Hi All, I am trying to replace values which are already fields present in another field using rex and mode = sed.  Example I have two fields ID and error and both of them are Dynamic and Unique. Some ID's are found in the error field. Now I would like to replace the different ID's in the error field with a common String. | rex field=error mode=sed "s/ID/ My Id/g" If I type in a regular expression  it replaces a few but it is not very accurate and  that is why  I want to make use of the field which is Id itself. However it is not able to replace. Kindly assist on how to do the same. Thank you! ... View more
