SAP connectivity from Java to SAP 4.0

[#1]

Hi All,

I am tried to send an IDOC(whose basic type, extension are known) to SAP system(ECC 6.0) using the SAP JCo API 3.0 and all works well.

Now I used the same piece of code to connect to SAP 4.0 system but the following basic line of code has ran into a IDOCRUNTIMEEXCEPTIION

doc = iDocFactory.createIDocDocument(iDocRepository, iDocType, iDocCymType);

com.sap.conn.idoc.IDocRuntimeException: Unable to get metadata for MATMAS03 with extension YES2P_IEXT_MATMAS03: Function module "IDOCTYPE_READ_COMPLETE" not found.

Now my question is how do I create an IDOC(a blank one) using this API for 4.0 system which doesnt seem to have this function module OR does anyone know other method create IDOC using SAP JCo3.

Please comment. Thanks in advance

We are also still looking for an answer for this issue. The server in our case is running SAP 4.0 package 17 and the function (IDOCTYPE_COMPLETE_READ) only gets added in package 42. However the JCo connector page states it supports R/3 3.1 and newer, so is this a bug or is there an alternative function we could use?

This space is specifically for the Java SDK for BusinessObjects.  I'm not sure which space is appropriate for your question, but you probably won't get any answers here.  Sorry!
