MIC_FOPCS_SHM_CUST - Activate Shared Objects Memory

General Data in Customer Master   General Material Data  
This documentation is copyright by SAP AG.

In this IMG activity, you can activate the use of the Shared Objects Memory for the following data:

• Central Organizational Hierarchy

• Central Account Group Hierarchy

• Central Management Control Catalog

• Central Process Catalog

• Processes of the Organizational Unit

It is not possible to use the Shared Objects Memory for all other objects transferred from organizational units (such as account groups or management controls).

Using the Shared Objects Memory improves system performance when calling up data in the corresponding Web applications. When the Shared Objects Memory is activated for the organizational hierarchy, for example, and a user calls up the organizational hierarchy, the system creates a buffer for the organizational hierarchy in the relevant timeframe and loads the data into the buffer. When another user then calls up the organizational hierarchy in the same timeframe, the data is loaded from the buffer, not from the database. However, if the personalized timeframe of the user does not agree exactly with the timeframe of the buffer, then, instead of accessing the buffer, the user accesses the database directly.

When the Shared Objects Memory is activated for the central structures and catalogs, the system creates a separate area instance for each timeframe. When the Shared Objects Memory is activated for the processes transferred from an organizational unit, the system creates a separate area instance for each organizational unit and timeframe.

To guarantee that performance is actually improved, you should only activate the Shared Objects Memory if users generally call up the data with read-only access.

Structure setup is complete so that users only call the data using read-only access (such as for assessments and tests).

1. Activate the Shared Objects Memory (if needed) by entering each object type and timeframe for which you want to use the memory.
2. You deactivate the Shared Objects Memory by deleting the given entry for the object type and timeframe. Doing so invalidates all existing area instance versions.
3. In the IMG activity Monitor Active Areas (transaction SHMM), you can monitor which area instances exist in the system.

For more information about Shared Objects Memories, see Help -> Application Help in transaction SHMM.

You activate the Shared Objects Memory for the processes transferred from the organizational units and specify the timeframe Year 2006.

Users with the personalized timeframes below access the data as follows:

• Year 2006 -> Shared Objects Memory

• 2nd Quarter 2006 -> Database
