Sending IDOCs to SAP using SSIS – MSSQL Integration Services

February 7, 2012 6 comments

Normally receiving and sending IDOCs can be easily done by using BizTalk Adapter for mySAP Business in BizTalk Server which is included in Microsoft BizTalk Adapter Pack 2.0. But what if I want to send an IDOC using SSIS and BizTalk is installed on a different server? Below are the steps on how you can do that.

Note: Since SSIS 2008 only supports <= .NET 3.5 all custom assemblies that will be called within it should be using this framework.

Prerequisites:

1. WCF LOB SDK Adapter (WCF-LOB-Adapter-SDK-2010-x86.exe) – Get it here. or in BizTalk DVD Installer under BizTalk Server\ASDK_X86

2. Microsoft BizTalk Adapter Pack 2.0 x86 – Get Evaluation version here. or in BizTalk DVD Installer under BizTalk Server\AdapterPack_x86

3. SAP Libraries x86 – this needs to be installed on C:\Windows\SysWOW64 folder. See section for SAP Adapter in this Microsoft Adapter Pack 2.0 install guide.

IDOC Library:

Next step is to create an IDOC WCF Client that you can call inside SSIS.

1. Open Visual Studio -> Create a new Project Library.

2. Right click the Project -> Click Add Adapter Service Reference.

3. Set the binding to sapBinding and set the configure a URI to:

sap://CLIENT={SAP Client ID};LANG=EN;@A/{Application Server Host}/{System Number}?ListenerGwServ={Gateway Service}&ListenerGwHost={Gateway Host}&ListenerProgramId={Program Id}&RfcSdkTrace=False&AbapDebug=False.  See this help for the configuration

4. Click Configure and set the credentials, then click Connect. Since we are sending IDOCS the contract type should be set to Client (Outbound operations).

5. In the Category, browse for the specific type of IDOC and version, when generating the schema you might encounter an error : “Error returned by RfcCallReceiveEx while calling RFC: IDOCTYPE_READ_COMPLETE..”, It means that you’re selecting an incorrect version of the IDOC, you should ask your SAP resource to identify the Release Number.

Select the Send and click Add. Click OK. This will generate a WCF client that you can call inside SSIS.

6. Sign the Assembly, compile and deploy to GAC then copy to C:\windows\Microsoft.NET\Framework\v2.0.50727.

It’s necessary to copy to this folder so you can add a reference to it in SSIS.

SSIS:

1. Add a data flow.

2. Set OLE DB Source / File / etc.

3. Add a Script Task, set the script task to Script Destination. Double click the script task and change the target framework to .NET 3.5 by going to project properties.

Add reference to the IDOC Library.

Create the IDOC object and pass it to the IDOC WCF Client.

                // confirm the transaction on the SAP system.

                // Get SAP tx id from GUID
                sapTxId = SAPAdapterUtilities.ConvertGuidToTid((Guid) adapterTxGuid);

                Console.WriteLine("IDOC sent");
