4 Eye Control in the Maintenance of Static Data

If the dual control principle is activated. when modifying the static data system, the data are not written directly into the static data table. A pending item (SPT) with a special status is created instead and is waiting for releasing. This pending item contains additional relevant release information.

When selecting a static data record it is checked, whether there exists a pending item for the desired object. If so, a correspondent message is displayed and the record cannot be modified.

The new releasing transaction “Releasing Pending Items” (SPTREL) allows a selective access to the various modifications and ensures, that the modifying user and the releasing user do not have the same user ID. A display file (DSP file) of the entry panel can be called, in which the modified fields are marked. Thus, the releasing user can retrace, what data have been modified. Additionally, the info system can be called for the according record, in order to display its history.

Within the releasing process the controlling user can either release the modification or send it back for Repair, or he can reject the modification.

If the item was released, the final processing of the modification is done via “Manager for Automatic Execution of Pending Items” (SPTTSK). The record can be edited again when the processing has been completed successfully.

As a side effect, static data modifications can be interrupted via . When taking up an interrupted item it is checked whether the original data has been changed. If so, the user will be notified accordingly.

As a basic principle, dual control can be enabled for any static data table individually.

This function is also available for system parameters as well as for calendars and timezones; in this case, instead of a database table, the files are handled in line with the profile data and the configuration files, respectively.

In the developer documentation you will find details on implementation along with information on the concept and technical implementation of the 4 Eye Control principle under “4 Eye Control - Technical Aspects”.
