BPC allocation Script logic

Hi All,

I am working on allocation Logic and i am using it the first time , requirement is i the COGS has to be allocated to the Profit centers based on the individual sales figure ratio in comparison to the Total sales figure for the Profit center Node.

ie sales value of the individual Profit center  /  sales value of the TotalProfit center * Total COGS value entered by the User for the Total Profit center.

Thanks in advance
