If you want to delete old shortdumps from your SAP system then you can use the following ways to do this.Importing point is ; before you delete them, you must analyze the cause of the short dump using transaction code ST22.

Let’s check these ways on an example situation like below ;

To delete these entries  , first option is using the ABAP program RSSNAPDL

Go to SE38 and execute the program as shown below

Change the values of the program for your own condition and EXECUTE

Second option to delete these entries , just open ST22 and run “Reorganize” option

ST22 –> Goto –> Reorganize

Change the value of “Older than …” and click the Reorganize button

Third option is dropping the related SNAP table , goto  SE14 –> drop and recreate the SNAP table.
Don’t forget that , when you are doing this all short dumps are deleted.
