Getting Too Many Record Using Symput Date Macros

[omega1983]

I am creating a dataset named FPD.  I pass a symput macro for the first day of the last month(LMM) and first day of this month(TMM).  I am supposed to get 6 records for February and 76 for March (in the dataset FPD).  When I run the date range by itself (ie

WHERE  LN_NXT_PMT_DUE_DT EQ &LMM. 

                           AND LN_FST_DUE_DT EQ &LMM.

I get the correct number of records. When I combine the date ranges as in the code below I am getting about 30 records more than I should.  Both the LN_NXT_PMT_DUE_DT and the LN_FST_DUE_DT must equal the beginning of the month (either February or March).  When I combine the two symput macros LM and TM, some of the LN_FST_DUE_DT are out of date range.  Here is the full code:

data _null_;

LM = INTNX('Month',Today(),-1,'b');/* 1st day last month jaj*/

TM = INTNX('Month',Today(),0,'b');/*1st day this month jaj */

%put &LMM &TMM;

DATA FPD;

Merge Data1.my_loan_daily_&pbd_date.

                           (Keep=

                                LN_NO

                                BO_BORR_FST_NM

                                BO_BORR_MDL_NM

                                BO_BORR_LAST_NM

                                LN_LOAN_MOD_DT

                           );

                     WHERE  LN_NXT_PMT_DUE_DT EQ &LMM.

                           AND LN_FST_DUE_DT EQ &LMM.   or

                          LN_NXT_PMT_DUE_DT EQ &TMM.

                           AND LN_FST_DUE_DT EQ &TMM. 

                           AND substr(LN_NO, 1, 6) NE '010790'

                           AND LN_1ST_PRIN_BA >0

                           AND LN_LOAN_MOD_DT EQ .

                           AND upcase(substr(IV_ID, 1, 1)) NE 'A';

                     BY LN_NO;

                     DROP IV_ID

                                LN_LOAN_MOD_DT

                                ;

                     Run;

Add some brackets into your where clause to separate your AND from your OR.

I'm guessing you want the following:

WHERE  (LN_NXT_PMT_DUE_DT EQ &LMM.

                           AND LN_FST_DUE_DT EQ &LMM.   or

                          LN_NXT_PMT_DUE_DT EQ &TMM.

                           AND LN_FST_DUE_DT EQ &TMM. )

                           AND substr(LN_NO, 1, 6) NE '010790'

                           AND LN_1ST_PRIN_BA >0

                           AND LN_LOAN_MOD_DT EQ .

                           AND upcase(substr(IV_ID, 1, 1)) NE 'A';

Hi Can u help me as to where i can find the book: sas macro language 1 essentials

[Reeza]

That looks like a SAS course. I'd recommend enrolling in the course or buying the book off the SAS press if its available.

The SAS Advanced Certification Guide also has a really good section on macro programming.
