I successfully set up an MBM and MBMEVENT for document 120 - blank variant. Every time a picking list is printed I get the streamfile MWS435PF in MNS206, as well as the MBM trigger file and the event is successfully sent to MEC. So, all settings to get the flow working are correctly set up.
What I am trying to do now, is to only send an MBM or MBMEVENT when the picking list is for a certain order type. We have many picking lists and I only need the trigger to do something special for a small quantity of picking lists. I saw 3 options:
1) Filter the events in EventAnalytics. However, none of the message key fields contain the information for filtering (order type or dispatch policy). I suppose there is no way to change the message fields of a standard MBM message or event?
2) It is an option to filter out the events in MEC itself, but this is not very performant.
3) I see that OOORTP is available as non-standard Partner Ref Obj in CRS928/CRS947 and then use it in CRS945. However, I cannot get this to work. Does anyone know how to use this OOORTP field?

Or are there any other options to only get a MBM or MBMEVENT when a picking list for a certain order type or dispatch policy is printed?
Thanks!
