Unable to override line price using OM extensions

Summary:

Hi,

I have some issue using OM extensions to automatically override sales order lines price.

It seems that this functionality is not supported by 23C version, but I need to somehow override the unit selling price of my lines.

Is there any other way to do so?

Thanks for you help.

Kindly Regards,

Federico.
