Solution:-

This error comes if the last transaction to the RecordStore was not fully committed prior to writing to it again to CAS process. This happens whenever BCC deployment cancels the running baseline process and restart once again.

Following are possible ways to fix this issue

1. Restarting CAS server should fix the issue.

2. Stop triggering baseline/partial doing BCC deployment.

3. Set resetActive flag to true on following components to rollback every previously active transaction

/atg/endeca/index/DataDocumentSubmitter
/atg/endeca/index/DimensionDocumentSubmitter
/atg/endeca/index/SchemaDocumentSubmitter
