Dates in column headings

lca — Wed, 07 Mar 2012 19:07:21 GMT

Hi!

I have a macro iteration loop where I make x number of columns in a table (the table is exported to Excel/csv)..

It works, but I want to have variable dates in the column headings.

Now the column names are:

Periode_1	Periode_2	Periode_x
Data	Data	Data

I want them to be (example):

Periode: 01.01.2011 - 31.01.2011	Periode: 01.02.2011-28.02.2011	Periode:x -
Data	Data	Data

I use the INTNX function in the If Then loop, and tried to use the same function (with some combinations) as a header name but no luck.

Any ideas? 🙂

--------------------------------------------------------------

My code looks something like this:

data TableOut;
set TableIn;

%macro Report(x, y);
%do Next=&x %to &y;

%let StartDate = '01MAR2011'd;
%let EndDate = '29FEB2012'd;

%let ColName = Periode_&Next;

if Value = 0
then &&ColName = 0;

else if (StartDate >= intnx('Month', &StartDate, -&Next, 'Same') and
           StartDate <= intnx('Month', &EndDate, -&Next, 'Same') and
           EndDate   >= intnx('Month', &EndDate, -&Next, 'Same'))
then     &&ColName = (Value/(EndDate-StartDate)) * (intnx('Month', &EndDate, -&Next, 'Same') - StartDate);

else if (StartDate <= intnx('Month', &StartDate, -&Next, 'Same') and
           EndDate   <= intnx('Month', &EndDate, -&Next, 'Same') and
           EndDate   >= intnx('Month', &StartDate, -&Next, 'Same'))
then     &&ColName = (Value/(EndDate-StartDate)) * (EndDate - intnx('Month', &StartDate, -&Next, 'Same'));

else if (StartDate <= intnx('Month', &StartDate, -&Next, 'Same') and
EndDate >= intnx('Month', &EndDate, -&Next, 'Same'))
then &&ColName = (Value/(EndDate-StartDate)) * (intnx('Month', &EndDate, -&Next, 'Same') - intnx('Month', &StartDate, -&Next, 'Same'));

else if (StartDate >= intnx('Month', &StartDate, -&Next, 'Same') and
           StartDate <= intnx('Month', &EndDate, -&Next, 'Same') and
           EndDate >= intnx('Month', &StartDate, -&Next, 'Same') and
           EndDate <= intnx('Month', &EndDate, -&Next, 'Same'))
then   &&ColName = Value;

else &&ColName = 0;

%end;
%mend Report;
%Report(0,6);

run;

I want the ColName to be: Periode_01MAR2011-29FEB2012 insted of Periode_0

You do not really give enough data for me to fully understand your problem, so I made some assumptions:

data foo;

format periode_1 periode_2 periode_x date9.;

call streaminit(12345);

do i=1 to 10;

periode_1=today()-floor(rand('cauchy'));

periode_2=today()-floor(rand('cauchy'));

periode_x=today()-floor(rand('cauchy'));

output;

end;

drop i;

run;

proc print data=foo noobs; run;

periode_1 periode_2 periode_x

quit;

proc datasets lib=work memtype=data;

modify foo;

attrib periode_1 label="&label1"

run;

proc export

You can add labels to these variables, then use proc export + label to export a xls file, the label of variable will instead of the name of variable.

To better understand what it is you are trying to do please provide a more accurate representation of what the input data from TableIn in your example code is like and the expected output.
