call_rfc

Invoke a classic RFC function module on the SAP system via SOAP-over-HTTP (/sap/bc/soap/rfc). Use this for BAPIs, STFC_CONNECTION, custom RFC FMs, etc.

Defined in packages/adt-mcp/src/lib/tools/call-rfc.ts.

Input schema​

{
  baseUrl: string;   // SAP system base URL
  client?: string;   // SAP client number
  username?: string; // Username for basic auth
  password?: string; // Password for basic auth
  functionModule: string; // RFC function module name (case-insensitive, e.g. "STFC_CONNECTION")
  parameters?: Record<string, unknown>; // Flat key/value map of RFC parameters. Scalars as strings; structures as objects; tables as arrays of objects.
