# sap-abap

A skill that guides an agent through ABAP code: internal tables, ABAP SQL, RAP, CDS, EML, unit tests. Useful when the project runs on SAP and the syntax has to match a specific release.

## What it does

The skill covers how ABAP is written: data declarations, constructor operators such as VALUE, NEW and CONV, table expressions, string templates, exception handling, dynamic programming, RTTI/RTTC, field symbols and data references. Modern ABAP for Cloud Development gets its own treatment — RAP, CDS views, EML statements.

A compatibility table maps features to releases, from 7.40 SP08 up to ABAP Cloud. Anything that needs a newer release carries an inline marker like `" [7.xx+]` in the examples. On a 7.40 system you swap `FINAL(...)` for `DATA(...)` and skip the 7.50+ features. Most of the modern syntax — VALUE, NEW, CONV, inline declarations, table expressions, REDUCE, FILTER, `GROUP BY` — works from 7.40 SP08 onward.

There is also an error catalog, performance notes and a list of source documentation. Related skills sit alongside it: `sap-abap-cds`, `sap-btp-cloud-platform`, `sap-cap-capire`, `sap-fiori-tools`, `sap-api-style`. If several of them are installed, watch that the agent does not blend advice meant for different layers.

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add secondsky/sap-skills --skill sap-abap -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/sap-abap/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/sap-abap/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add secondsky/sap-skills --skill sap-abap -a cursor
```

2. **Manually: put the files in place**

gemini skills install https://github.com/secondsky/sap-skills --path plugins/sap-abap/skills/sap-abap
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/sap-abap/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

## When to use it
- write ABAP that matches the release of the target system
- move classic ABAP toward ABAP Cloud patterns
- build an ABAP SQL query with joins and aggregates
- work through internal tables and field symbols
- add ABAP unit tests to existing code

## Example prompts
- Declare an internal table with a key and fill it using VALUE
- Rewrite this SELECT as ABAP SQL with host variables and check it works on 7.40 SP08
- Show me how to do this with RAP and a CDS view
