Possible Tip/Trick: Dynamic Date Dimension Table
I have generate a dynamic date table but I'm not able to create a relationship with the main table where my data resides. In both tables I have the NameofMonth and the Year.
When I try to manually create the relationship I get this error. What am I doing wrong?
faacq one of the columns in a relationship must have unique values. A month name column will have the same month name appear at least 28 times. Date tables are normally linked to fact tables via the unique date column. All other columns are supplemental info about the date in question, not meant for creating relationships.
Thank you for the reply. I probably do not undestand the purpose of having a date table. I was expecting after establishing the link between my fact table and the date table, to use the slicers to filter my data in many different ways.
If establishing the relation is not needed, how can I use the date table to slice my data?
faacq you understand the purpose correctly, but not the method. You're trying to create a relationship with a month column, which is incorrect. You're supposed to create a relationship between a date column in your fact table and the main date column in the date table. Then you could use the month column as a slicer.
You are right, using the date column I managed to establish the relation. When I try to slice my data It seems that the date table does not have any effect. My fact table has a column with "Month Year" info, but still I'm not able to slice my data with the columns available in the date table.
