I am going to transfer this topic to other certifications -- here is my convoluted reasons why... Since this is a Java site, it is likely that every forum should have some concept of Java, but not SAP. Any relationship between a SAP cert and a Java cert may be known by someone taking a SAP cert -- assuming there is a relationship.
The ABAP/SAP certification is not related to any JAVA certification.
Their targets are completly different.
I recommend you to take the scjp certitication. As for the ABAP/SAP certification i dont recommnend it, that's too theorical and expensive (500 $). Besides you dont get any skills, it' s just you need to cram and memorize a lot.
