Using SAP connection strings with Liquid UI Server aka GuiXT Server.
A connection string is the string that defines the target SAP ERP system to which Liquid UI Server will connect. The connection can either be via a message server or directly. Connection strings are found in the sapproxy.ini configuration file and look something like the following examples:
- /M/SAPMC1/S/SAPMSPRD/G/GRP_HR
- /H/SAPMSPRD:3600
- /H/SAPMSPRD
The components of the connection string are defined as follows:
- H: Defines the actual SAP system if no message server is used.
- M: Defines the SAP message server if one is present. In this case, the message server would be 'SAPMC1'.
- S: Defines the actual SAP ERP system to be targeted if a message server is deployed. In the example, the SAP system would be 'SAPMSPRD'.
- G: Defines the group that will have access. In our example, the group is 'GRP_HR'.
Connection strings are typically used when there are either multiple Liquid UI servers connecting to a single or multiple SAP ERP systems or when there are multiple SAP ERP systems involved. The following connection string types are supported:
| Connection String | Description |
|---|---|
| /H/server_name | This format is used for a single SAP application server. If a single Liquid UI Server is deployed, this format also can be used for that case as well. |
| /H/server_name/G/group_name | This format is used with a single application server when user groups must be specified. |
| server_name:port_number | This format is used when a single application server and the connection port both must be specified. |
| /H/server_name/S/server_name | This format is used when there is an application server (or a Liquid UI server) connecting to multiple application servers. |
| /M/server_name/S/server_name/G/group_name | This format is used when a SAP message server is connecting to multiple SAP application servers and the user's group must be defined. |
