I have learned from the support that there is no additional text information at the moment. They will add text information in future releases. But at the moment you need someone who knows this codes. I know the following error codes in scheduling:
Code 32 Server Group Logon not supported (for versions before 1.4.7 + corresponding BIP Addon)
Code 40 Unsupported document extension
Code 47 Mission .NET Libraries on Server
Maybe someone has experience with this code you get.
