Hello thanks for the answer, first of all I am trying to remove certain content from the fields here, for example so that in the field "Datum" the expression "Datum: " is no longer displayed. This is already at the top of the table and does not have to be written again and again in the content of the field. I have now used EVAL-fieldname in props.conf : I restarted Splunk and the error message (from above) did not show up anymore. However, nothing changes in my search on the web server -> the expressions I wanted to remove are still displayed. In addition, unfortunately, I do not know what is meant by SPL-query and macro. Many greetings btaxacher
