    Hi everbody,

     

    got the solution. First problem was to choose the wrong "offerID"-column to get a relationship.

    I created a unique ID in the Pricelist concatenate with OfferID + Month(ValidFromDate) + Year(ValidFromDate).

     

    Thanks for replies and help.

HI EMGI,

 

You can try to create calculated table with 'Union' and 'DISTINCT' functions to merge columns and get unique id.

Sample formula:

Link Table =
DISTINCT (
    UNION ( VALUES ( calculated[OFFER ID] ), VALUES ( Pricelist[OFFER ID] ) )
)

Anonymousthank you for reply.

I created the linked table according to your explanation above.

I create a table with OfferName of the calculated table and the List Price of Pricelist. If i choose "don't summarize" i get the error message "can't display the visual".

What do i have to do to create a visual with the correct list price for each OfferName( Product) ?

 

Hope you can help me, Anonymous

    Hi EMGI,

     

    Have you drag the product id(from link table) to table visual? Current power bi seems not support to analysis mapping with multi-columns, you need to drag summary column to help power bi correct recognize records mapping.
