Issue:
Potential model corruption in 2E Version 8.6 (1547) Iseries
Environment:
IBM Iseries  AS400
Cause:
1) We had 2 MASTER fields (with conditions) 
'MASTER - UNIQUE NBR KEY' (referenced by most of our major file keys) 
'MASTER - UNIQUE NUMBER' (looks like used by 50 functions) 
with their equivalent conditions. 
The programmer somehow in attempting to create a new field 'HLSI Address Unique Numbr' renamed 'MASTER - UNIQUE NUMBER'. 
Then he referred the new field to 'MASTER - UNIQUE NBR KEY'. 
Looks like the conditions for 'MASTER - UNIQUE NBR KEY' have been replaced by 'MASTER - UNIQUE NUMBER'. 


Is there a way we could recover the conditions 'MASTER - UNIQUE NBR KEY'  
Resolution:
recover model from backup or Re-reference the fields which had been corrupted So go through the model and re-referenced fields (using 2E) back to the correct master field.
