How to find the required tables of a BAPI function?

I'm new to SAP and studying calling some predefined BAPI function using JAVA. I have a question. I open the function BAPI_QUOTATION_CREATEFROMDATA2 in SE37. In it, I found import and tables. The import is the parameters I need when calling this function, but in tables, there are about 12 tables and structures, how do I know which is the minimum requirement to call the function? Can anyone help? Thanks.

Solution

Please see the optional column, highlighted in the image below. The tables that are optional are checked. Tables that do not have 'Optional' checked are required. You can see from the image that 'QUOTATION_PARTNERS' is the required table.
