# Analysis Source Types

An **Analysis Source Type** describes the features applied when importing an analysis source, such as the effective date
range, transaction ID selection, etc., as well as relevant MindBridge column definitions. These features determine which
steps occur during the analysis source import process.

### Alternative MindBridge field names for non-MAC account groupings

When using a non-MAC based account grouping, some MindBridge fields use a different name (for example, `mac_code`
becomes `custom_code`). This is identified by the `mindbridgeFieldNameForNonMacGroupings` field, which describes which
MindBridge field name to use instead.

Additionally, when using a non-MAC based account grouping, some fields may become required. This is indicated by
the `requiredForNonMacGroupings` field, which is set for all fields that specify
a `mindbridgeFieldNameForNonMacGroupings` value.
