About setting a default maximum length for source property values

The Default Maximum Length option, on the Advanced Tab of the Property Mapper, defines the maximum source property value length allowed when creating mappings.

Source properties that have values that exceed this length are not mapped, and a warning is issued by Forge.

If you do not explicitly specify a Default Maximum Length, Forge does the following:

Source properties that are mapped to Endeca properties can have values of any length.
Source properties that are mapped to dimensions must have values that are 255 characters or less.

If you do explicitly specify a Default Maximum Length, that length is applied to both Endeca property and dimension mappings.

You can override the Default Maximum Length on a per mapping basis using the Maximum Length field in both the Property Mapping and Dimension Mapping dialog boxes. For example, you can use the Default Maximum Length to limit the length of all your source properties, but set an override for a Description source property that allows the description to be as long as necessary.
