Global Data of View Cluster MaintenanceLocate this document in the navigation structure

Procedure

The central part of the view cluster maintenance is realized in function group SVCM. All data relevant during the maintenance are contained in the variables and internal tables of this function group.

Since specific events for an application cannot be implemented in this function group, access to this data must also be made possible outside of the function group. The ABAP concept of the COMMON area is used. All global data of the view cluster maintenance (which also has to be accessible in events), is declared in a COMMON area of the Include LSVCMCOD. This include must be included in the program that contains the events of the view cluster maintenance. Note that these program of the events is not a functiong group as function groups cannot access common data using common areas.

If you have to access data of the view cluster maintenance in an event of the view maintenance, the program code must be stored in a routine in this program which is then to be called as an external perform from the event of the view maintenance.

The global data is differentiated in the following ways:

  • Global data which can be accessed directly

  • Maintenance and data tables for each object which can be accessed using the form routine VCL_SET_TABLE_ACCESS_FOR_OBJ.
