Current Year vs Last Year

Hi 

I have attached a sheet with data represented in seasons. 

The expression for the measure is: sum({<Year={$(vMaxYear)}>} [Nett Sale Qty]).

So a bit of context, every year has two seasons, summer and winter. Eg: 2017 (W17, S17), 2018(W18, S18)

What will my expression be if i choose W18 as my current year and want to return W17 as my last year?

Also if I choose W17 & W18 together and want to return W16 & W15?

I think it would be easier for you to do this if you create a new field where you assign a numeric value to W and S. Example -

W17 = 117
S17 = 217
W18 = 118
S18 = 218

So, essentially W = 1, and S = 2

Now when you select W18 which is 118, you can simply do 118-1 = 117 in set analysis like this

{<FieldNameText, FieldNameNum = {"$(=Max(FieldNameNum) - 1)"}>}

Hi Sunny

Thank you for your reply.

Could you show me how to Set W=1 and S=2?

Also, will this work if I choose two season and want the value of the previous two seasons to be returned?

How exactly are you loading your data? Can you share the script? It can work when you select multiple rows, but you will have to program it like that....

I've only pulled in these qvds in my Qliksense App. I have not made any manipulations to the script.

The field that pertains the W17, S17, etc is called "Style Season Code" and

the measure that I want to use is "Nett Sale Qty".

May be just do this

MappingLoad:
Mapping
LOAD * INLINE [
Text, Number
W, 1
S, 2
];

and then add MapSubString...

Products:
LOAD
"SK SKU No",
"Pdiv Id No",
Division,
Department,
"Class",
Subclass,
Style,
SKU,
"Style Season Code",
MapSubString('MappingTable', "Style Season Code") as "Style Season Code Num",
"Colour Description",
Size
FROM [products.qvd](qvd);

My bad, change the MappingLoad to MappingTable:

MappingTable:
Mapping
LOAD * INLINE [
Text, Number
W, 1
S, 2
];
