Custom Process Types not working in SAP BPC 10.0

Hi Experts,

We have migrated from SAP BPC 7.5 NW to SAP BPC 10.0 NW.

We have three Custom Process Types created in BPC 7.5NW using the super class CL_UJD_SIMPLE_ACTOR as super class.

It has been made Obsolete and Final class in BPC 10.0NW and the Custom Process types are not running as expected.

Can you please suggest if there is any alternative for using the existing custom process types? Or do we have any alternative for creating custom process types?

*Note: We have tried replacing the superclass with CL_UJD_ACTOR instead of CL_UJD_SIMPLE_ACTOR but of no use.

Regards,

Balraj.
