The fields visible on the relationship side panel for the source object are:

Property	Description
Source Object	The name of the Object that represents the 'source' part of the relationship at object level.
Column Name	The name of the Column for which the mapping will be created.
SQL Source Expression	SQL expression for this column is used to extend source queries. Generally used for source type casting and case statements. Example, CONVERT(VARCHAR(27), @@this, 121).
SQL Target Expression	The SQL expression used to extend target queries. Generally used for source type casting and case statements. Example, CONVERT(VARCHAR(27), @@this, 121).
Dataflow Expression	The expression used to calculate the value of the derived column via ADF. ADF expression syntax is used.
Solve Order	Used for Expressions that need to be parsed in a specific order. An example of use would be if you want to split a very complex calculation up into multiple expressions that are derived in a specific sequence.

They map to the target object, which can have the following properties as part of this relationship:

Property	Description
Target Object	The name of the Object that represents the 'target' part of the relationship at object level. This will be the Target Object visible in the Column Editor.
Column Name	The name of the Column against which the mapping will be created. This will be the Target Column visible in the Column Editor.
SQL Source Expression	SQL expression for this column is used to extend source queries. Generally used for source type casting and case statements. Example, CONVERT(VARCHAR(27), @@this, 121).
SQL Target Expression	The SQL expression used to extend target queries. Generally used for source type casting and case statements. Example, CONVERT(VARCHAR(27), @@this, 121).
