HI,
I would use the SpatialRelator to determine spatial relationship (collect 2010 polygons contained by each 2014 polygon), then use the ListSorter and ListIndexcer to select the largest polygon.

It's a simpler solution.
Dear Takashi
Thanks for efforts and sharing the above info , I apply the second answer is not working with me as I want especially if there is many polygons 2010 inside or intersect with 2014 , I want the MAX polygon area (Fill area within 2014 boundary ) to be select only and escape the other polygon ...
the blow pic show the result from the second sol , the system must select (3) because MAX area fill inside the boundary or 2014 , but in the blow pic it shows that system select ""4""
If you need to select a polygon whose overlapping area is largest, the Clipper might be helpful.
Dear Takashi
WOW , amazing it's work fine with me 100% ....
Last question , how I can compare attribute value between two polygon regarding to Building ID if they have same object ID , the idea now the building ID stored inside building 2010 and 2014 I want to compare the building ID attribute value between them if they have same object ID
Thanks , really appreciate your efforts
In the Clipper parameters dialog, set "Prefix Clipper" to the "Accumulation Mode" parameter, and specify a string (e.g. "2014") to the "Prefix" parameter.
Then the "building ID" and "object ID" of Clipper polygon will be merged to related Clippee polygons, as attributes called "2014building ID" and "2014object ID". Note that you will have to change the "Key Attributes" of the DuplicateRemover to "2014_count", since the prefix will be added to every Clipper's attribute name.
Finally you can compare "2014building ID" vs. "building ID", "2014object ID" vs. "object ID" for each resulting polygon.
Dear Takashi
Thanks for your feedback , actually I will give you clear picture what I am looking for , as know by using the previous methodology I got the result MAX area polygon selected it's okay , now the second stage is to compare automatically between the MAX area result (Lets name it R) and the building 2014 if both of them have same ID (object ID/ KEY) I want to confirm as QC work if the building 2014 have same BIN as the MAX result area (R)...
If both have same BIN it will pass otherwise it will give me the list of conflict or building 2014 not have same BIN taken from (MAX Area /R)
see the picture :
If you add prefix "2014" to the Clipper with the way I suggested above, the resulting polygon (2010 building) will have "2014Object ID" and "2014BIN" which have been merged from related 2014 building. The resulting polygon (R) originally has "Object ID" (2010) and "BIN" (2010), so I think you can check whether "Object ID" is equal to "2014Object ID" and "BIN" is equal to "2014BIN" with the Tester transformer.
