SAP MDG CLass Characteristics Derivations Not working after Service pack updating from 9 to 12

[pangas3]

Hi All,

we are running on SAP MASTER DATA GOVERNANCE 9.2  and EHP8 FOR SAP ERP 6.0 with HDB Support pack 9.

After the implementation of the Support Packs 10, 11 and 12 on the SAP System we are facing issues like

• Derivations done using BADI USMD_RULE_SERVICE_CROSS_ET with Derive method  for Class Characteristics not working as Previous 
• When creating new materials we automatically assign classes based on the CR type and Material Group Some single value characteristics are duplicated on the UI screen and  causing fatal errors when saving.

When saving the CR some characteristic values disappear from the UI screen but the entered values remain present in the staging tables 

Any Inputs?

Thanks,

Panga
