Firm Profit exemption

Hi pl. clarify.... Ours is Pvt Ltd company and claimed Profit received from Partnership Firm Rs.2 lacs at the time of filing of Return as per their Allocation.  But after completed their assessment Firm Profit ascertained by the assessing authority Rs.5 lacs of our share.  Our pvt ltd company assessment also completed.  

So how can i get the Rs.3 lacs of our profit share in the pvt ltd company and in which year i can be get claim and relief?---
