If I alias one of the fields, it works fine, but then I don't get the replica data sets I was after.I know I can put a filter on the read from QVD, but then I lose out on the advantage of optimized reads.
Re: Is this a bug? Loading same fields with resident
The NOCONCATENATE advice above is correct, but be careful that you dont leave these tables as-is as identical columns in multiple tables will cause a synthetic key to be created. If you data model has lots of identical columns then the size of synthetic key could be considerable and take a long time to calculate.
If you want the tables in your model then look at QUALIFY as a method of ensuring the columns remain unique to the table. (hint: use UNQUALIFY for the fields you do want to join on)
