we are on SAP MySAP ERP 2004 (ECC 5.0 - NW2004 ) , with only ABAP stack activated, no JAVA stack yet. No UNICODE active , code page Latin 1; DIMP active
If we want e.g. use the Employee Self Services , we have to activate the Java Stack.
I heard from another customer that UNICODE is pre-requisite for JAVA ; Is this correct ? Where can I find documentation on this ?
We looked into OSS, PAM, Java SAP Installation Guide, but don't find prerequisites in that direction. Only some notes about MDMP, but that we don't use.
The Java stack is always unicode, but still it is possible to add the java (unicode) add-in to a non-unicode ABAP stack.
Anyway, keep in mind that full integration between ABAP and JAVA components can be achieved only with Unicode Systems, as JAVA is based on Unicode. In non-Unicode systems there is always danger of data loss during text data transfer from the J2EE part to the ABAP part.
