Automatically Reorganizing Short Dumps
A short dump is saved in the database table SNAP in the error log for every runtime error that occurs in an ABAP system. Unless they are intended for retention and marked accordingly, these long texts are automatically released for deletion four weeks after they are generated.
Old short dumps are deleted successively: If a program that is running in a window of the SAP GUI terminates with a runtime error and the short dump is displayed directly, then older short dumps are searched and deleted (maximum 100 for performance reasons). The number of short texts not intended for retention in an ABAP system is therefore regularly regulated.
Stopping Short Dumps from Being Automatically Deleted
You can prevent short dumps from being automatically deleted:
For this purpose, start the ABAP Dump Analysis (ST22).
Select the corresponding short dump.
Choosefrom the menu.
The short dump is then stored in the database until you revoke the lock using the same function.
For more information, see SAP Note 11838 "Deleting Short Dumps from the SNAP Table".
Manually Reorganizing Short Dumps
This mechanism does not apply, however, if a runtime error occurs during background processing, an RFC call (including JCo), or an HTTP call. It is therefore also possible to selectively delete short texts from the database manually. To do this, on the initial screen of the transaction ABAP Dump Analysis (ST22), choose the Reorganize option from the Goto menu.
A selection screen appears, on which you can define the age as of which the short texts are to be deleted.
Note that this function is only available in the cross-client variant of the ABAP Dump Analysis. See Authorization Checks
Reorganization as Automatically-Scheduled Operation (by the System Administrator)
If you need to regularly perform reorganization operations in a system and want to automate this step, you can schedule the program RSSNAPDL. This program provides the same function as the menu option Reorganize.
You can view the current size of table SNAP at any time by choosing the SNAP Statistics option from the Goto menu.
