Hi,

You must write a RFC enabled Functional Module which will generate the document or whatever you want. Now using JCo you will be able to perfrom the same from an external application. Refer to the JCo document that comes with the JCo jar. It will be very much helpful.

Thanks & Regards,

Hi ganesh,

Looking at ur latest q, JCo is just an interface to connect SAP backend with your Appl program.That all.

if you want to generate doc no you have write BAPI/RFC in ABAP and probably call them using JCo.

Check this link for Bapi documentation

Hello ganesh,

The standard way of communication b/w SAP & Java is done thro JCA(Java Connector Architecture).Ons such interface(very common) in JCA is JCo.Using JCo you can connect your sap R/3 backend with your appl programming either Java or Webdynpro.

For using JCO you shd configure it.You have create your SLD & Modeldata & metadata.

Refer thsi for the same.

Hi Ganeshan,

Welcome to SDN.

SAP Java Connector can help you get this done. Besides you must have some idea about SAP Remote Function Calls using which you can access SAP Repository.

You can download that from SAP Service Market Place.

Hello Gajju,

up to my knowledge the only interface between java and SAP is the Java Connector (JCo). With the JCo-API you can handle connections to any SAP-system and call (remote) function modules which will do the stuff you need.

With best regards,
