This documentation is not using the current rendering mechanism and will be deleted by December 31st, 2020. The extension maintainer should switch to the new system. Details on how to use the rendering mechanism can be found here.
Some field names are too long¶
Oracle for example has a restriction on table and field names, they can only be 30 bytes long. Some fields, especially of extensions adding fields to existing tables may violate that restriction. A way to work around this is to configure a field name mapping for those long names onto a shorter one before creating them (through the Extension Manager or Install Tool).
