  2. Organizations using a proxy server can click the Gear icon in the bottom left hand corner to configure the Gateway to work with an organization’s proxy.

Setting Up SQL Server Connection

In this section we will detail how to create a connection to a source SQL database. A source SQL database can be the ERP database or a staging database. As previously mentioned, generic views are available within the Gateway app for supported ERPS.

In order to create a connection, the Gateway server must be able to communicate with your SQL server.

  1. To begin, click Add to start configuring a connection to a SQL database. 
  2. Users will be prompted for SQL Server information including
    • Connection name: a name which will appear within the Solver Cloud application. It is recommended that this name be informative for troubleshooting purposes (such as “machine name – gateway”
    • Authentication Type: This is the means by which the app will connect to the database (defined later on). Choose between windows or SQL auth. In either case, the user name provided must have read permissions to the Source database.
      • Complete the Username and Password text boxes below based off the authentication method selected.
    • Server Address: type in the SQL server address. This can be the server IP address or the host name.
    • Database: type in the name of the database where the source data is located.
    • Port: by default, the gateway uses port 1433. If your SQL server is using a different port, click Change to type in the SQL server port
    • Timeout: by default the Gateway has a two (2) hour timeout. If you need to increase it, click Change to increase the value.
      • Values typed in, must be in seconds
  3. Upon completing this info, the Connect option will become available. Click Connect to establish connection. If the information provided is correct, a connection will be established and users will be directed back to the Gateway homepage where listing of the available source data will appear.

You have successfully created a connection. At this point, return back to the Solver Cloud application to begin configuring an integration.

Setting up the File Import Connector

  1. Click the add option within the File Import – Excel and CSV connector.
    • Name your connection: this will be the name of the connection that you choose from within Solver Cloud. It is best to make this name informative to include information such as the computer name where the gateway is installed.
    • Find Folder Path: Fill this information out by either typing in the name of a local drive or using the “Find Fold Path” to locate the folder containing files to be imported.
      • The folder path feature only supports local computer drives, it does not support network locations
      • When navigating through the local drives, double-click to expand the drives.
    • Indicate whether or not the file has column headers. Fill out the information request.
  2. Click Connect.
    • Depending on the number of files, it may take some time to load. Each excel file is opened to populate sheet names within the application, it is best to reference a folder that contains on the files that will be imported for performance purposes.
