## Overview

SAP Business Application Studio is a cloud-based IDE on SAP BTP built on Code-OSS (VS Code foundation). It provides tailored dev spaces for SAP Fiori, CAP, HANA, and mobile development with pre-installed tools and runtimes.

**Architecture**: Multi-cloud SaaS (AWS, Azure, GCP) with isolated dev spaces functioning as Developer Virtual Appliances.

## Setup Checklist

### Prerequisites
- SAP BTP global account
- Subaccount in Cloud Foundry environment

### Steps

1. **Create Subaccount** - Select region based on [availability](https://help.sap.com/docs/bas/sap-business-application-studio/sap-business-application-studio-availability)
2. **Configure Entitlements** - Add SAP Business Application Studio service plan
3. **Subscribe** - Complete subscription in subaccount
4. **Assign Roles** - Add `Business_Application_Studio_Developer` role collection
5. **Optional: Configure IdP** - Set up assertion-based attribute mapping
6. **Optional: Connect Git** - Link to public or corporate repositories
7. **Optional: Create CF Spaces** - At least 1 space per development team

For detailed setup: See `references/setup-checklist.md`

## Service Plans

| Plan | Dev Spaces | Running | Storage | Notes |
|------|------------|---------|---------|-------|
| **Standard** | 10 | 2 | 10 GB | Production development |
| **Free** | 2 | 1 | 4 GB | Community support only, 2 deployments max |
| **Trial** | 2 | 1 | 4 GB | 1-hour timeout, 30-day inactivity deletion |
| **Build-Code** | Varies | Varies | Varies | Requires SAP Build Code subscription |

For restrictions: See `references/service-plans.md`

---

## Connectivity

### Required Destination Properties

```
WebIDEEnabled = true
HTML5.DynamicDestination = true
```

### WebIDEUsage by System Type

| System Type | WebIDEUsage Value |
|-------------|-------------------|
| ABAP System | `odata_abap,dev_abap` |
| SAP Cloud for Customer | `odata_c4c` |
| Service URL | `odata_gen` |
| SAP Business Accelerator Hub | `apihub_sandbox` |

### Cloud Connector Requirements (On-Premise)

1. Virtual URL in Cloud Connector must match destination URL (host:port only)
2. Protocol must be HTTP
3. Grant access to required paths:
   - `/sap/opu/odata/` (OData services)
   - `/sap/bc/ui5_ui5/` (UI5 resources)
   - `/sap/bc/adt/` (ABAP Development Tools)
   - `/sap/bc/ui2/app_index/` (App index)

For troubleshooting: See `references/connectivity-guide.md`

---

## Build & Deploy

### Prerequisites

1. Log into Cloud Foundry account
2. For HANA apps: Add "SAP HANA Cloud, SAP HANA Schemas & HDI Containers" entitlement
3. For Trial/Free: Add "SAP Build Work Zone, standard edition" + Launchpad_Admin role

### MTA Deployment

```bash
# Build MTA archive
mbt build

# Deploy to Cloud Foundry
cf deploy mta_archives/<app>.mtar
```

### Key Tools

- **MTA Editor**: Visual editing of `mta.yaml`
- **Cloud Foundry CLI**: `cf` commands for deployment
- **Cloud MTA Build Tool**: Generates `.mtar` files
- **Task Explorer**: Execute build/deploy tasks

---

## Roles & Authorization

| Role | Purpose |
|------|---------|
| **Developer** | `Business_Application_Studio_Developer` - Application development |
| **Administrator** | Export/delete user data, restart dev spaces |
| **Extension Deployer** | Create and deploy custom extensions |

Assign via: SAP BTP Cockpit → Security → Role Collections

---

## Common Issues

### Dev Space Stuck in STARTING
1. Wait 5 minutes
2. If persists, start new dev space and restore via Git
3. Contact support with workspace ID (ws-id)

### Connectivity Failures
1. Verify destination in BTP Cockpit (WebIDEEnabled, HTML5.DynamicDestination)
2. Check Cloud Connector configuration
3. Run in terminal: `curl localhost:8887/reload` then `curl $H2O_URL/api/listDestinations -o dests.json`

### Storage/Inode Issues
```bash
df -ih  # Check inodes
df -h   # Check disk space
```
Remove cache folders and unnecessary files.

### HANA Connection Issues
Configure SAP HANA Cloud to allow BAS IP addresses. See [Availability](https://help.sap.com/docs/bas/sap-business-application-studio/sap-business-application-studio-availability) for region IPs.

## Keyboard Shortcuts

| Action | Shortcut |
|--------|----------|
| Command Palette | `F1` or `Cmd+Shift+P` |
| Select parent control | `Ctrl+Click` |
| Move control up | `Shift+Left Arrow` |
| Move control down | `Shift+Right Arrow` |

## Security Recommendations

- **BTP-BAS-0001**: Limit administrators with full management permissions
- Use Personal Access Tokens (PATs) for Git authentication
- Protect connections to external systems
- Avoid personal data in source files when using Joule AI
