When you’re creating a relationship between two people, Mosaic enforces age restrictions in place if it's a parent-child relationship. This is based on the data in the relationship_type_group column. If the information is not right, you'll see the error message 'The subject must not be younger than the relation'.
If this error message pops up, here's what you do, depending on whether we're hosting your database or you are:

You’ll need to find the relationship type that isn’t working within the table mo_relationship_types. Check the information within the column called relationship_type_group.
For example, if the relationship is mother:Child then the relationship_type_group should be Parent:Child. If this is incorrect, then you’ll have to correct the data.
To fix the relationship type issue, here’s what you’ve got to do:
Identify the Incorrect Relationship Type: You’ll need to query the mo_relationship_types table to find the relationship type that’s not working correctly.
Check the relationship_type_group Column: Have a look at the info in the relationship_type_group column for the identified relationship type.
Correct the data if necessary: Make sure the relationship_type_group column contains the correct value. For example, if the relationship is mother-child, the relationship_type_group should be Parent:Child.
Example of code used for the change:
UPDATE mo_relationship_types
SET relationship_type_group = 'CHILD:PARENT'
WHERE relationship_type_id IN (xxxxx ) –Enter the IDs that need updating
