Assigning let variables to WHERE statement using DATA NULL - sas

hi I am trying to use DATA NULL step to assign value to variable based on different criteria. This variable from NULL statement will be assigned to WHERE statement in the following DATA step.
Ideally if I run it today(Thursday which is 5) the code should return 30APR2019 for both the variables. But my code throws only the variable value in the LAST-IF- statement.
data _null_;
if weekday(today()) = 5 then do;
%let exc_st_day = '30APR2019'd;
%let exc_en_day = '30APR2019'd;
end;
else if weekday(today()) = 6 then do;
%let exc_st_day = '01MAY2019'd;
%let exc_en_day = '01MAY2019'd;
end;
else if weekday(today()) = 2 then do;
%let exc_st_day = '02MAY2019'd;
%let exc_en_day = '02MAY2019'd;
end;
else if weekday(today()) = 3 then do;
%let exc_st_day = '03MAY2019'd;
%let exc_en_day = '03MAY2019'd;
end;
else if weekday(today()) = 4 then do;
%let exc_st_day = '04MAY2019'd;
%let exc_en_day = '06MAY2019'd;
end;
%put &exc_st_day &exc_en_day;
run;

You need to use CALL SYMPUTX() to create macro variables, not %LET within a data step.
if weekday(today()) = 5 then do;
call symputx('exc_st_day', '30APR2019'd);
call symputx('exc_en_day', '30APR2019'd);
end;

Macro code is evaluated BEFORE the SAS code that it generates runs. So you told SAS to run this code:
%let exc_st_day = '30APR2019'd;
%let exc_en_day = '30APR2019'd;
%let exc_st_day = '01MAY2019'd;
%let exc_en_day = '01MAY2019'd;
%let exc_st_day = '02MAY2019'd;
%let exc_en_day = '02MAY2019'd;
%let exc_st_day = '03MAY2019'd;
%let exc_en_day = '03MAY2019'd;
%let exc_st_day = '04MAY2019'd;
%let exc_en_day = '06MAY2019'd;
%put &exc_st_day &exc_en_day;
data _null_;
if weekday(today()) = 5 then do;
end;
else if weekday(today()) = 6 then do;
end;
else if weekday(today()) = 2 then do;
end;
else if weekday(today()) = 3 then do;
end;
else if weekday(today()) = 4 then do;
end;
run;
If you want to create macro variable values from a data step use the CALL SYMPUTX() function. Or if your really need to insert leading and/or trailing spaces into the macro variable value use the older CALL SYMPUT() function.

If statement in SAS macro not always working

I'm relatively new to SAS coding, and I'm trying to write this (see the whole code down below) macro that should evaluate performances (to_worse, to_better, recoveded, etc.) of several teams.
The problem is that this rule here:
if team_&y.="&PROVIDER." and team_&i. eq "" and balance_&i. = 0 then do; regolarizzato = "regolarizzato"; end;
else if team_&i. ne team_&y. and team_&y. eq "&PROVIDER." and team_&i. ne "" then do; to_worse="to_worse"; end;
else if team_&i. = team_&y. and team_&y. eq "&PROVIDER." and balance_&y. > balance_&i. then do; to_better = "to_better"; end;
does not seem to be always properly wowking; it works most of the times, but not always, and I don't understand the reason why it's failing sometimes. Could any kindheardted fella please explain why this happens? Thank you so much in advance!

The macro that is generating that IF statement seems to have few issues.
First the macro variable Y is always going to be 0 since it is set to %eval(1-1). Did you intend Y to always be one less than I? If so move that %LET statement inside the %DO loop.
Second you keep reading and writing the same dataset over and over. You should probably move the %DO loop so that it can all be done with one data step.
%macro to_worse;
%local i y ;
data COSTI_&PROVIDER.;
set COSTI_&PROVIDER.;
%do i = 1 %TO &giorno.;
%let y = %eval(&i.-1);
if team_&i. eq "" and team_&y. eq "&PROVIDER." and balance_&i. = 0 then regolarizzato = "regolarizzato";
else if team_&i. ne team_&y. and team_&y. eq "&PROVIDER." and team_&i. ne "" then to_worse="to_worse";
else if team_&i. eq team_&y. and team_&y. eq "&PROVIDER." and balance_&y. > balance_&i. then to_better = "to_better";
%end;
run;
%mend to_worse;
And finally your set of IF/THEN/ELSE conditions do not cover all of the possible combinations of values of TEAM_&I, TEAM_&Y, BALANCE_&I and BALANCE_&Y. Are you sure that the situations where you think it is not doing what you want are not just the situations that fall into one of those uncovered combinations?

How can I transform this code into macro?

So I'd like to do a macro code mixed with proc sql and data step. I have the following code in SAS:
data work.calendar;
set work.calendar;
if business_day_count^=-1 then do;
num_seq + 1;
drop num_seq;
business_day_count = num_seq;
end;
else
business_day_count = -1;
run;
I'd like to put it into macro code, but it doesn't work.
My macro code:
%macro1();
data work.job_calendar;
set work.job_calendar;
%if business_day_count^=-1 %then %do;
num_seq + 1;
drop num_seq;
business_day_count = num_seq;
%end;
else
business_day_count = -1;
run;
%mend;
The whole code is:
%macro update_day(date);
proc sql;
update work.job_calendar
set business_day_count =
case when datepart(calendar_date) = "&date"d then -1
else business_day_count
end;
quit;
proc sql;
update work.job_calendar
set status_ind =
case when business_day_count = -1 then 'N'
else status_ind
end;
quit;
proc sql;
update work.job_calendar
set rundate_ind =
case when business_day_count = -1 then 'N'
else status_ind
end;
quit;
proc sql;
update work.job_calendar
set daily_rundate_ind =
case when business_day_count = -1 then 'N'
else status_ind
end;
quit;
proc sql;
update work.job_calendar
set weekly_rundate_ind =
case when business_day_count = -1 then 'N'
else status_ind
end;
quit;
proc sql;
update work.job_calendar
set monthly_rundate_ind =
case when business_day_count = -1 then 'N'
else status_ind
end;
quit;
data work.job_calendar;
set work.job_calendar;
if business_day_count^=-1 then do;
num_seq + 1;
drop num_seq;
business_day_count = num_seq;
end;
else
business_day_count = -1;
%mend;
The error code is: ERROR 180 - 322 Statement is not valid or it is used out of proper order. I don't know what I'm doing wrong.
You're mixing data step and macro code. Not sure what you're trying to achieve so no idea on what to propose but removing the %IF/%THEN will allow your code to work.
%macro1();
data work.job_calendar;
set work.job_calendar;
if business_day_count^=-1 then do;
num_seq + 1;
drop num_seq;
business_day_count = num_seq;
end;
else
business_day_count = -1;
run;
%mend;
%macro1;
Here is a tutorial on converting working code to a macro and one on overall macro programming.
To define a macro you need to use the %MACRO statement. Also why did you change lines 3 and 7 from data statements to macro statements?
That code cannot work. First the %IF is always true since the string business_day_count is never going to match the string -1. Second you have an else statement without any previous if statement.
Try something like this instead.
%macro macro1();
data work.job_calendar;
set work.job_calendar;
if business_day_count^=-1 then do;
num_seq + 1;
drop num_seq;
business_day_count = num_seq;
end;
else business_day_count = -1;
run;
%mend macro1;

Required Operator not found in Expression:

In the below code, I'm using macro variables in then statement, however any variation of code seems to be failing in one or the other.
%MACRO LOOP_I;
DATA JAV_WORK2;
set WORK.JAV_WORK1;
%do i = 1 %to 24 %by 1;
%IF FF in ('CV', 'CV1', 'CV2', 'CVA', 'CVP', 'HAS') and S_TYPE in ('ETR_CARD', 'ETR_PCP', 'ETR_TRX') %THEN MONTH&i_SALES=trx&i;
%ELSE %IF FF = 'HAS' and LENGTH(GEO_ID) = 6 and S_TYPE = ('ETR_DDD') %THEN MONTH&i_SALES= UNIT&i;
%end;
RUN;
%MEND LOOP_I;
%LOOP_I
When I tried removing % from IF statements, then I was receiving "ERROR 180-322: Statement is not valid or it is used out of proper order". TIA
You can achieve the same results using arrays instead of macro loops.
data jav_work2;
set jav_work1;
array sales_month[24];
array trx[24];
array unit[24];
if(FF IN('CV', 'CV1', 'CV2', 'CVA', 'CVP', 'HAS')
AND S_TYPE in ('ETR_CARD', 'ETR_PCP', 'ETR_TRX')
then do;
do i = 1 to 24;
sales_month[i] = trx[i];
end;
else if(FF = 'HAS' AND length(GEO_ID) = 6 AND S_TYPE = 'ETR_DDD') then do;
do i = 1 to 24
sales_month[i] = unit[i];
end;
end;
end;
run;
If you wanted to use the same naming convention, you can enclose it within a macro and modify the sales_month[24] array statement with this:
array sales_month[24] %do i = 1 %to 24; month&i._sales %end; ;

Create a variable inside WHEN-DO statement SAS

Want to create 2 macro variables "list" and "list2" depending on prod's value but it always returns the last iteration values.
Thanks
%let prod=WC;
SELECT ;
WHEN (WC = &prod)
DO;
%let list = (60 , 63 );
%let list2= ("6A","6B","6C") ;
END;
WHEN (MT = &prod)
DO;
%let list = (33 , 34);
%let list2= ("3A","3B");
END;
OTHERWISE;
END;
RUN;
``
The macro processor works before the generated code is passed to SAS to interpret. So your code is evaluated in this order:
%let prod=WC;
%let list = (60 , 63 );
%let list2= ("6A","6B","6C") ;
%let list = (33 , 34);
%let list2= ("3A","3B");
data ...
SELECT ;
WHEN (WC = &prod) DO;
END;
WHEN (MT = &prod) DO;
END;
OTHERWISE;
END;
...
RUN;
To set macro variables from a running data step use the CALL SYMPUTX() function. Also are you really trying to compare the variable WC to the variable MT? Does the data in your data step even have those variables? Or did you want to compare the text WC to the text MT?
when ("WC" = "&prod") do;
call symputx('list','(60,63)');
call symputx('list2','("6A","6B","6C")') ;
end;
Use call symput in a datastep:-
Call symput in SAS documentation
So your statements will be something like:-
call symput("list", "(60 , 63 )");
Hope this helps :-)

Loop between dates

I created below macro to generate few datasets based on date macro.
%macro pull(date);
proc sql;
create table new&date as
select * from acct
where date=&date.;
quit;
%mend;
So if i want to create dataset for 20170101 20170201 20170301 20170401 20170501, all i can do is use below macro
%macro pull(20170101)
%macro pull(20170201)
%macro pull(20170301)
%macro pull(20170401)
%macro pull(20170501)
What i am planning now is create two macro variables
%let begin=20170101;
%let end =20170501;
and create datasets based on begin and end using loop. Is it possible to do that.So what i am trying to do is give start and end date as macro variable and pull records between begin and end date from acct dataset and create separate datasets for each month between start and end dates
Note dataset have monthly dates for each year.
Below is the code i am trying
%let beg="01jan2000"d;
%let end="01jan2001"d;
%macro Test;
%do date=&beg. %to &end.;
proc sql;
create table IPw_&date. as
select *
from sample
where date=&date. quit;
%end;
%mend;
%Test;
When date information must be inferred from values that are not SAS date values you will need to input the information to get a date value, and put the values iterated over to get the desired non date representation.
This example demonstrates
INPUTN function to parse the YYYYMMDD arguments into date values using informat YYMMDD8.
INTNX function to compute 1st of the month of the date values
PUTN function to convert a date value to a YYYYMMDD representation using format YYMMDDN8.
%DO %WHILE statement for iterating
INTNX function to advance the iteration variable to the start of the next month
Code
%macro pull(yyyymmdd);
%local out;
%let out = pull_&yyyymmdd;
data &out;
pull_date = input ("&yyyymmdd", yymmdd8.);
format pull_date yymmdd10.;
