Identify required fields for an MB01 transaction in SAP

As you have mentioned that you have access to SAP system. The solution lies within. Specify the transaction SE37 and mention the BAPI call that you have identified. It will navigate you to proper documentation of the call.

But in order for that documentation to be of any help, you will still require movement type for your system. You can check it out with your infrastructure team to help you identify the movement type. Once you know the movement type, you will require other details like material number and others for more details. But that can be determined with minimal efforts.
