Circular dependency Error

Hi Power BI people, we have a situation where we are getting a circular dependency error. The issue is we are doing some forecasting of closing stock based on the numbers of previous year but the current numbers are also based on historical data and when we try to do the calculation using variables we still ae unable to get the right number.

I am attaching an excel + PBI file for the calculations. The excel file is for the validation and in the Power BI I have given the context of each calculation. Once you open it, you will understand what we are trying to achieve.
