The Default Maximum Length option 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 the Forge Logging system, if so configured.
If you do not explicitly specify a Default Maximum Length, Forge checks against the following limits when determining whether to map a value:
Source properties that are mapped to Guided Search 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 Guided Search property and dimension mappings.

You can override the Default Maximum Length setting on a per-mapping basis by using the Maximum Length field in both the Property Mapping and Dimension Mapping editors.
Example 7. Example
Suppose you use the Default Maximum Length to limit the length of all your source property mappings to be 100 characters. However, you want to allow the P_Description property to have a greater limit (say, 255 characters). You would then use the Property Mapping editor to set an override for the P_Description source property that allows the description to be up to 255 characters:
