If record value equals to previous then skip (script help)

[alessandrotk]

Hi!

Could someone help me build this script in Qlik Sense?

I have "price" listed on a chronological base and, if the price is equal to previous date record, it should be skipped (dismissed).

Table on the left my source data and table on the right my expected result:

Thanks!

Perhaps like this:

tmpData:
LOAD
    Product,
    Date,
    Price
FROM
    ...source_table...
    ;

Result:
NOCONCATENATE LOAD
   Product,
   Date,
   Price
WHERE
    Flag =1
    ;
LOAD
    Product,
    Date,
    Price,
    If(Previous(Product)<>Product OR Previous(Price)<>Price,1,0) as Flag
RESIDENT
    tmpData
ORDER BY
    Product,
    Date DESC
    ;

DROP TABLE tmpData;
