Sometimes we need to clone MDA objects - to create similar objects with minor changes.

Ex: Weekly and Monthly data capture objects - same structure and same metrics at a different granularity.

If we export fields with headers and try to create fields with that list - we are running incorrect datatype issue. If a field has null values, datatype can’t be determined. If a field has only 0s and 1s it’d shown as a boolean. Similarly URL fields can be shown as strings and percentage fields as numbers. 

Hence, it’s better to have a clone object facility.
