Hi Amar,
I've already done the above mentioned steps. From cockpit, I've executed - 'Reset all objects and Setting for a table' from Processing Steps tab. Later, I've scheduled it for loading only. Laoding was successfull. Later, I changed it to replication, It goes through the same issue.
How did you solve your issue after refreshing ECC system?. Did you follow the same steps mentioned above?
Regards,
Dev
