Limit SR Classification based on other attributes

1. Copy classfication diaglog from Library.xml and paste it into presentation (sr.xml) file.

<dialog id="associateClassification" label="Classify">
        <tree beanclass="psdi.webclient.beans.assetcat.AssociateSpecBean" allowqualifiedrestriction="true" height="250" id="associateClassification_tree" maxchildren="1000" relationship="CLASSSTRUCTURESR"  openfirstlevel="false" width="600">
            <treenode displaykeyattribute="false" displayobjectname="false" id="associateClassification_tree_node1" keyattribute="classstructureuid" objectname="CLASSSTRUCTURE">
                <treeattribute dataattribute="classificationid" display="true" id="associateClassification_tree_node1_attr1"/>
                <treeattribute dataattribute="classificationdesc" display="true" id="associateClassification_tree_node1_attr2"/>
            </treenode>
        </tree>
        <buttongroup id="associateClassification_2">
            <pushbutton default="true" id="associateClassification_2_2" label="Cancel" mxevent="dialogcancel"/>
        </buttongroup>
</dialog>

2. create a new relation in SR Object for Classstructure as child object

commoditygroup=:commoditygroup and contract=:contract

3. import sr.xml again and good to go.

Thanks to Haris who did it atlast.
