Not a legal OleAut date..
Getting the following error while refreshing from an Oracle DB using the Gateway refresh...

The dataset is absolutely fine as the "on-demand" refresh goes through just fine. Its the scheduled refresh that has problems. Any ideas??

Thanks Anonymous for your post! You helped me out.
I had the same error message. And indeed some of my dates ware having strange values, like 01-01-0015 and 01-01-0215. These should have been 01-01-2015. After I changed the data the refresh worked.
In my case these dates were not used in a relationship.
(I wanted to add to this, in case other people google this and find this...)
The messed up years were proving to be the issue for me, too. Fortunately, there were only a few (0997 should have been 1997, etc.). And I was able to add some steps to the query to replace the values with the correct date. This kept me from changing column number types back and forth.

I solved this problem!
It was a date that I used in a relationship called DueDate, I found a value that was 05/05/0016 and this value was causing traoubles on scheduled refresh.
So, look all your date values, try sorting and checking de min and max value of each field.

Hi Rodrigo,
This solved my problem after a few attempts. Saved the day.
This problem should be marked as solved.

Hi,
I had almost the same issue with an ODBC connection to a Progress Database. Everything works fine in Power BI Desktop but was not able to refresh once uploaded to a group.
I've applied the following work around and it works for me:
1. Go to the query designer
2. Transform the Date field(s) to a number field
3. Add another step in the Query editor
4. Set the number field back to the desired Date field.
Now i'm able to schedule and run the refresh.
I am also receiving this error - Not a legal OleAut date.. - with scheduled refresh only (on-demand refresh works fine).
mravestein - Can you please clarify the steps that you describe?
I went into desktop Power BI and changed the data type using the dropdown depicted below.
Number options were: Decimal Number, Fixed Decimal Number, Whole Number - I tried a few different ones.
My field is actually date/time so I I changed it back to that.
a) Am I making the changes in the correct place
b) Which numeric data type should I choose
c) I am not clear what you mean by step #3 (Add another step in the Query editor)
I'm new to Power BI so I appreciate any assistance you can offer.
Hi, Plysko,
By step #3 I ment, an additional step in Power BI (for example rename a column).
If you change a type, and then change it again, PowerBI only applies the last action.
for example:
Column value = 3/3/2016
If I change the type to whole number, it will be something like 21345674 (its quite random to me)If I then change the type back to date the column looks good to me, but I still get the error. Power BI ignores the change to Whole Number
I did:
Change type to "whole number"
Renamed a column
Change type to "date"
This fixed my error.
See below for the applied steps (Type gewijzigd = Changed Type in the Dutch language)
This has been a very frustrating few days before and after Christmas figuring out why a dataset refreshes fine in Power BI Desktop but fails on the cloud service with the useless message "The gateway operation has been cancelled explicitly by the user or from a timeout." On another message thread for that language, there were suggestions about gateway issues and join cardinality, so all our time was spent chasing down that route. It took me rebuilding the dataset from scratch one table at a time, publishing to the service each time I added a table, then refreshing from the service, to find the culprit table, but I was still getting the wrong "timeout" message. So I created a dataset with just the one faulty table, and the error message finally changed to the helpful "not a legal OleAut date" message. Then, thanks to you guys, it was a quick fix to handle years 0016 and 0017 from the ERP.
I cannot thank you all enough...was tearing my hair apart
Didnt understand why query would run on sql , refresh locally and then fail in the gateway
it was indeed dates
Thanks again
Solution:
I had the same issue
Data source error: Not a legal OleAut date.. The exception was raised by the IDataReader interface. Table: ... In my case the issue of updating data set was:
in one table with Customers data we had birthday date - in date format obviously.some of dates were incorrectly filled with data earlier than 1/1/1900 (for example "1/30/0992"
after filtration of the filed issue disapired.
looks like it some data filed parameter - which doesnot read that type of dates.
hope that helps
It sounds like you're encountering an issue with the scheduled refresh related to the Oracle DB. This error often appears when there's an issue with the date format or time zone mismatch in the database or the system's configuration. Double-check the date/time settings on your Oracle DB, especially for the scheduled refresh times.
Additionally, for any related records or lookups, if you're working with Florida arrest and jail records, you may find the Arrests FL Records helpful for reference. It provides detailed data on FL arrest searches, court records, and public arrest information.
- It seems like the issue you're encountering might be related to the date format or a mismatch in the database's expected values during the scheduled refresh. To troubleshoot, I recommend checking the time zone settings and ensuring that the "OleAut date" format is being handled correctly for your refresh schedule.
For those looking for more insights into local legal data or records, you can explore resources like the Arrest data Lynchburg to get a detailed overview of public records and arrest information in the area. This might offer useful context for handling date-related issues or similar queries.
It seems like you're running into issues with the scheduled refresh in Oracle DB using the Gateway. While the "on-demand" refresh works fine, the error may be related to the scheduled task configuration or timing issues with the Oracle DB itself.
