Fields | Description
Company | The number of the ERP LN company containing the business object that provides the event publishing service. Allowed values The company number is mandatory and must be a whole number in the range from 0 to 999.
Business Object Name | The name of the business object that provides the event publishing service, for example SalesOrder. The subscription will be created for this business object. Allowed values This field is mandatory. To specify a value, zoom to the Business Objects (ttadv7501m000) session and select in this session a business object. This session only shows the public business objects of the current VRC. To specify a private business object, enter the name of the business object directly in the field. The Business Objects (ttadv7501m000) session can contain business objects that are not suited for event publishing, because they do not have a SubscribeEvent and a PublishEvent method.
Select Standard Event Actions | If this check box is selected, the subscription uses all standard event actions of the selected business object. These standard or default event actions are the standard events according to the BDE specification (that is, create, change and delete) (see Event Actions). Default value By default, the check box is selected.
Event Actions | The actions that can be performed on the selected business object and that trigger an event. These actions can include standard event actions or custom event actions. The standard event actions consist of the invocation of standard methods Create, Change and Delete, as explained in the following paragraphs. For the BDE Business Interfaces changes in the state of a business object instance produce events by default. These changes are referred to as standard event actions and correspond to the standard business object methods `create`, `change` and `delete`. Allowed values A list of one or more event actions for the selected business object. The event action names must be separated by spaces. You must select at least one event action. The default event actions are: `create` `change` `delete` Note that these event action values are case-sensitive.
Select All Attributes | If this check box is selected, the published event messages will contain data from all components and attributes of the selected business object. Which business data is published will depend on the selected business object. Default value By default, the check box is selected.
Component/Attribute Selection | The business data (components and attributes) that are included in the published event messages. Allowed values A list of one or more attributes or components of the selected business object. The attribute or component names must be separated by spaces or new line characters. You must select at least one attribute. The selections are the same as the ‘selectionAttribute’ contents in the BDE List and Show methods. Therefore, you can use <Component>.<Attribute> or <Component>.<Group>.<Attribute>, or you can use a ‘*’ to select multiple attributes from the same component or attribute group. The following values illustrate how you can specify a selection: `Order.date` (only the order date) `Order.Line.PriceData.*` (the complete contents of the PriceData group in the Line component) `Order.*` (all attributes from the Order component, but the Line subcomponent will not be included) Note If at least one attribute is selected, then the identifiers from the component and its parent components are also selected. For example, if you select `Order.Line.Item`, then also `Order.Line.LineNumber` and `Order.OrderNumber` are selected.
Select All Instances | If this check box is selected, no filter is applied and the specified business object publishes event messages for all its instances. Default value By default, the check box is selected.
