Regular expressions use ^ as the starting metacharacter and $ as the ending metacharacter, but Celonis doesn't support end-of-line metacharacters. What are end-of-line metacharacters?

Hello @hiroaki.mori11 , did you manage to get the answer? I think the regex support in Celonis is limited to process matching not character matching.

Do you mind share your broader objective? There are few other alternative like using vertica sql during transformation or python ML package, it is depend on use case.
