    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.

Ah sorry,

I thought you already had the relationship.

 

Then you have to create a 'link table'. What you probably need in this link table:

- OrderId

- PartnerId

- Startdate

 

All defined as primary key. Then link to your other tables. Then your many-to-many relationship becomes one-to-many and one-to-many

    My problem is how to create a link table with the values of the other two tables?

     

    Which columns i need in the link table to get going on with the calculation?

     

    I think the table has to be dynamically updated every time a new OfferID and a new price is inserted, or am i wrong?

      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] ) )
)

       

      Regards,

        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
