File: m2/latest/userguide/ba-runtime-error-codes-s.md

Summary

Adds two new SQL error codes covering failure to load deduplication keys and deduplication abort due to exceeding the maxDedupKeys limit.

Security assessment

These are new data-deduplication error messages describing operational limits and failure conditions; no security control, vulnerability, or credential handling is referenced.

Evidence

+`BA-S0010` | Error | Deduplication aborted for table '`%s`': existing row count (`%d`) exceeds maxDedupKeys limit (`%d`). Increase the maxDedupKeys limit or disable checkDuplicatesOnAppend. |
