Looking for an expression to solve conditional counting issue

[#1]

I am trying to create an expression but i have no idea, if i count the OUT_OF_STK_FLG i get 35, but I don't want count the flag if the OUT OF STOCK DAYS has not changed, in other words than this value is redundant. The result should be 25 instead of 35.

I added an additional column STOCKOUT FILTER and added manually the values and made a SUM, so you can see which row should not be counted for OUT OF STK FLG.

Any Ideas? I am thing of AGGR function, but how?

Hi, try the next:

Count ([STOCKOUT FILTER])

or

Count({$<[STOCKOUT FILTER]={‘1’}>}  [OUT OF STK FLG])   --> Best

Or

Count(if([STOCKOUT FILTER]=’1’, [OUT OF STK FLG]))

I recommend you to open the help page and look for Set Analysis

When loading, in order to have your flag column:

TABLE:

LOAD

[OUT OF STK FLG],

……………………..

IF(PREVIOUS([OUT OF STK FLG])= [OUT OF STK FLG],’0’,’1’))     AS  "STOCKOUT FILTER",

FROM … origin

Order by DSS_DATE.DAY_DT

You may correct syntax.

The STOCKOUT_FILTER value was added from me and was a helper to understand the problematic. This value is not available, so we cannot use it.

The solution withe the PREVIOUS is a good idea as long as the sorting is correct. In the meantime I found a different solution, the fact is that I may calculate the max(OUT OF STK DAYS) minus the min(OUT OF STK DAYS) + 1 if [OUT OF STK FLG]=1.

Thanks anyway for your help.
