Application Link Enabling (ALE) is based on the use of Remote Function Calls (RFC) between systems. To define the communication in a system landscape, you must define the RFC calls between the central system and the child systems bidirectionally.
Give the RFC destination the same name as the logical system and enter the name in capital letters.
You have defined the logical systems for ALE distribution.
The system displays the RFC Destination screen.
Group Box/Field | Entry |
---|---|
RFC Destination field |
Logical system name of the child system in capital letters (such as PRDCLNT324) |
Connection Type field |
3 (that is, a connection to another SAP system) |
Description group box |
Short text for RFC connection |
Logon group box |
System user of the child system (such as CUA_PRD_324) and its data. |
You must create the name of the RFC destination in capital letters.
To determine the message server of the child system:
Group Box/Field | Entry |
---|---|
RFC Destination field |
Logical system name of the central system in capital letters (such as ADMCLNT070) |
Connection Type field |
3 (that is, a connection to another SAP system) |
Description group box |
Short text for RFC connection |
Logon group box |
System user of the central system (such as CUA_PRD) and its data. |
This tests only the system user, the password and a basic authorization. It does not check whether all authorizations required for the CUA exist.
