To register a new Containerizer, select the Containerizer entry in the respective repository and select Create from the context or main menu. If the type exists multiple times in the repository under different subtypes, you can use the MapFrameVariable DocumentSubType to specify the type to use, e.g.:

Note: The subtype should be determined by function for outgoing docs for which there are multiple subtypes in the repository. SetTargetFrameVariable('DocumentSubType', 'SubType')¹⁾ Otherwise warnings will be displayed in the tracelog at the containerizer and it may happen that the outgoing message is created with the wrong subtype.
