debug-slow-sql

Find the root cause of a slow ABAP SQL or Fiori-Elements OData request and propose the cheapest fix — GUI-free via ARC-1 (odata_perf sap-statistics timing split, cds_sql "Show SQL", SAPQuery execution metrics, ST05 SQL-trace control, ABAP profiler traces), escalating to SAP GUI / HANA only for trace records and execution plans. Use when a report, transaction, Fiori list, CDS view, or OData entity is slow, a query times out under load, or someone asks "why is this SQL/OData so slow" or "where is the time going".
