Field mapping

[Aniket Shukla]

how to overcome the error "An existing map to this target field already exists", but i am mapping to two different fields like:

• purchase_order_line

• purchase_order_line.short_description

Other field is mapped to purchase order line and first one is mapped to purchase order line short description.

Hi,
The error is occurring because the same target field is being used in two mappings. While the target field is the same, only the reference value field name differs.

The reference value field name is used for target reference fields to indicate which field from the source should be matched, for example, the 'name' field in your reference field's table.

To resolve the issue, ensure that only one mapping is created for this target field.
