In R3, I've added two new partner types that can be assigned to an order: Z4 - Reseller and Z7 - End User.
I've coded a user exit to populate these two fields.
The problem I am having is that on an order change, if the user changes only the customer numbers of these two partners, the 2LIS_11_VAITM extractor does not see that the order changed and does not send before/after images to BW.
I understand that these are not standard partner types which the extractor is coded to determine if there's been a change. However how can I make the extractor know that I want to send changes to these two partner types to BW?
