Hi All,
I want to use Cluster Join in MFD. Can anyone let me know how to do this as I have seen several options but can't.

Msam,
There are a lot of documents on the IB website that tell you all the ins and outs of creating cluster joins.
Basically, what it does is defining more than one dbms table in your master and access file.
So, you start with naming the structure (FILENAME=), follow this with each and every segment (table) description that you need.
Then do the same in your access file, specifying for each segment (table) where it is located and how the join is to be performed using the ixfld and keyfld keywords.

We tried using Cluster Joins to 'build in' the joins to look-up in x-ref tables values decoded columns in a table that were encoded. The objective was to have the synonym make the 'plain text' meanings available to the user. [The user could see, filter on, and test for the code's meaning, not it's numeric value without having to know of the decode table(s) or how to JOIN to them.] Our table had lots of such coded fields, and the technique worked OK until we got to decoding about 27, or so, at which point we reached the limit WF allows. We had to abandon the technique at that point because we couldn't offer the user a table with less than all the coded columns decoded.

Look up Cluster Join in the Help section of Dev Studio. Basically just right click on Masters, select 'New' -'Synonym Via Synonym Editor' give it a unique name and then Right Click to bring in other Synonyms for Joining.
