Deleting record from PSA ?

Hi ,

Is it Possible to delete a particular Record from PSA Table.

Tried from my Side:-

1. I opened the Table using se16 and selected a particular record.

2. Then selected& expanded the Menu Entry Tab over there the Delete was there but Greyed out.So i could not delete.

Also if it is possible to Delete from PSA, will there be any issue once the record has bee Deleted.

Please Suggest?

Thanks ,
