Shared Objects to Release 7.0

1. Data references in the Shared Objects Memory

Other versions: 7.31 | 7.40 | 7.54

Modification 1

Data references in the Shared Objects Memory

Since Release 7.0, data references that point to data objects of the same area instance version, can be stored permanently in the Shared Objects Memory. An instance of a shared memory enabled class can contain data reference variables as attributes that point to data objects within a closed area instance version. An exception only occurs if the used data type is unknown to the DETACH_COMMITmethod in the Shared Objects Memory during execution. This is the case if the types of the referenced data objects were created dynamically. Due to technical reasons, no direct reference to data elements and table types of the ABAP Dictionary is possible as well.

The opportunity to store data references in closed area instance versions makes it possible - since release 7.0 - to store not only instances of classes, but also anonymous data objects with the addition AREA HANDLE of the statement CREATE DATA as Shared Objects.

Waiting period for change locks

Since release 7.0, a waiting period can be transferred to the parameter WAIT_TIME for the methods ATTACH_FOR_WRITE and ATTACH_FOR_UPDATE of the area class. The same applies for MULTI_ATTACH of CL_SHM_AREA.
