I have linked a Product Master Table written in IBM/Universe using Universe/ODBC. I am able to perform lots of queries and forms in MS ACCESS . The linked table has a field called UM (Units of Measure) and the UM field has mutivalue fields stored as shown below.

EA    16
 
The first and second lines are not consistently in the same order, because of selling practice. MS Access when queried for the field containing multivalue looks only for the first line. However in the native Universe database, retrieve (aka query) shows the results like this
PMID    UM    F64
40021    CS    1    
            EA    16
As you observe PMID does not get repeated for EA.
 
I am looking to see the query results like this
PMID    UM    F64
40021    CS    1
40021    EA    16
40023    EA    9    
40023    CS    1
 
Any help is very much appreciated.

The treatment of multi-valued column types is defined by the database driver. Maybe there is an option setting that will result in common data being repeated over all values.  In doing some research about your question I found indications that the driver puts CR+LF between values, which will have all sorts of odd behaviors in Access.

You have shown an example of "the native Universe database, retrieve (aka query) shows the results like this". What does a query result look like in Access? Is it possible that CR+LF characters appear between values in a multi-value column? If that is the case then there is a pretty straightforward solution.

Here is what appears to be an excellent resource for understanding how IBM Universe works with an ADO.NET driver. It is intended for .NET programmers but the concepts are universal to all driver-based access to the data.

"7) Last, but not least, multivalues.  As described in my previous article there are a few different ways to configure your dictionary to return multivalues, but the method that IBM recommends is to list the multivalued fields in a special "association" dictionary entry."
