Choose company list empty in SAP Business One



When I create Business One test environments, it happens to me quite often that I have difficulties to connect to the SLD server.

The symptoms is that when I start Business One, the “choose company list” is empty.


I created this cheat-sheet of what to check:

  • Check that the SLD service is actually service – it’s pretty obvious, but let’s start with the basics!
  • If the Internet Proxy is set, try to remove it
  • Check whether the SQL server is using a static port – it’s easier to manage with static ports
  • Firewall or another application is blocking one of the following ports (30000, 30001, 30010, SQL Server Port)


Hope this helps anyone around!

Don’t hesitate to comment below if you do any other checks.

      Thanks for the tips and trick.

      Another option to rectify the above error which i have faced is to check whether SQL Native client is installed in the respective system where SAP B1 is installed. Once  SQL Native Client is installed the above problem would be solved.
