This sample shows to create a sales order in the SAP system using the IDoc type ORDERS01.

About #

An IDoc to create sales orders requires three different kinds of segment types:

  • E1EDK01 is the main segment of an ORDERS01 IDoc. We leave it empty, but it must be provided by the calling program to pass the SAP IDoc syntax check.
  • E1EDP01 is the segment for a single order position. The field MENGE contains the quantity. This segment can occur more than once.
  • E1EDP19 represents an object definition and is a child of E1EDP01. In this case the object is a material number. The field QUALF is therefore set to “002” and the material number is written into the IDTNR field.

Tip: Use SAP transaction WE60 to look up the segment documentation of IDoc type ORDERS01.

Prerequisites #

Set up an RFC destination to enable calls from an SAP system to a subsystem, see Online Help: IDocs Prerequisites.
If there is no partner profile found for an incoming IDoc, no order will be created.

The Windows form for the sales order contains the following elements:

  • Two text boxes for input: txtMaterialNumber (material number) and txtQty (quantity).
  • One button: button1
private void button1_Click(object sender, System.EventArgs e)
 // Set your ERPConnect license

 using var connection = new R3Connection(
    host: "",
    systemNumber: 00,
    userName: "user",
    password: "passwd",
    language: "EN",
    client: "001")
    Protocol = ClientProtocol.NWRFC,

 Idoc idoc = connection.CreateEmptyIdoc("ORDERS01","");
 idoc.MESTYP = "ORDERS";
 // Fill information about idoc sender
 idoc.SNDPRN = "1172"; // Partner number
 idoc.SNDPRT = "KU"; // Partner type
 // Create document header segment
 IdocSegment e1edk01 = idoc.CreateSegment("E1EDK01");
 // Create item segment
 IdocSegment e1edp01 = idoc.CreateSegment("E1EDP01");
 e1edp01.Fields["MENGE"].FieldValue = txtQty.Text;
 // Create Object identification (material number in this case)
 IdocSegment e1edp19 = idoc.CreateSegment("E1EDP19");
 e1edp19.Fields["QUALF"].FieldValue = "002"; // 002 for material number
 e1edp19.Fields["IDTNR"].FieldValue = txtMaterialNumber.Text; // material number
 this.lblInfo.Text = "Idoc sent";
