MDG-C Update of one custom entity is not working

Hi,

I am having one issue in MDG-C. I have created one new custom entity in company code. For that I have created the handler class and Genil model class. The new records are getting created and distributed correctly in MDG & ECC. When I am updating the existing record, its not working.

Could you please help me where to dig.

I also have one question. How I debug the handler class after final submission of my request as its not possible. I put in all methods but unfortunately the break points are not getting trigerred.

Any clue is welcome.

Thanks in advance.

Regards,

Pranab
