Hi All, I need some help in getting a problem solved. I have a data like this:

 

201806201807201809201810201811201812201901201902201903201904
34243020401025185060

 

Desired Output that I am looking for:

 

  • 201806 value will go till 6 months, and from 7 month the value will be reduced to 98%, from 13th month the value will again reduced to 98% and so on. 
  • Same will happen to rest of the months

 

201806201807201809201810201811201812201901201902201903201904

Hi @ankitgupta 

 

The attached will do the trick. I've annotated the workflows to show what is happening at each stage:

Screenshot 2019-05-19 at 09.20.39.png

 

The values themselves are calculated in the multi-row formula tool, which uses the following:

 

IF [Month] = [Start Month] THEN [Start Value]
ELSEIF Mod(DateTimeDiff([Start Month],[Month],"months"),6)=0 THEN [Row-1:Value]*0.98 
ELSE [Row-1:Value] 
ENDIF

 

The Modulo function (Mod) is used to work out where the sixth months fall relative to the start date.

 

Hope this helps!

@jamielaird , thanks for replying. In the output what I need is that, after every 6 months the number should set to 98% of the original # , In your workflow you sent, the # reduced to 98% from 7 month, but once we reached in month 13 it showing null, what should we do to show...

 

Month 1 to 6 - Original # say A 

Month 7 to 12 - 98% of Original say B 

Month 13 to 18 - 98% of B

.

.

.

Month N to N - 98 % of 

 

Also the script should check if the Months going beyond current month, then it should drop the future months columns. 

 

Thanks,

Ankit

Hi @ankitgupta 

 

To only show the values from the current month and before, add a filter just before the Crosstab tool with the following expression

 

[Month] < DateTimeFirstOfMonth()

 

To mitigate the 13th month = null problem, change the Condition expression in the Multi-Row tool  to 

 

DateTimeDiff([Month],[Start Month],"months")<=100

Hi @ankitgupta 

 

You really should mark @jamielaird's answer as a solution since he answered your original post.
