Thank you Sudhir.
But how the guy responsible for authorize the requests know that some customization can affect other system?
Suppose the HR is already in production and working fine. Then I will implement Logistics and make a change in a customization object that the HR also use. So it will be a problem, because HR would not be working correctly.
Dear Leandro ,
Yes you can use ALE . Actually we have basically the communications through two methods
1. ALE - for communications between two sap systems
2. EDI - for communications between two ( sap or SAP & non sap system )
So in our case you have to do the RFC configuration using the t code SM59. For this you can take the help of the BASIS person.
Please follow the below link will be helpful for you.
