What characteristic must two fields share when mapping them in Lead Conversion Mapping?

In the context of Lead Conversion Mapping in NetSuite, the characteristic that two fields must share is the same type. This is crucial because mapping involves transferring data from one field to another, and for this transfer to be successful, the fields need to have compatible data types. For example, if one field is set up to contain numeric data, the corresponding field for mapping must also be designed to handle numeric data. If the data types are mismatched, it could lead to errors or data loss during the conversion process.

Maintaining the same field type ensures that the integrity of the data is preserved and that conversion operates smoothly, allowing users to seamlessly transition leads into customers without encountering type-related issues. This focus on data consistency is essential for maintaining accuracy within the CRM system.
