Calendar using two dates coming from different table

[Aspiring_Developer]

Hello, i want to created master calendar using two dates coming from different tables

=======================================

Table 1 has the data from (2017 till 2020)

Table1:    //Photo-201701 format

LOAD Photo,
left(Photo,4) as Year,
Project as [Project Code]

From Source......

==================================

Table 2 Has data from 2017 till 2025

Table 2:

Qualify *
;
Unqualify [Project Code];
LOAD

Project as [Project Code],
[Calendar Year], //format of this feild is 201701

From Source.......]

Unqualify *;

1) I want to show the  single filter at front showing values from 2017 to 2025 (one single filter for entire dashboard).

2) if i make selection in filter (Year) as 2017 , it should get filtered in the other also ie calendar year

So far i have done below:

Table A:

Project & left(Photo) as %Key_Year

From Source...

Table B:

Unqualify *;

Qualify %key;

Load 

Project & [Calendar Year] as % Key_Year

From Source...

Unqualify *;

And it works 

But should i show the single filter at front end. Please suggest
