Good afternoon!

I am having difficulties in a crystal report and I hope you can help me.! hehe

I have the field "Period" type numeric. Example = 201306
it is the year and month along as you can see.
This field will filter the report, I need to create a formula that when the user enter the "Period" it shows the previous twelve months.
Example user enters 201306 the report shows:

201305 201304 201303 201302 201301 201212 201211 201210 201209
201208 201207 201206

how to do it? another and how do I get the data that have to be the same for the months?

Hi Carine,
 
Use the below formula to show the previous 12 months
 
Numbervar Yr :=ToNumber(Left({?My Parameter},4));
NumberVar Mn :=ToNumber(Right({?My Parameter},2));
Numbervar i:=0;
Datevar dt:= Cdate(Yr,Mn,1);
StringVar tt:="" ;
for i :=1 to 12 do
tt:= tt+ Totext(Year(dateadd("m",-i, dt)),0)&Totext(Month((dateadd("m",-i, dt))),0)+CHR(32);
tt;
 
 
P.S: Replace the {?My Parameter} field with your YearMonth input field.
The above formula will shows all the previous YearMonth values in a single Text box,
if you want to treat those values as separete then you need to load those values to an Array based on Space(chr(32)) value.
