Hi everyone!

I need some help with script that could help me add a new field to the document if a condition is met.

The idea of script is something like : "Take log messages in a dataframe grouped by field 'ID' of message and compare with a field 'suffix' (two possible options: an/ln) and if the 'ID' has both of them, create a new field 'state' with value approved if not then value should be disapproved.

Maybe it could be solved without the script.

Any help would be appreciated!
