# SAP Analytics Cloud Scripting

Comprehensive skill for scripting in SAP Analytics Cloud (SAC) Analytics Designer and Optimized Story Experience.

## Plugin Components

This plugin provides specialized tools for SAC development:

**Agents** (use via Task tool):
- `sac-script-debugger` - Debug script errors, trace issues
- `sac-performance-optimizer` - Analyze and fix performance bottlenecks
- `sac-planning-assistant` - Guide planning operations and version management
- `sac-api-helper` - Find correct APIs and provide code examples

**Commands** (use via /command):
- `/sac-script-template` - Generate script templates (filter, planning, export, etc.)
- `/sac-debug` - Interactive debugging guidance
- `/sac-optimize` - Performance analysis and recommendations
- `/sac-planning` - Planning operation templates

**Hooks**:
- Automatic validation on SAC script writes for common issues

## What's New in Q4 2025 (2025.21)

Key scripting enhancements in the latest SAC release:
- **Chart Variance APIs** - Script control over chart variance display
- **Compass for Seamless Planning** - Enhanced planning integration
- **Data Actions Enhancements** - Automatic dimension mapping, input control binding
- **Time Series Forecast API** - Programmatic forecasting control
- **Comments APIs** - Widget and cell comment management

See `references/whats-new-q4-2025.md` for complete details.

## Quick Start

### Script Editor Access
- **Analytics Designer**: Edit mode → Select widget → Scripts tab
- **Optimized Story Experience**: Advanced Mode → Select widget → Add script

### Basic Script Structure
```javascript
// Event handler example (onSelect on Chart_1)
var selections = Chart_1.getSelections();
if (selections.length > 0) {
    var selectedValue = selections[0]["Location"];
    Table_1.getDataSource().setDimensionFilter("Location", selectedValue);
}
```

## Core APIs

### DataSource API
Access via `Widget.getDataSource()`. Key methods:
- `getMembers(dim, {accessMode: MemberAccessMode.BookedValues})` - Get dimension members efficiently
- `getResultSet()` - Cached data access (preferred over getData())
- `setDimensionFilter(dim, value)` - Apply filters
- `setRefreshPaused(true/false)` - Batch multiple operations

### Planning API
Access via `Table.getPlanning()`. Key operations:
- `getPublicVersion()` / `getPrivateVersion()` - Version access
- `publish()` - Submit private to public
- `copyFromPublicVersion()` / `copyToPublicVersion()` - Data copy
- `setLock(true/false)` - Data locking

### Widget APIs
- **Charts**: `addMeasure()`, `addDimension()`, `getSelections()`
- **Tables**: `addDimensionToRows()`, `setZeroSuppressionEnabled()`
- **Containers**: Panel, TabStrip, PageBook for layout

### Application Object
Global utilities:
- `Application.showBusyIndicator()` / `hideBusyIndicator()`
- `Application.showMessage(type, text)`
- `Application.getUserInfo()` / `getInfo()`

## Performance Best Practices

1. **Minimize Backend Calls**
   ```javascript
   // Use getResultSet() (cached) instead of getMembers() (backend)
   var data = ds.getResultSet();
   ```

2. **Batch Filter Operations**
   ```javascript
   ds.setRefreshPaused(true);
   ds.setDimensionFilter("Dim1", value1);
   ds.setDimensionFilter("Dim2", value2);
   ds.setRefreshPaused(false); // Single refresh
   ```

3. **Keep onInitialization Empty**
   Defer heavy operations to lazy loading or first interaction.

4. **Use BookedValues for Members**
   ```javascript
   var members = ds.getMembers("Dim", {accessMode: MemberAccessMode.BookedValues});
   ```

## Debugging

### Console Logging
```javascript
console.log("Debug:", myVariable);
console.log("Selections:", JSON.stringify(Chart_1.getSelections()));
```

### Browser DevTools
1. Press F12 → Console tab
2. Filter by "Info" type
3. Add `?APP_PERFORMANCE_LOGGING=true` to URL for timing
