When trying to save a configured Import Package, the following warning is displayed and the package configuration is not saved: The XML is too long to store in the database. Remove some document type or keyword type mappings and try again.
This issue occurs because the package configuration is saved as an XML file in the database. The size limit of the XML file is 64,000 characters. If your package exceeds this limit the warning is displayed and you cannot save the package configuration.
To avoid this issue, create several smaller packages that contain different Document Types instead of configuring a single package to contain all the Document Types requested.
