Update Mechanism in SAP

Update Mechanism:

·         Go to SM14

·         And ensure that update is active

·         If it is deactivated

·         Go to System logs (SM21) and ABAP dumps (ST22) and

·         Analyze the reasons.

Update will be only deactivated during inconsistency, if the parameter rdisp/vb_stop_active.

à Configuring updates:     use parameter rdisp/wp_no_vb configuring V1 updates.

                                           Use parameter rdisp/wp_no_vb2 configuring V2 updates.

à Update reorganization:

1. Define the parameter:

            rdisp/vbdelete to delete the update requests which are older than specified age,

                irrespective of status.

2. Use report RSM13002 to delete the old update requests which are executed on the database.

3. rdisp/vbmail: This is used to notify the Administrator if update error occur.

Parameter set =1 mail is sent

Parameter set =0 no mail is set

Note: The update is thrown into error and the error is resolved but the update is still with the status error. Select the update request and respect update (click on)

Note: It is also possible that update will be thrown in to error and could not update the database. In this scenario we may need to recreate the transaction again, i.e. when the system is terminated abnormally the update request may be lost in the transit. In this scenario the end users are required to recreate transaction again
