R3482 Generation Date in the Past date in JD Edwards 9.2

EnterpriseOne Tools Release:  9.2.7.3

We have some issues running the R3482 generation date with the date in the past instead of keeping the Generation date blank which is todays date . The client informed that this was giving correct results in One World Xe .

However in Enterprise One 9.2 if the Generation date is kept as 15th June 2023 (06/15/2023) instead of today date ( 12 /12./2023 ) . After the R3482 is run the start date in the MRP message is shown as 06/15/2023 when the requested date is less than todays date . The Start date is not calculated based on the Lead Level set in the Item Branch .The Recommended start date also come the same . This is for both Purchase or work orders .
