by responsible users without changing the schema configuration.
In the following, the different use of such dynamic catalogs is described.
Dynamic catalogs used by a specific tenant
If only a specific tenant will use a dynamic catalog it is recommended to configure this catalog with a classification-tag for the field that should contain one of its values:
<propertyStringDefinition> <id>contract</id> <propertyType>string</propertyType> <cardinality>single</cardinality> <required>false</required> <classification>dynamic:catalog[appMytenant:contracts]</classification> </propertyStringDefinition>
After uploading the tenant-schema 'Mytenant' the user will get an empty pick-list for that field. A user with the role YUUVIS_MANAG_SETTINGS can maintain this list:
- Create a new list element
- Remove a list element. A warning is given if this element is used by an object.
- Disable a list element. Such elements are offered for search but not during creating or editing an object.
An administrator with the role YUUVIS_TENANT_ADMIN can maintain the dynamic catalog contracts using the Web-API Gateway GET and POST endpoints https://<domain>/api-web/admin/catalogs/tenMytenant:contracts of the admin-controller.
The catalog data is saved in the config server beside the tenant-schema configuration.
The format of the catalogs is JSON. The following example shows a list of two elements stored for the tenant Mytenant:
{ "tenant": "Mytenant", "entries": [ { "name": "Contract 1", "disabled": false }, { "name": "Contract 2", "disabled": false } ] }
The client uses the Web-API Gateway dms-controller endpoints:
- The list elements from the catalog are read with the GET endpoint https://<domain>/api-web/dms/catalogs/tenMytenant:contracts
- If the catalog does not exist it is created with the POST endpoint https://<domain>/api-web/dms/catalogs/tenMytenant:contracts.
- If the catalog does exist changes of its list elements are saved with the PATCH endpoint https://<domain>/api-web/dms/catalogs/tenMytenant:contracts.
Set a catalog to read-only
If a catalog should be stable after setting it up, the parameter readonly can be set into the classification-tag, e.g.:
<classification>dynamic:catalog[appMytenant:contracts,readonly]</classification>
Global dynamic catalogs used by all tenants
In this case, your tenants should use object types that are configured in a system or app-schema and should use only standard values an administrator with the role YUUVIS_SYSTEM_INTEGRATOR can set up global catalogs with initial standard elements and set the catalogs readonly. In this case the Web-API Gateway system-controller endpoints GET and POST are used.
- For the catalog contracts in the system-schema: https://<domain>/api-web/system/catalogs/contracts
- For the catalog contracts in the app-schema businesspartner: https://<domain>/api-web/system/catalogs/contracts?appschemaname=businesspartner
Global catalogs without an appschemaname are saved in the config-service beside the system-schema configuration. Otherwise the catalogs are saved beside the app-schema configurations.
Editable global catalogs
If the catalog parameter readonly is not set users with the role YUUVIS_MANAGE_SETTINGS can change the list elements. With the first update of such a catalog, a new catalog with the same technical name is saved for that tenant.
Note: From now on changes made in the global catalog are not affecting the copy. Only new tenants will get the new list elements of the global catalog.
