How to Avoid Filters In Transport Import Queue

The biggest headache for an SAP Basis administrator is small system settings changes which was unknowingly done by a user in our SAP system.

So like that i faced an issue in STMS_IMPORT tcode screen and i dont know who was done this changes.
There is an issue like when an a filter settings are changed in STMS import requests it will not show the TP import status or it will not appear after import of the request.
so the developer or who ever is importing a TP in the corresponding system might complain about the issue.

Please follow the below steps to avoid such a filter issue in TP

1. Login to the corresponding system
2. Go to STMS tcode
3. Click Import overview or F5 
4. You will get the list of systems select the system which you have the issue or which system we logged in for issue.
5. Double click on it and you will be directed into STMS_IMPORT tcode screen
6. Go to EDIT Menu
7. Now you can see there is an option called "Delete All Filters"
8. It will be in Dark color if there is any filter settings are present for the system
9. Delete the filter by choosing this option and it will be changed to Gray color
10. Now you can see all the requests are displayed in the import queue of the system without any filters
11. The Delete all filters option will be grayed once the filters removed for the import queue
12. You can do it in the DC(Domain controller too)
