Problem

How to Export action via the pmDataExporter uses REGEX expression as filter

Resolution

Please try the -f and -ff arguments, to specify the filter?

Like:

pmdataexporter -t Action -ff <field name> -f <pattern>

Note that the pattern follow the SQL convention and % is the match character. In your case, the pattern would be ‘CEN0019A%Traitement’ and field name is probably ‘Name’ or ‘Label’, depending on which you want to filter, the technical name or the friendly name.
