## Individual table for values in an existing table

I have a table that has 20 items that show the variance between the estimate and actual cost of a project. Each item has it's own table that breaks down the costs for each project resulting in 20 individual tables. How can i go about dynamically switching between the 20 individual tables?

Show some sample inputs for 20 items table and one or two of other project table to better understand the data.

You should look into dimension modelling to kind of separate Dimension and facts.

This is the Main Table. Each "WR Number" has it's own table breaking down the costs.

Table below is an example of what each individual table looks like.

Your main table should only holds the below.(As a Dimension)

WR Number,WR Required start Date,WR Firld Complete date, WR Work Category

You should also populte WR Number(If not already) for each of the other tables and merge them into a single fact table. Create an index if necessary.

Define a relationship between the two based on WR Number.(1 to Many)

All the other columns such as WR Est Loaded Cost,Actual Loaded Cost, Loaded Cost Variance should be measure if you have the underlying data and calculations to populate them from fact table. Otherwise it doesn't hurt to keep them in dimension.

Please post if you have any questions.  Sample data is better than a picture of sample data for us to work with.

If this helps, mark it as a solution.

Kudos are nice too.

So add a column "WR Number" on each of the individual tables?

Yes. Add them to individual tables and append them togeather.

Like this? Each table will have it's own WR Number.
