Data becomes incorrect after first incremental update

[Jean_Ferro]

This is driving me crazy. I created a data model and incrementally updated the main table in fact.

When I update the data on the desktop the information is correct, when I publish it remains correct but after publishing the power bi service starts doing the first historical incremental update and when finished it specifically messes up this data:

Correct data on desktop

Wrong data after first incremental refresh

Native query is ok on all steps.

And I don't even get the warning that power by can't check whether query M is foldable, so it seems like everything is correct.

Does anyone have any suggestions.

Best regards.

More information about the problem.

I isolated the values to see where specifically the problem was, I discovered that when PBI updates with the table configured for incremental, the first day of each month the value is duplicated as in the example below:

Without incremental first incremental refresh

After first incremental refresh

My native query:

select "_"."ID_EMPRESA",
"_"."DATA",
"_"."ID_FILIAL",
"_"."CONTA",
"_"."NATUREZA",
"_"."HISTORICO",
"_"."VALOR",
"_"."CENTRO",
"_"."DTAEMISSAO",
"_"."USUINCLUSAO",
"_"."SEQFORNECEDOR",
"_"."VALORCAL"
from "CONSINCO"."PASV_PBI_LANCAMENTOS" "_"
where "_"."DATA" >= to_date('2024-01-01 00:00:00', 'YYYY-MM-DD HH24:MI:SS')
and "_"."DATA" <= to_date('2024-04-19 00:00:00', 'YYYY-MM-DD HH24:MI:SS')

EDIT:
I created a table in the database with 2 rows January 1 and February 1, with a value of 1000 and 2000, after an incremental refresh it duplicated the value.

Select on DB

PBI after incremental refresh

Native Query:

select "_"."DTA",
"_"."VALOR"
from "CONSINCO"."PAS_TESTE" "_"
where "_"."DTA" >= to_date('2024-01-01 00:00:00', 'YYYY-MM-DD HH24:MI:SS') and "_"."DTA" <= to_date('2024-12-01 00:00:00', 'YYYY-MM-DD HH24:MI:SS')

Only one of the parameters can be inclusive, usually RangeStart.  Change your formula to 

select "_"."DTA",
"_"."VALOR"
from "CONSINCO"."PAS_TESTE" "_"
where "_"."DTA" >= to_date('2024-01-01 00:00:00', 'YYYY-MM-DD HH24:MI:SS') and "_"."DTA" < to_date('2024-12-01 00:00:00', 'YYYY-MM-DD HH24:MI:SS')

That was the problem! Thank you, I would never have imagined that!

Maybe check the Time difference between service and desktop. Power BI service works on UTC time and not local time.

Show your query. Most likely the RangeStart/RangeEnd filter is set incorrectly.
