We would like to use the Amazon Business functionality. Can you please help me with some document on SRM integration with Amazon or Amazon punchout with SAP SRM.
We would like to understand the integration process or architecture.
For Amazon punchout catalog, it belongs to external catalog.
Please refer to my answer in the following thread:
First, you have to upload the material data from MM side to MDM data manager.
Then to synchronize the data, it would be better to replicate material master from MM to SRM as well.
At last, you may refer to KBA 2475664 to get known about how to enable the catalog option in MM side so that you could purchase catalog items in MM PO/PR.
