/**
 * GetTcodeUsage — read-only: was each transaction used in the last N months?
 *
 * Source: workload monitor (ST03N) monthly aggregates, read on the SAP side
 * by ZMCP_WL_TCODE_USAGE (SWNC_COLLECTOR_GET_AGGREGATES, USERTCODE). User
 * names never leave SAP — the FM returns one boolean per transaction.
 *
 * Backend: ECC only — OData FunctionImport `WlTcodeUsage` on ZMCP_ADT_SRV.
 *
 * Other system: `destination` (or SAP_USAGE_RFCDEST from the profile sap.env)
 * names an SM59 destination on the connected system; the FM then reads that
 * system's aggregates over RFC (DEV profile → QA / PRD business usage). The
 * destination is site-specific — it is never defaulted by the plugin.
