3254301 - Variants no longer work well after system upgrade in SAP S/4HANA Cloud Public Edition Fiori apps in Manufacturing

You're using Variants in manufacturing fiori apps such as Monitor Material Coverage or Manage Production Orders in SAP S/4HANA Cloud Public Edition. After the system upgrade, the Variants no longer work well. There are various issues such as:
1. The page keeps loading for a long time and no content is displayed.
2. The data displayed is inconsistent with the actual data in the system.

 SAP S/4HANA Cloud Public Edition

1. Open relevant apps.
2. Switch to the Variant.
3. The issues occur.

The issues always happen in Variants that are created before the upgrade. This is due to the incompatibility between the old-version Variant and new-version system.

A workaround to solve the problem is to replace the old Variant with a new-created one with exactly the same filters.
If this method can't solve your problem or meet your requirement, please open a ticket in corresponding component, such as PP-FIO-MRP or PP-FIO-SFC.
