    Hi naveen73 ,

     

    Please try these measures.

     

    Current Value - Loans = 
SUM ( 'Table'[Collateral] ) - SUM ( 'Table'[Loans] )
    G = 
VAR G2 = 0.8557287
RETURN
    SUM ( 'Table'[Collateral] ) * G2
        - SUM ( 'Table'[Loans] )

     

    If the problem is still not resolved, please provide detailed error information or the expected result you expect. Let me know immediately, looking forward to your reply.
    Best Regards,

Hi Naveen


I appreciate that this post is already marked as solved but not sure that the solution provided actually mimics the goal seek feature of Excel - if the logic is simple you can reverse it to find the unknown variable (as has been proposed) but in a case like this where you need to iterate through the result of multiple calculations I don't believe this approach works!

 

I've instead proposed an approach using the list.accumulate function in M (excel version https://rsaprahotmail.sharepoint.com/:x:/s/LDIGeneral/EVAB-rjIjAZNjTsKCGO-yT0BmhY7MxFaphB5h-OQBkCAxg?e=Hn6LIN and PBI version https://rsaprahotmail.sharepoint.com/:u:/s/LDIGeneral/EY2hW3C2_INLk0qLjp_jiFsBAxHHITZNixPn3AgI2yDBOw?e=GWnZ2n) - let me know what you think pls!
