Hi ,
When we tried to import managed solution from Dev environment to Higher environment we are getting "An error has occurred. {1}{0}" error. When we checked while exporting the solution there was a dependency, but the catch here is 
When we checked in dependency, we are getting this dependecy error for mms_requestidname field which is not available but name field crated internally by system for Look up. we are not able to move solution due to this. Please let me know if any body have faced this issue before and if any resolution.
Regards,
Tejas
