rfmcall v1.3.1

rfmcall

ABAP RFM calls from NodeJS even easier.

RFM call templates, with pre-initialized ABAP data structures, saving the development and troubleshooting time: rfmcall @ SAP SCN

Maintained as a part of SAP Fundamental Library for ABAP, can be used also independent.

Usage

Invoke the utility with ABAP backend destination (maintained in sapnwrfc.ini) and ABAP RFM name. The RFM call template is by default echoed to console, with the source code for RFM parameters initialization and invocation.

$ npm install rfmcall

$ rfmcall MME STFC_CONNECTION
//
// STFC_CONNECTION
//

let params = {

  // IMPORT PARAMETERS

  REQUTEXT                         :   "", // CHAR (255)
};

result = await client.call("STFC_CONNECTION", params);

Using the -s option, the template is saved to local js file:

$ rfmcall MME BAPI_USER_GET_DETAIL -s

$ cat BAPI_USER_GET_DETAIL.js

RFM Template

The RFM call template starts with ABAP RFM parameters initialization, followed by RFM call.

• Optional parameters are commented out
• RFM elementary parameters (variables) are initialized with a NodeJS number, string of Buffer
• RFM structure and table parameters are initialized with empty object {} or array []
• The structure name is provided in a comment, with the detailed field level initialization following below
• The name of conversion (ALPHA) exit, if relevant for certain parameter or field, is provided in a comment (see BAPICOMREM/LANGU below )

BAPI_USER_GET_DETAIL.js

//
// BAPI_USER_GET_DETAIL
//

let params = {
  // IMPORT PARAMETERS

  USERNAME: "", // CHAR (12) User Name
  //CACHE_RESULTS                  :   "", // CHAR (1) Temporarily buffer results in work process

  // TABLE PARAMETERS

  RETURN: [], // BAPIRET2 Return Structure

};

// ADDCOMREM BAPICOMREM BAPI Structure Communication Comments

let ADDCOMREM                         =   []; // BAPICOMREM BAPI Structure Communication Comments

let BAPICOMREM = {
  COMM_NOTES                       :   "", // CHAR (50) Communication link notes
  COMM_TYPE                        :   "", // CHAR (3) Communication Method (Key) (Business Address Services)
  CONSNUMBER                       :   "", // NUMC (3) Sequence Number
