Hi @Kumar_27 ,
Example,
Type 1N: when you try to link recipient schema with broadLogRcp schema using enrichment, you have to select this 1N option as 1 recipient may have many broadlog records
Type 11: Consider you have 2 schema - Student and Contact Info, where one student will definitely have one contact info. Then to link this schema in enrichment you can use this type 1:1
Type 11 may have a non-existent target: With the same above example, if you feel 1 student may have 1 contact info and also some students may not have contact info. In that case you can use this type (1 to 0/1 )
