Delta no longer possible due to realignment - COPA extraction

Hello,

Yesterday morning, I did realignment of COPA data with TCODE KEND, the realignment was successful. Every night we have a process chain that load delta loads and this chain failed with the message that "Delta no longer possible due to realignment".

I am thinking of doing INIT without data transfer and not sure if I need to reset the delta in KEB5.

Does any have any idea how I can resolve it and what steps I should take in resolving it.

From the logs in KEB5, The replication status says "successful"

Thanks,

Bhat
