I have been struggling with a similar issue "[129]: transaction rolled back by an internal error: TableUpdate failed" on an AWS Hana instance (dev edition).
Is there any specific way I can break the UPDATE statement into smaller transactions? Something like a BATCH of 200,000 Rows in 179M rows table.
I was able to accomplish this by writing the update in a loop (update records for each year-month separately). Most of the times it work, but do fail randomly with same error as mentioned above. I also tried disabling auto merge, and merge manually after each smaller update - but that also doesn't work in a stable manner.
Is there a standard way of updating large tables in HANA?
