Simple Transformations

Simple Transformations (ST) is an SAP programming language for describing transformations between ABAP data and XML formats. ST is restricted to the two modes of serialization (ABAP to XML) and deserialization (XML to ABAP) of ABAP data, which are most important for data integration. Transformations from ABAP to ABAP and XML to XML (like in the more general XSLT) are not possible in ST.

Simple transformations are created as ST programs. ST programs can be edited using the Transformation Editor. This is called up either with transaction STRANS or by choosing Edit Object → More → Transformation followed by Simple Transformation in the ABAP Workbench object navigator Existing ST programs can be called using the statement CALL TRANSFORMATION. The associated ST processor is integrated into the ABAP runtime environment.

In comparison with XSLT, the main advantages of ST programs are as follows:
