I tried to creating a new field called 'new_sourcecampaign' in Contact but got the following error when attemting to map it with campaignid..
Invalid field map
This field map is invalid. A valid field map must meet these requirements:
- The data type must match. - The length of the target field cannot be shorter than the source field. - The format should match. - The target field must not be used in another mapping. - The source field must be visible on the entity form. - The target field must be a field a user can enter data into. - Address ID values cannot be mapped.
