Hi @slyfox 

I would suggest you create a measure to get the correct total.

Measure =
SUMX (
    SUMMARIZE (
        F_Shipment_Delivery,
        F_Shipment[SMP_Id],
        F_Shipment_Delivery[LINK_Delivery_Order]
    ),
    [Distr_NegoCost]
)

Regards,

@slyfox  hi ok so something is wrong, but what are you expecting, can you give me something to compare it to?

Hi @vanessafvg 
Result for this column should be the same as for SM_Negotiated Cost

@slyfox  ok then the problem is your relationships.  you have all your relationships set up to bi directional, you should change that to single and that should resolve your issue

I was having the same problem and your suggestion solved it! THANK YOUUUU! @vanessafvg

I did not find the answer in your posts. Links are set in the form in which it was required.

If you do not know how to solve the problem with the defined conditions, please ignore the post.

@vanessafvg Suggest workflow cannot be applied because it brings to wrong results in row by row calculations.

@vanessafvg 
In my example, only 1/20 of the tables used in the model. My question is simple, within the existing data model it is possible to solve the problem or not?

[vanessafvg]

yes as  i have said, disabling some of the the bidirectional relationships does this, however this is not as simple as you making out,  the onus is on you to understand how power bi works if this does not meet all your requirements.   what i am saying is right now based on your relationship model, this is is what is going to be returned, its important to undertand the behaviour of bi directional relationshipsships. 

[vanessafvg]

@slyfox you mean relationships flow?   then you might need to think about remodeling your data because that is what the relationships set up in both directions do.
