For our client we administer OTRS system.
Our client run a web shop
WEB shop system sends notification to client and to OTRS.
But we have a problem because order number on the confirmation to client is different from confirmation to OTRS. Difference is little but significant.
Format order number to client is ddddd/dddd and for OTRS is ddddd / dddd (space).
We have tried use PostMaster::PreFilterModule###000-ExternalTicketNumberRecognition but we can't find good RegEx for this.
Now we use ((\d{5}\s\/\s\d{4})|(\d{5}\/\d{4})) but this work only for this same format of order number. We would like to the order with format ddddd/dddd will be merge with ticket with order number with format ddddd / dddd (with space).
Is it possible ?
Could you help me ?
