Calling a R/3 transaction from a non SAP-System

Hi everyone,

i have a problem in which i dont know how to move on because i cant find any good information on how to solve this issue.

The problem is that we have a Non SAP-System which is Delphi. Now we want to do develop a button in this system in which we can open a SAP Transaction in an R/3 System. We do have a remote connection call but we dont know how we could create a R/3 Session with a transaction code and also pass parameters to this.

Does anyone have an idea on how to do something like this?

I hope someone can help on this issue.

Thanks alot

Rene
