3332447 - Output missing in STO - SAP S/4HANA Cloud

You have configured output determination for purchase orders in the APP 'Output parameter Determination'
and it works well, however when you create a 'Stock Transport Order' no print or email output is determined.  

SAP S/4HANA Cloud

Create a Stock Transport Order in the 'Create Purchase Orders - advanced' APP and check the messages.  

Missing configuration

In general no output would be expected in the Intra Company STO scenario because there is no vendor involved. 
However if you want to issue a print or email output for an STO it can only be done for a document type that has the 'Transfer Vendor' flag set against the document type. 

In the public cloud only STO type 'UD' is delivered with this flag set and the field is not editable. So you can generate PO output for the 'UD' document type or you can copy 'UD' into your own custom STO type. You copy the document type in this customising - 'Define Document Types for Purchase Orders' (SSCUI 102909).

*Note there are no partners in an STO, the system will take the supplier data, email address etc, from the supplier assigned to the supplying plant. The configuration in OPD for an STO is the same as a regular PO except for the required 'Transfer Vendor' flag against the PO type.
