SAP Configuration - Connection Parameters Tab

The Connection Parameters tab is used to specify the SAP system that is to receive the data sent from the Extension for SAP.

Typically, there is more than one SAP system with which the Extension for SAP will be interacting. For instance, there is usually a test system, development system, and production system. Therefore, when the Extension for SAP is sending status messages or EDI documents to SAP, it needs to know exactly which SAP system is to receive this data. To provide this information to the Extension for SAP, you must specify values for the group of boxes listed on the Connection Parameters tab. The group of values as a whole identifies a specific SAP system. Each group of values is written as a database entry using the Connection Name as the identifier.

The settings on this tab are used when you execute the Extension for SAP program SAPINT.EXE with a function that sends status or EDI data to SAP. You indicate the target SAP system by passing the connection name, (that is, the identifier for that set of configuration parameters that you specified in the Connection Name box) as a parameter for the SAPINT.EXE program. The Extension for SAP program then invokes a program provided by SAP called STARTRFC or ALECLIENT and fills in its parameters with the specified group of values from the Connection Parameters tab. The STARTRFC (or ALECLIENT) program accomplishes the actual transfer of data.

This is the Connection Parameters tab on the SAP Configuration dialog box.

This table describes the parts of the Connection Parameters tab and their functions, and provides examples where applicable.
