Formal verification of ABAP by Z specification

Abstract

This paper has proposed a formal verification of ABAP by Z specification. An ABAP programming language is used to create a customized program in SAP ERP. The program must satisfy a business requirement. It likely has a defect from the developed program. Since a specification is created as the business requirement and a program should have functioned as in the specification, the formal verification is needed to assure the correctness of the function in the program. Both an ABAP program and its specification are translated into Z specification and they are verified by Isabelle in order to ensure that the ABAP program conforms to its specification. We also give some experimental result to show the effectiveness of our method.
