we use Dimension Builder to create OLAP dimension info on the master file after we generate the synonym. But, occasionally, we have to modify the table and re-gen the synonym, in which case the OLAP dimension info is gone. We wonder if there is a way to preserve the OLAP dimension info so that we don't have to re-do the whole thing again. Thanks.

You can put the OLAP stuff in a focexec and -INCLUDE it. Look up OLAP Dimensison Tool. Here is a link:

That way you don't have to keep changing the master.

thanks, Ginny. We did not choose the fex approach under the assumption that:
1. creating the dimensions on a fex level will have a performance overhead to running the report;
2. will need to create JOINs on the fex whereas implementing dimensions on the master file will not need to create JOINs on the fex and hence, minimize performance overhead.

Are we incorrect in the above assumptions? If we are correct; then, we would still be interested in exploring ways to preserve the dimension info on the master file level.

thanks.

I would think that the performance hit, and it would only be in parsing not executing, would be minimal. I would rather do that than have the administrative nightmare you are currently dealing with. At our shop, we don't allow manual modification of relational masters for just such a reason. At any rate, why don't you try one and check the performance to see if it really will be a problem.

thanks Ginny!
