MessageSelector
The jobstep MessageSelector selects messages, which property according to gem. Function arguments1).
| Name | Meaning |
|---|---|
| Type | Type of the job step. |
| Name | Name of the job step that will appear in the job designer |
| Description | Optional description for the job step. |
| Expression | Function whose result returns true or false. All messages on which the function applies are selected from the incoming message box (Inbox, SelectionBase / InputMessages).The message structure (SelectionBase) is often required to formulate conditions. |
| Log XPath calls | If activated, the values evaluated by the “XPath expression” are output when the debug log is active. |
The outgoing connectors of the MessageSelector have different effects:
- OnMessgeSelection outputs the whole selection, so it is operated once
- OnMessage gives the individual message, i.e. it is served as often as there are messages in the selection.
Note: see also Evaluation or filtering of messages in jobs
Hinweis: You can test the expression using Mapping Function GetMessageAsSelectionBase.
Samples:
- Select Messages in message box To.Partner:
//SelectionBase/OutputMessages[@MessageBoxName = 'To.Partner']
- Select Messages without attachments.
//SelectionBase/InputMessages[ count(Attachments) = 0]
- Messages containing 'desadv' in the subject.
//SelectionBase/InputMessages[contains(@Subject,'desadv')]
- Messages with file Name Test.txt
//SelectionBase/OutputMessages[Attachments/@Filename = 'Test.txt']
- Messages with documents of doc type Pricat.
//SelectionBase/InputMessages[Documents/@DocType = 'PRICAT']
- Messages with documents of doc entity type Desadv D96A.
//SelectionBase/InputMessages[Match(Documents/EntityType/@Name, '.*Desadv.*D96A')]
- Messages with entry date .
//SelectionBase/InputMessages[CompareDateTime(@EntryDate, '2007-01-29T17:50:00') > 0]
- Messages with zip attachments.
//SelectionBase/InputMessages[contains(Attachments/@Filename, '.ZIP')]
- Messages of trading partner containing 'Test' equals true.
//SelectionBase/InputMessages[IsTrue(GetTradingPartnerLocationVariable("Test", @PartnerGLN))] - Partner Variables auswerten:
/SelectionBase/InputMessages[GetTradingPartnerVariable('No.EDI', @PartnerGLN) != 'True' ]
Note: The most important distinction is the path / SelectionBase / InputMessages and / SelectionBase / OutputMessages. Messages that are generated within a job with the MessageCreator are selected in the same job with / SelectionBase / OutputMessages and all messages sent to a job with / SelectionBase / InputMessages. All message properties2) that contain the message object can be used within the function. You will get a list of these attributes if you create a new mapping using the map editor and select the eBiss.ClassLib.MessageSelector.Selectionbase3 as the source object.
Cascading of selectors
It is possible to use the messageselectors cascaded. A second selection stage is followed by a further MessageSelector. The messages of the first selection are filtered again by a second selection.
Important: The cascaded MessageSelector (second selection stage) now has the / SelectionBase / SelectedMessages available as MessageListen selection.
