Technical Requirements
External Systems
External systems must support TCP/IP.
The RFCSDK for the respective platforms contains the following libraries and includes:
|
This include file contains all data types and structures required and the prototypes (declarations) of the RFC calls. | |
|
This include file contains all the RFC calls required to manipulate internal tables | |
|
Depending on the platform, the following libraries are required: | |
|
OS/2: |
librfc.dll and librfc.lib for Compile/Link | |
|
Windows 3.1/3.11: |
librfc16.dll, librfc2.dll , librfc3.dll, librfc4.dll | |
|
and librfc5.dll and librfc16.lib for Compile/Link | ||
|
Windows NT/95: |
librfc32.dll and librfc32.lib for Compile/Link | |
|
UNIX-Platforms: |
librfc.a | |
SAP R/3 Systems
For RFC between external systems and R/3, there are no specific requirements in the R/3 System, except that the R/3 System has to be at least Release 2.1.
Contrary to this, RFC between SAP R/2 in an IBM environment and SAP R/3 or external systems requires an SAP gateway to run on a machine that supports the SNA LU6.2 protocol for the IBM host. The SNA product must also be installed on this machine, and the SAP gateway must be operable with this product. This is necessary, because some SNA products are not compatible on the same machines.
The following SNA products are currently supported:
SAP R/2 Systems
Communication via Remote Function Call (RFC)
SAP Intersystem Communication
Host communication with DOS, OS/2
Host communication with other LU6.2 systems
Communication via Remote Function Call (RFC)
SAP Intersystem Communication
Host communication via TCP/IP (BS2000)
