Contact Lookup Mapping to Custom Module CRM via DataPrep

Contact Lookup Mapping to Custom Module CRM via DataPrep

Hi DataPrep Team,

I'm facing an issue with Contact module lookup mapping to a custom module during the DataPrep-to-CRM migration.

As per the documentation, the mapping format for lookup fields should be:

<Lookup_Field_API_Name>.<Lookup_Module_API_Name>

For example:

Account lookup: Account_Name.Account_Name

Custom module lookup: Item_Name.Name

However, this format does not seem to work when the lookup field is mapped to the Contact module.

When we use a Contact lookup field in a custom module, the display value is a combination of the Contact's First Name and Last Name (i.e., the Contact Name). However, the Contact module does not have a single Contact Name or Name field; instead, it has separate First_Name and Last_Name fields.

I have tried different combinations using these field/API names, but none of them seem to work.

Could you please check and confirm the correct way to map a Contact lookup field in a custom module during DataPrep migration? Specifically, which API name/value should be used for the Contact lookup?

It would also be helpful if you could confirm whether this is a limitation or expected behavior of the current system.
