Hello Dave,
I have tested the configuration again and the configuration is same as said above
I used the simulation via transaction /SAPSLL/SIM_IMP_EXT and debugged the program and found that, the system is validating the document type for preliminary documents under the program /SAPSLL/SAPLAPI_6800_CSD with form CUHDA_DETERMINE in line 889 and 890
Could you please help me why system is determining the preliminary document?
I have configured the scenario from USA (Export) to Germany (Import).
