## 1. Transport Management (STMS) ### Landscape Configuration Standard 3-system landscape: DEV → QAS → PRD - Each system has a system ID (SID) and client(s) - Transport routes: consolidation route (DEV→QAS) + delivery route (QAS→PRD) ### Transport Request Types | Type | Description | Client-specific? | |------|-------------|-----------------| | Workbench | Repository objects (programs, tables, classes) | No — system-wide | | Customizing | Client-specific IMG settings | Yes — per client | | Transport of Copies | Copy objects without releasing original | No | ### Transport Workflow ``` SE09 / SE10 (create / display request in DEV) → Release task → Release request → STMS (QAS): import queue → import → STMS (PRD): import queue → import (after QAS sign-off) ``` ### Common Transport Errors | Return Code | Meaning | Fix | |------------|---------|-----| | RC=0 | Success | — | | RC=4 | Warnings | Review log — usually OK | | RC=8 | Errors | Check transport log → fix object issue | | RC=12 | Syntax error | SE38 in target system → check syntax | | RC=16 | Fatal error | Check STMS log → object conflicts | **Object locked by another request** → SM12 → check table TRDIR or object name → identify locking request → coordinate with owner **Import conflict** (object already modified differently in target) → SPDD (dictionary objects) / SPAU (other objects) → manual adjustment required --- ## 2.
