CK11N problem

Dear All Experts,

When I use ck11n to run the standard cost for a material, the result is not right.

The result is 55.83 per L, and it use the info record is 5300014286.

And I check the price of the info record is 53.68 per L, pls refer to below:

Could you tell me what's the reason for this?

Thanks!
