Hi guys,
I would need your help with LOOKUPVALUE function. I have pretty complex model so I cannot have active relationships between tables DIM_Products and DIM_Locations.
This is how the tables look:
DIM_Products
- Product ID
- Location ID
DIM_Locations
- Location ID
- Location Name
I need to populate Location Name into DIM_Products table. I tried to duplicate table and create new DIM_Location to Product and create relationships - then both RELATED and LOOKUPVALUE functions worked well.
LOOKUPVALUE('DIM_Locations to Products'[Location Name], 'DIM_Locations to Products'[Location_Id], DIM_Products[Location_Id])
RELATED('DIM_Locations to Products'[Location Name])
Due to size of model, I cannot accept to create such dummy tables, and therefore I removed duplicated table and remove relationship (respectively to keep inactive relationship) and rewrite the function as:
LOOKUPVALUE('DIM_Locations'[Location Name], 'DIM_Locations'[Location_Id], DIM_Products[Location_Id])
However this function is retrieving blanks values. As far as I know, LOOKUPVALUE does not require to have relationship between tables - any ideas what can be the root cause here?
Thank you

Solved! Go to Solution.
Thanks a lot! The I change type to number and then back to text and suddenly it is working! 🙂
Hi Ivan
Your data model is wrong
Dimension should not be referencing Dimension
Try this classic star schema ...
DIM_Products
- Product ID
- Product Name
- Product Category
- Product Brand
DIM_Locations
- Location ID
- Location Name
- Location Country
Fact_Stock
- Product ID
- Location ID
- Qty
Then addrelationships
DIM_Products[Product ID] 1:M Fact_Stock[Product ID]
DIM_Locations[Location ID] 1:M Fact_Stock[Location ID]
Thanks for reaching out for help.

Hi @speedramps ,
this model is pretty complicated as I have FACT_Tasks with "RelatedToID" field. And under this field it can be DIM_Locations, DIM_Deals and DIM_Products. And all of the DIM tables have Location name. And I need to get that into FACT_Tasks.
However, the question is still why LOOKUPVALUE is not able to find matching location without having active relationship.
