Thanks for the suggestions. I have the data structure that needs 2 dimentional Hash of arrays. I will need to find out the Specific ID and their respective Netowrk IDs and which was not used and the used one Network ID to be checked with Last used among the usages. Please check my latest data structure . How i can create a 2 dimentional Hash of arrays and extract the unique data? Can you please consider @array1 as the Key @array 3 is the 2nd and @arra3 is the respective values? Please check ID 500000008

@array1            @array3             @array2    @arra3
