direct discovery

[pkpandey]

I have a dimension BUYER_K, and measure Totalkgs_DD in direct discovery and it is joined with the in memory key BUYER_K. While calculating the BUYER_K wise Totalkgs_DD, it is showing correct value but while calculating value SALE_NO_DD wise, it is showing wrong value. What might be the problem. My direct discovery script and data model screen shots are as follows.

directdiscovery:

  "Sale No" As SALE_NO_DD,

  Buyer As BUYER_K,

  Season As SEASON_DD

measure

  Totalkgs As Totalkgs_DD,

  Totalkgs*AuctionPrice As VALUE_DD

from eAUCTION.dbo."OTB_12_13";

Please help, this is very urgent.
