Prerequisites

  • SAP NetWeaver 7.52 or higher (developed and tested on this release)
  • /UI2/CL_JSON PL12 or higher recommended

Installation

  1. Install via abapGit
  2. Optionally abap-to-json if /UI2/CL_JSON is outdated. See Badi_ZLLM_IMPLEMENTATION.md for details on required further steps if you use the abap-to-json implementation.

Configuration

  1. Setup TLS 1.2 properly as described for abapGit
  2. Create RFC destinations for the providers see Provider Documentation for details
    • Ollama path prefix /api
    • OpenAI path prefix /v1
    • Openrouter path prefix /api/v1
    • AzureOpenAI path prefix /openai/deployments
    • Anthropic path prefix /v1
  3. Add required SSL certificates in STRUST for the providers you want to use
  4. Configure the provider via report ZLLM_PROVIDER_MAINTENANCE

For details on the model configuration see Client Configuration.

Encryption Setup

Authorization values in the provider configuration are encrypted via SSF. Mandatory setup:

  • SE16 Table SSFAPPLIC create a new entry:
    • APPLIC: ZLLMCT (this name is mandatory, otherwise you need to update the code)
    • All B_XXX fields set as 'X'
    • Descript: LLM Client Credentials (you can use any description)
  • Transaction SSFA create a new entry for the application created above:
    • Hash Algorithm: SHA256
    • Encryption Algorithm: AES256-CBC
    • Keep all others as default
  • Transaction STRUST
    • Right click on the new entry named as you defined above and select create, use default settings
    • Hint: this is usually the last entry in the list

Note that the application name is currently hardcoded, if you require a different value edit class zcl_llm_encryption. You might also open an issue to request this to be a configurable setting based on demand I might consider this, however as this is a quite rare setting in an ABAP system I do not expect any collisions with existing custom values.
