Error while importing in Agile

Hi ,

We are facing an issue while trying to import in Agile webclient as its showing to map some of the mandatory fields (These mandatory fields are disabled at subclass level and enabled at class level). Please help us on this how can we overcome this issue and import it.

We thought of disabling the attributes at class and subclass level and then import, after import ran we can re-enable fields at class level ( As initially setup) But if we do this we will lost all the redline data for which we can't keep track of redline attributes.
