Send data to ASSIST4

To send data to the ASSIST4 system you need a engine which actually makes the request. To create the engine you can pass the ID of the system you want to send data to, to the factory class /AEB/CL_CT_PB_AS4DOC_XXX_FA. Then call the method SET_CUS_DATA and pass it the business facade name and the data.
The business facade name is made up of the literal 'As4Doc' and the external Name of the document (found in the definition) in the ASSIST4 system separated by underscore.
