SAP 4.0 B support SAP Java connector??

Former Member

We are having a java application which we have developed using SAP Java connectors using JCo programming.

The same application is working fine with SAP ECC 6.0.

Now one of our client is asking for the support of the same application on the SAP 4.0 B which is very old version of SAP ERP.

As our application is based on SAP Java connectors and developed using using SAP JCo 2.1 and SAP JCo 3.0, and the same is working fine withbSAP ECC 6.0.

Can anyone tell me :-

a) SAP 4.0 B supports SAP Java Connctors(SAP JCo 2.1 or SAP JCo 3.0)

b) If SAP 4.0 B supports SAP Java Connectors then the same JCo programming based Java application which is working fine with SAP ECC 6.0 will      

   work with SAP 4.0B or not.

Hello Tanvi,

it's the other way round: JCo 2.1 and JCo 3.0 both support the commuication with a 4.0B ABAP system. And yes, a program developped for for 4.0B works as well with ECC 6. The assumption there is that in case custom ABAP development was involved, the same custom modules are part of the ECC 6 system. Furthermore, zou only used released function modules declared as API that may not change incomatibly. In addition, you might need to adjust some security settings compared to 4.0 when setting up the communication. Oh, just saw you asked the other way round.

Then there are some more things to consider. In case you used nested datatypes, DECFLOAT, STRING datatypes, tables in importing exporting, and some more things, it will not work with 4.0B. Those datatypes are either not existing in 4.0B or cannot be used like that in that release. Actually, you need to ensure that the function module is restricted to features already avaiable in 4.0B.

Best regards,

Markus

Thanks Markus.

We have not hard coded any data type,Import Parameters,Table Parameters and Function Modules.

We are fetching Function Template while running our Application using SAP JCo libraries 2.1 or 3.0.

Right Now we are testing it in actual with the SAP 4.0 B by deploying our application on the client machine and will update the status of the same very soon.
