Hi ,
No, if you follow below 2 points.
Just take care all delta records and move to bw side.
Check this points.
1. Clear SMQ1/SM13 by using V3 jobs
2. Clear RSA7 by running delta info pack 2 times.
if possible lock ecc respective t codes. Do the changes and move to prod.
Then there won't be any problem regarding delta.
Thanks
