Validation is performed at the time of configuration and also at runtime when the external table is accessed. The characters allowed is a short, restrictive list; however, if a need arises where other characters are required, there are 2 settings that can be added:
<add key="AllowAdditionalDBCharacters" value="" />
<add key="DBNameSuppressFromEscapingCharacters" value="" />
These settings must be placed in the <appsettings> section of both the OnBase Studio obstudio.exe.config file and Application Server web.config file. The first setting is the only required setting to whitelist a character. The second setting will remove the quotes around the key.
