//Info: JSTN-1127
In mapper 2.0 version, we can easily build complex JSON structures that include nested arrays and make use of data type validation for required fields and incompatible data types.


//Note:
- When you click Save and have mapping configurations in both Mapper 1.0 and Mapper 2.0, all mappings configured in either version are saved. When the flow is run, however, it will only use the mappings configured in Mapper 2.0.
- To use any mappings you create using Mapper 1.0, you must:
- Delete all mappings from the Mapper 2.0 interface.
- Verify that the record or row structure is set to Create destination record {} from source record {}/[].
- Remove all blank lines from Mapper 2.0.
