node-r3trans

node-r3trans

Node.js wrapper for SAP R3Trans.

Installation

• Download the R3Trans program from SAP Software Download Center
• Create a directory and extract its content
• Create a new PATH enviroment variable named R3TRANS_HOME, pointing at the directory that was created earlier
• Install node-r3trans

npm install node-r3trans

Getting started

Start by importing the library and instantiating an object. If your transport is in a folder, you can pass the path as a string, like this:

const R3Trans = require('node-r3trans');
const transport = new R3Trans('C:\\R3Trans\\R904009.RST');

If your transport is a buffer:

const R3Trans = require('node-r3trans');
const trBuffer = fs.readFileSync('C:\\R3Trans\\R904009.RST');
const transport = new R3Trans(trBuffer);

Optionally, you can also pass an object containing these values:

const R3Trans = require('node-r3trans');
const transport = new R3Trans('C:\\R3Trans\\R904009.RST', {
    r3transHome: 'C:\\R3Trans' //Folder where R3Trans is placed, defaults to enviroment variable R3TRANS_HOME
    tmpFolderPath: 'C:\\R3Trans' //Folder where all temporary files are generated before being deleted, defaults to r3trans home. must have write access
});

Examples

Validate transport request

const R3Trans = require('node-r3trans');
const transport = new R3Trans('C:\\R3Trans\\R904009.RST');
transport.isValid().then(valid => {
    if(valid){
        console.log('OK');
    }else{
        console.log('NOT VALID');
    }
}).catch(e => {
    console.error(e);
});

List objects of a transport request

const R3Trans = require('node-r3trans');
const transport = new R3Trans('C:\\R3Trans\\R904009.RST');
transport.getTableEntries('TADIR').then(objects => {
    console.log(JSON.stringify(objects.map(o => `${o.R3TR} ${o.OBJECT} ${o.OBJ_NAME}`)));
}).catch(e => {
    console.error(e);
});

List all table entries of a transport request

const R3Trans = require('node-r3trans');
const transport = new R3Trans('C:\\R3Trans\\R904009.RST');
transport.getTableEntries().then(objects => {
    console.log(JSON.stringify(objects.map(o => `${o.R3TR} ${o.OBJECT} ${o.OBJ_NAME}`)));
}).catch(e => {
    console.error(e);
});
