Problem with If instruction

[Anonymous]

Dear all,

I'm becaming crazy. How don't understand where is my mistake

 IF (sum({<MY_YEAR={$(=Only(MY_ANNO-1))}>} MY_SALES) = 0,1, MY_MARGIN/sum({<MY_YEAR={$(=Only(MY_ANNO-1))}>} MY_SALES))

By the script above, I would obtain the following scenario:

if sum( ..... MY_SALES) = 0 , put MY_MARGIN = 1, else do the margin calculation.

But it doesn't work

Help please

Thanks in advance

I don't see anything wrong with it. If you select a value for MY_ANNO then you should get a result as long as there is data where MY_YEAR = MY_ANNO - 1

Without knowing your data structure, I guess you should add some operation to MY_MARGIN field except it returns one value only. Otherwise you cannot divide an array of possible values by a unique SUM() of any other field.

Also, try using the ONLY() function with just the field as parameter, keeping the "-1" outside.

Let us know if the following expression works fine:

IF (SUM({<MY_YEAR={$(=ONLY(MY_ANNO)-1)}>} MY_SALES) = 0,

     1,

     SUM(MY_MARGIN)/SUM({<MY_YEAR={$(=ONLY(MY_ANNO)-1)}>} MY_SALES)

)

Regards.
