Content

Hello, 

I have an issue with my offer letter in ORC. 
I fill several date field during the offer creation but the date displays in my offer letter for the preview and/or after extended is not correct. 
4 dates is important for my offer letter : The start date, the most extended date, the system date and the return contract date (flexfield). 
If I enter following data for example : 
The start date : 04/30/2020
the return contract date : 04/29/2020
The system date and the most extended date are calculated by the system. 

For all requisition tested, and old candidates, new candidate, new requisition, the data return in my job offer letter is the 4 april or the 5 april.
