Merging two slicers with field parameters

Hi, UditJ 

Based on your description, I have created the following sample data:

I created two field paramertes as shown in the image below:

I'm using these two parameters in the table visual, as shown in the following image:

I created a sync column with the following DAX:

Sync column =
SWITCH (
    'Previous Value'[Previous Value],
    "Previous Month CPM Value", "CPM",
    "Previous Month CTR Value", "CTR",
    "Previous Month VCR Value", "VCR",
    "Previous Month CPC Value", "CPC"
)

The following relationship is established between the two parameter tables:

Here are the results:

When I select the option for one of the slicers, both columns are updated at the same time. I've provided the PBIX file used this time below.
