UPDATE:
It seems like this issue is not resolving. Manual trigger of delta merge fail:
SAP DBTech JDBC: [2048]: column store error: merge history index
error:
[2450] error during merge of delta index occurred
Also, this query is failing:
UPDATE SAB_SLT"."VBFA" WITH PARAMETERS('OPTIMIZE_COMPRESSION'='YES');
SAP DBTech JDBC: [2048]: column store error: process parameters error: [6952] exception 6952:
