The data supplier programs report data about the systems in your landscape to the SLD. If a system no longer exists in your landscape, the data about the system remains in the SLD. You have to clean up the data manually in the SLD.
Specify a Data Supplier Type .
Enter a date and optionally a time before which you want to display the systems that reported data to the SLD.
Set a Filter if you need.
Choose Go .
A list of systems is displayed along with the date on which they last reported data to the SLD.
If a particular date is too far in the past (see Scheduling the Data Collection Programs ), this is a good indication that the system no longer exists in the system landscape. The SLD has no way of knowing this, so you must manually remove the system from the SLD.
Select the system(s) you want to remove from the SLD.
Bear in mind that you remove not only the system but also all its associations to other systems, for example to business systems.
If you want to remove the selected system(s) and all their instances, choose Remove .
If you want to export the selected system(s) and all their instances:
Choose Export .
Choose Download Exported Data .
Save the file to a directory of your choice.
