I want to remove:

Obs1 and 2 because they cancel eachother out (buy and return) but not 3 (repurchase)

Obs4 is a standalone item purchase, it stays

Obs5 and 6 are removed (buy and return)

Obs6 and 7 stay (two identical purchases, not purchase and return)

Obs8 stays, standalone purchase.

Ok, that seems a lil complicated.

I edited the program to fit the data but I am getting a lot of errors. I made a new field called JE_ID to fix problems with another fields which is additional here

Program:

PROC SORT DATA = SASDATA.Q1Q2_SALES;

BY _ALL_;

RUN;

DATA SASDATA.Z_Q1Q2_SALES;

IF 0 THEN MONETARY_AMOUNT=0;

DECLARE HASH HA(DATASET:'SASDATA.Q1Q2_SALES WHERE=(MONETARY_AMOUNT>0))');

HA.DEFINEKEY('OPERATOR','JOURNAL','LINE__','UNIT','ACCT','DEPARTMENT','DATE','JOURNAL_LINE_DESCRIPTION','JE_ID');

HA.DEFINEDATA(ALL:'Y');

HA.DEFINEDONE();

DO UNTIL(DONE);

SET SASDATA.Q1Q2_SALES END=DONE;

BY OPERATOR JOURNAL LINE__ UNIT ACCT DEPARTMENT MONETARY_AMOUNT DATE JOURNAL_LINE_DESCRIPTION JE_ID;

IF FIRST.DEPARTMENT AND HA.FIND()=0 AND SUM(OF MONETARY_AMOUNT)>0 THEN OUTPUT;

IF LAST.DEPARTMENT AND LAST.JOURNAL_LINE_DESCRIPTION AND NOT(FIRST.JOURNAL_LINE_DESCRIPTION) THEN OUTPUT;

END;

STOP;

RUN;

Cant figure whats going wrong, please help

Akber, I think that you've confused matters by changing the variable names and now having one more variable than you showed in your example data.

Regardless, I still think that the methodology I proposed the other day will still be the easiest for you to manage (although it might not be the most efficient code). I may have some of the variables or ordering wrong, but doesn't the following do what you want?:

PROC SORT DATA = Q1Q2_SALES;

BY OPERATOR JOURNAL LINE__ UNIT ACCT DEPARTMENT

DATE MONETARY_AMOUNT

JOURNAL_LINE_DESCRIPTION;

RUN;

data Z_Q1Q2_SALES;

retain delete_me;

if _n_ eq 1 then delete_me=0;

set Q1Q2_SALES;

by OPERATOR JOURNAL LINE__ UNIT ACCT DEPARTMENT

DATE JOURNAL_LINE_DESCRIPTION;

set Q1Q2_SALES ( firstobs = 2 keep = MONETARY_AMOUNT

rename = (MONETARY_AMOUNT = Next_MONETARY_AMOUNT) )

Q1Q2_SALES ( obs = 1 drop = _all_ );

if delete_me then do;

output;

delete_me=0;

end;

else if not last.journal_line_description then do;

if sum(monetary_amount,next_monetary_amount) eq 0 then do;

delete_me=1;

output;

end;

else output;

end;

else output;

run;

data Z_Q1Q2_SALES;

set Z_Q1Q2_SALES;

if delete_me eq 0;

run;

hi ... if the goal is " ... simply remove TWO observations with equal Amount with a different sign, based just on amount and no other field ..." , I think this also works (using Fried Egg's data and idea similar to Ksharp's matching positive and negative values of _dllr) ... ...

ps given all the various responses, I'm not sure if this is still the problem ... if it involves looking for negative values plus matching on other variables, just change the index
