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:
ST> programs are declarative and thus easier to read.
ST> programs only have serial access to the XML> data and are therefore very efficient even with large data volumes. The nodes in XML> data, however, cannot be accessed in an arbitrary order.
ST> programs describe serialization and deserialization simultaneously, that is ABAP data serialized in XML> with ST > can also be deserialized with the same ST> program.
Objects can be created from ABAP Objects and their methods called in ST> programs.
ST> programs are restricted to the transformation of elementary and structured ABAP data, along with internal tables. The transformation of reference variables and referenced objects is not currently supported.
