Split column function - adds revenue?

Hi, I am a new user in SAS and i have encountered a problem that I need help to solve. 

 

I have an issue when using the split column function in SAS EG. 

 

I have a Data-set with the following example columns: 

 

User_ID  Segment  Product  Period      Revenue

12345     Retail        Shoes    2016-02   500

 

I would like to use the split function in order to get the period spltted into several new columns for each month of the year, instead rows. Somehow, when I perform the split column task, it adds about 20% to the total revenue. Before making the split I have used the sum function for the revenue. 

 

Can someone please tell me what I am doing wrong here? Smiley Happy

Re: Split column function - adds revenue?

Is period a date variable?  If so you wouldn't split it (which is for character strings) but rather extract the various parts using year() or month() functions.  E.g.:

data want;
  set have;
  yr=year(period);
  mnth=month(period);
run;

@RW9 Period is formated as charachter string and revenue in number format. :/

 

First I assumed that it would be better to use the "Transpose function"? But as i understood it, the transpose function is preferably used in the opposite way, whenever you would like to transpose a column into a row? It feels like i'm swimming in the deep water over here Smiley Happy haha.

All I can think is that with the extra variables its grouping the data differently.  Sorry, I don't use EG so can't be further help as I only use code.  Transpose can be used either way, normalised to transposed and vice versa.  If you have multiple variables or different types then arrays can be more effective.

Maybe you should be looking at REPORTING tasks where the variable Period has a grouping column role.
