How to create a lookup on Dimension(SysDimesion) ENUM

How to create a lookup on Dimension(SysDimesion) ENUM

Note:
1. DimentionSetCombination is table in Whitch dimesion hierarchy stored 
2. MachineHour is a customized table in this example, you can use your own logic in the same
3. fieldId2Ext is a X++ key word which is used to access a particular array index value.
 example:  fieldId2Ext(fieldNum(DimensionSetCombination,Dimension),4)


public void lookup()
{
    SysTableLookup       sysTableLookup =      SysTableLookup::newParameters(tablenum(DimensionSetCombination), this);
    Query                query;
    QueryBuildDataSource queryBuildDataSource;
    QueryBuildRange      queryBuildRange, queryBuildRangeDlvryWH;
    ;

    sysTableLookup.addLookupfield(fieldId2Ext(fieldNum(DimensionSetCombination,Dimension),4), true);

    query                   =   new Query();
    queryBuildDataSource    =   query.addDataSource(tablenum(DimensionSetCombination));
    queryBuildRange         =   queryBuildDataSource.addRange(fieldId2Ext(fieldnum(DimensionSetCombination,Dimension),3));

    queryBuildRange.value(MachineHours.CostElement);
    sysTableLookup.parmQuery(query);
    sysTableLookup.performFormLookup();
}
