My pivot table shown above.

AREA = SUM(IF(STATUS='ACTIVE', IF(FLAG='A'OR FLAG='R',(RECIEVABLE-RECEIPT_AMT))))

LOAN = IF(STATUS='ACTIVE', LOAN_AMOUNT)

NO_OF_INS = RANGESUM(AREAS)/INS_AMT

I want to remove the negative and null values from the resulted table. so How can I modify my expressions to do the same?

Thanks in Advance.

Priyantha.

May be try,

AREAS = SUM(IF(STATUS='ACTIVE' And RECIEVABLE-RECEIPT_AMT>0 , IF( FLAG='A' OR FLAG='R' ,(RECIEVABLE-RECEIPT_AMT))))

LOAN = IF(STATUS='ACTIVE' And AREAS>0, LOAN_AMOUNT)

NO_OF_INS = If(AREAS>0, RANGESUM(AREAS)/INS_AMT)

Maybe you just do this..

Try this..

AREA = alt(SUM(IF(STATUS='ACTIVE', IF(FLAG='A'OR FLAG='R',(RECIEVABLE-RECEIPT_AMT))))*-1, 0)

LOAN = alt(IF(STATUS='ACTIVE', LOAN_AMOUNT)*-1, 0)

NO_OF_INS = alt((RANGESUM(AREAS)/INS_AMT)*-1, 0)

Although I can this has been answered, but is there a reason you are not using set analysis here?

AREA = Sum({<STATUS = {'ACTIVE'}, LOAN_NO {"=RECIEVABLE-RECEIPT_AMT > 0"}, FLAG = {'A', 'R'}>} RECIEVABLE-RECEIPT_AMT)

LOAN = Only({<STATUS = {'ACTIVE'}, LOAN_NO {"=RECIEVABLE-RECEIPT_AMT > 0"}>} LOAN_AMOUNT)

NO_OF_INS = I guess this can stay the same (not sure what is going on here

Sunny,

I agree with all of your point and thought the same when I posted the answer. Believe me, I expected your reply and thought to update my post with set expression. But decided to leave as it is (OP marked the solution as correct).

I am not sure about the last expression and field "INS_AMT". So I have added the "If" Condition, to be on the safer side.

Did not mean to say that your solution is incorrect, I am sure it works (and in fact in some case this might be the only solution because of data coming from different tables) But I thought why not look for a way to improve it using set analysis if it is possible

No. I knew that my solution woks fine. I thought to change the expression from "If" to Set analysis like you mentioned.

Hi , Tamil,

your expression works but results changed as unexpected. I mean not only negative values and null values removed but also changed the positive values unexpectedly.

Thaks for the try.

Priyantha,
