We are experiencing a date shift when customer order/IPD dates default to midnight and the order is processed between sites in different time zones.
Sites involved:
* Main order site: Central Time
* IPD order site- Eastern Time
Example:
Main order:
* Order: XXX
* Planned/Target Delivery Date: 7/10/2026 11:00 PM CDT
IPD order:
* Order: S4454336
* Site: CLE
Observed result:
The date appears to shift from 7/10/2026 to 7/11/2026 at 12:00 AM when the IPD is created for CLE. Since 7/11/2026 is a weekend, the planned delivery date is then moved to 7/13/2026.
This causes the main order and IPD order to have different delivery dates. It is also causing incorrect dates in downstream reporting.
Business impact:
Approximately 300 order lines per day are showing incorrect EST / ETA dates.
Questions:
1. Is this expected behavior in IFS Cloud 25R1?
2. During cross-site IPD creation, does IFS convert dates between site time zones?
3. Does IFS apply calendar/weekend adjustment after the timezone conversion?
4. Is there a supported configuration to prevent date-only values from shifting when the time defaults to 12:00 AM?
5. Is changing the default time from 12:00 AM to a later time, such as 8:00 AM or 12:00 PM, a supported solution?
6. Would changing all sites to the same timezone be recommended, or could that impact MRP, EDI, scheduling, shipping, or inventory transactions?
