Hi,
Go to that request monitor screen
Select data package from error stack monitoring
"SELECT ALL" on top right corner
Now you get all fields as blank value..now enter the value you want to change for that specific field..then Enter..Now you can see all records are changed to that new value on that column...
But this approach won't help if you want to empty the contents.....you might want to write ABAP code to do that or do it manually....
