Description

This example passes various types of numeric ABAP data including the time stamp to the transformation DEMO_ST_DECIMALS_OPTION and provides the result for XML and JSON. The transformation applies the option decimals to the ABAP data:

The transformation creates JSON-XML to represent both XML and JSON. The time stamp in packed number datetimel is typed with the special domain XSDDATETIME_LONG_Z. This time stamp is still handled as such after the handling by decimals. For the number timestmpl of type p, the corresponding effect is obtained by using the additional time stamp formats specified with format. Time stamps in time stamp fields of the type utclong are handled as such by default.
