Hammer

A native macOS code editor for ABAP and CDS, with an Object Navigator, Transport Organizer, Data Browser and Gateway Client in the same app as the editor.

Hammer edits ABAP and CDS objects in a connected SAP system from a native macOS IDE, with an Object Navigator, Transport Organizer, Data Browser and Gateway Client. It can use ADT; Hammer Core Services installation adds lock handling, SICF service control and abapGit integration on supported releases. Its integrated AI agent can update source and activation state in open tabs, with separate per-system access modes and approval settings.

Editor supportABAPEditor supportcapabilityWorking in source code with the editor helping rather than treating it as text — completion, go-to-definition, inline errors, refactoring and preview.Browsing table dataABAPBrowsing table datacapabilityLooking at what a system holds while developing or supporting it: the rows behind a key, the reference data a field points at, the tables that carry data for one object. Editing configuration records through maintenance screens is a different job, even where the same transaction does both.Change promotionABAPChange promotioncapabilityMoving a change through the environments of a landscape, from development through test to production, and knowing which change has reached which environment. A [CI/CD pipeline](capability:ci-cd) builds and tests on each source change, [deployment](capability:deployment) puts a build onto its runtime, and getting source into git is [source control](capability:abap-source-control).Agent access to your codeABAPAgent access to your codecapabilityLetting a coding agent read the project or the system you actually have, reach its model, its objects and its checks, and act on it. In file-based environments that works out of the box; complex systems need dedicated access capabilities. Whatever the environment, the agent also needs project- and framework-specific context, so it understands the thing in front of it rather than guessing from what it remembers of its training data. The transport is incidental: an MCP server, a language server or a CLI answer the same question, and what differs between them is how much of the real thing the agent can see. Distinct from [MCP servers](capability:mcp-servers), which is a protocol adapter on your own running service, and from [agent guidance](capability:agent-guidance), which is knowledge handed over as files rather than read from the thing itself.

Before choosing this

Conditions

PracticalFunctional boundary

It runs on macOS only. Hammer Core Services, the part installed into the SAP system, needs that system on ABAP Platform 2023 or newer with SAP_BASIS 758 or newer, and installing it needs a user who can create development objects and run background jobs in that system.

PolicySAP API Policy 4.2026a§ 1.1, 1.2, 2.2.2from Agent access to your codeAn MCP server calls ADT or another SAP API of a running system for an agent.
  • § 1.1 Published APIs. Published APIs are made available for the documented purposes identified by SAP, including integration, extensions and data exchange.
  • § 1.2 Non-Published APIs. Customer and third-party applications must not access non-published APIs except where documentation permits it or SAP otherwise authorizes it.
  • § 2.2.2 AI call sequences and data extraction. Outside SAP-endorsed architectures, data services or expressly identified pathways, the policy prohibits specified agentic API use and systematic or large-scale extraction.

An agent that plans and executes ADT calls is the case section 2.2.2 names. Check that the endpoints are published for the intended use, and that the design runs within a pathway SAP identifies for it.
