They could very easily fix the designer to make this process simple; but instead, we have to put up with this crap. To fix: Click on the association, and go to the mapping details view. Under association, click on Maps to

You need to mapcreatedassociation to the table of the many side in order to finish the process. Click on the association and in the Table Mapping View map the association to the table of the many side - Persons. After doing so you'll need to map the relevant keys on both sides. In a old post I wrote about how to add many to many relationship I showed an example how to do such a thing in Step 3 – Adding Many to Many Association in the Designer. You can look at it here: http://blogs.microsoft.co.il/blogs/gilf/archive/2009/03/07/adding-many-to-many-relationship-between-entities.aspxI hope it will help you.Gil Fink Marked as answer by Yichun_Feng Wednesday, October 21, 2009 1:05 AM Thursday, October 15, 2009 5:34 AM Reply | Quote All replies 1 Sign in to vote Hi,When you create an association in the designer it isn't enough.

Ke1, and Andrew Collins1 1Human Genetics Research Division, Southampton General Hospital, Southampton SO16 6YD, UK; 2The http://genome.cshlp.org/content/11/7/1290.long Sanger Centre, Wellcome Trust Genome Campus, Hinxton, Cambridge CB10 1SA, UK Next Section Abstract The near-completion of the sequence for chromosome 22q revolutionizes map integration. We describe a sequence-based integrated map containing 968 loci including 516 known or predicted gene sequences, 317 STSs not included in these sequences, and 135 nonexpressed multinucleotide is not polymorphisms. The published sequence spans 34.6 Mb, inclusive of gaps estimated to total 1.1 Mb, compared with a top-down estimate of 43 Mb. This discrepancy is discussed, but will not be resolved until more of the genome is analyzed. The radiation hybrid map has 5% error in order and 34% error in location is not mapped exceeding 1 Mb. The utility of a composite location based on evidence other than sequence is limited to regions not yet sequenced. A genetic map conditional on sequence order was constructed from pairwise lods. Its length of 74.8 cM in males and 80.2 cM in females is slightly less than the previous estimate not constrained by sequence order. Five recombination hot spots are detected, with differences in location between the sexes. Male recombination correlates with repetitive DNA, whereas female recombination does not. It remains to be seen whether this is true for other human chromosomes. An algorithm to improve the fit of cytogenetic bands sequence location reduces the discrepancies in cytogenetic assignment from 61 to 38. This sequence-based integrated map is represented in the genetic location database (LDB2000), which is available at http://cedar.genetics.soton.ac.uk/public_html/LDB2000.html. The genetic location database (LDB) presents integrated maps of the human genome, which are now being updated to sequence-based integrated maps (LDB2000,http://cedar.genetics.soton.ac.u
