Which TN bizdoctype need to be configured RN PIPs


Any documentation available to find which TN bizdoctype I need to use for configuring the PIPs because I could not find proper information in the RN Specifications also.

For example 4A5 has 2 TN bizdoctype, which one I need to use if I do Inbound Mapping.

Similarly for 3A4 u have 4 TN bizdoctype, which one to use???

Is there in any documentation clearly explains which TN Bizdoctype needs to be used exactly for Outbound Mapping and Inbound Mapping.

I require for 3A4, 4A4, 4A5, 4C1, 4B2 and 4B3
