RE: web services does not show workflow companies
Most likely you're on GP 18.2/18.3/18.4 and the install/upgrade of Web Services wasn't done with the required media being used, as mentioned in this blog:
community.dynamics.com/.../microsoft-dynamics-gp-upgrade---upgrading-microsoft-dynamics-web-services
If the correct media isn't being used, you'll run into issues mentioned in the blog and what you're seeing: "you'll see issues like a blue question mark next to the Functional Currency check, then if you go past that, no companies will be available for selection, and you won't be able to continue the install/upgrade."
--If you're on GP 18.2, you must slipstream the KB 4527536 MSP patch for Web Services into the GP DVD being used to install/upgrade Web Services.
--If you're on GP 18.3, you must be using the MDGPFALL2020 DVD which already has the required KB4527536 MSP patch built into it.
--If you're on GP 18.4, you must be using the MDGPFALL2021 or newer DVD which has a newer MSP file in it that is required.
These changes were made to Web Services to allow it to work in a environment with TLS 1.0/1.1 disabled, using an AD security store and some other changes around that.
Let us know if you have any questions.
