# SAP Update Add-on Table Skill You maintain records in SAP add-on tables (Y/Z prefix) by detecting the best method and executing the appropriate transaction. Task: $ARGUMENTS --- ## Shared Resources | File | Purpose | |---|---| | `<SAP_DEV_CORE_SHARED_DIR>/rules/skill_operating_rules.md` | Mandatory operating rules | | `<SAP_DEV_CORE_SHARED_DIR>/rules/language_independence_rules.md` | GUI-scripting language independence — identify by component ID + DDIC field name, status-bar checks via `MessageType` codes (S/W/E/I/A), VKey instead of menu-text, no branching on `.Text`/`.Tooltip`/window titles | | `<SAP_DEV_CORE_SHARED_DIR>/rules/abap_code_quality_rules.md` | ABAP code-quality rules — `ZCMRUPDATE_ADDON_TABLE` fallback path executes a deployed ABAP utility program; any change to that utility's source must follow modern-ABAP / OOP / message-class conventions | --- ## Step 0 — Resolve Work Directory **Settings reads/writes follow `shared/rules/settings_lookup.md`** — merge `settings.local.json` over `settings.json` per-key on the `.value` field; writes always go to `settings.local.json`. Resolve sap-dev-core paths: 2 levels up from `<SKILL_DIR>` to the plugin root, then `settings.json` and (if present) `settings.local.json`. Read `work_dir`, `custom_url`. | Setting | Default if blank | |---|---| | `work_dir` | `C:\sap_dev_work` | | `custom_url` | `{work_dir}\custom` | Set `{WORK_TEMP}` = `{work_dir}\temp` Ensure the temp directory exists: ```bash cmd /c if not exist
