We are developing a tool in Java where we will pull the data from various modules in SAP (like Purchase order, Invoice etc). Lets take Purchase Order Module as example. I can get the data using BAPIs (like BAPI_PO_GETDETAIL).
However to implement Authorization, I also want the list of users/groups that have access to Purchase order module. Is this possible? Or can we get the ACL information from the tables in database like EKKO for Purchase order?
I have tried searching for solution but couldn't find any. Please suggest if there is some standard way by which we can pull the ACL information via Java, or if this can be achieved by some custom RFCs.
