# How to assign Leads to two different queues available in the ratio of 60% and 40% (Round robin)

I am having two queues "GOLD" and "Platinum" which are having separate group of users.
Now I wanted to assign 40% of the total leads to GOLD queue and rest 60% of the total to PLATINUM queue which all are coming from web-to-lead.

For eg. Suppose if we are getting 10 leads at a time then assign 4 to GOLD queue and 6 to PLATINUM queue.

Can someone help me here?

Starting from the topic How do I create a round-robin assignment for Leads or Cases to users?, the basic idea has to be extended to support your desired ratio.

The easiest way to do this is to alter the Round_Robin_ID__c formula field suggested in the help document:

``````IF(MOD(VALUE(Lead_Number__c), 10) < 4, 0, 1)
``````

Here, we'll return 0 if the number ends in 0, 1, 2, or 3 (4 of 10 digits), otherwise return 1 if the number ends in 4, 5, 6, 7, 8, or 9 (6 of 10 digits). You can extend this logic out as far as you need to; if you wanted to change it to 45/55, you could use 100 as the base divisor, and check for less than 45 instead.

If you'd rather assign leads more pseudo-randomly, you could mix it up with CASE:

``````CASE(MOD(VALUE(Lead_Number__c), 10), 0, 0, 3, 0, 6, 0, 8, 0, 1)
``````

Where numbers ending in 0, 3, 6, or 8 comprise the 40%, and numbers ending in 1, 2, 4, 5, 7, and 9 comprise the 60% (or any other way you'd like to split it up).
