Mapping / OSIS Application Modules

The third OSIS-Layer, the level for mapping, contains modules for converting, and translating the data.
Here are some examples of the application orientated OSIS modules:

• Conversion between various format structures and field formats. Complex calculations, calculation of control digits, (z. B. EAN-control digit), conversion of dates.
• Sorting of data using the content of predetermined fields as a reference.
• Translation and conditional translation, here messages are edited according to their content, translation tables and sometimes requiring research in an SQL database table.
• Logical checks for the data consistence using pre-defined rules.
• Branching / duplication of data in a message using conditions that determine the transmission procedure thus determining which follow on processing, via other application modules, is carried out.
• Archiving of data with the option that the continuation of the processing can be event triggered or scheduled.
• Distribution, routing of data groups to various partners. The address information (i.e. communication partner, communication protocol and other parameters for the send process) can be specified in a static table or dynamically generated from the data during processing.
• Combining and re-routing of data from various files.
• Merging of files / messages of the same kind into one file, carried out according to the predetermined merging criteria.

The diagram shows a message/file workflow through the various OSIS levels and modules. The message type ORDERS, transferred from an SAP R/3 system in the IDOC format, is transmitted on one side to the supplier and on the other side to the warehouse´s SQL application database.
