Resolution

* you are probably using a Bdoc type "Generic"

* as stated when creating a Bdoc Generic, it used to exchange data with SAP Application. If that is not the case, simply replace the Bdoc Generic to a standard Bdoc

* A Generic Business Document cannot be linked to an Input or an Output activity. This bdoc has no physical form and hence there are no parser nor builder.
Generic bdoc exists only in memory.

* An intermediate map should be used in order to convert the Generic Bdoc to an InHouse Bdoc (for Output) or an InHouse Bdoc to a Generic Bdoc (for Input)
