Hi Yi,
with "order change is now supported" I meant that hybris now allows to change an order. This wasn't there a few releases back. I didn't meant the integration capabilities of an order management scenario between hybris and ERP.
Here, when the order is created in hybris and transferred to ERP via iDoc thru the Data Hub, only complete order cancellations are implemented. This works in both directions, ECC>hybris and hybris>ECC.
No partial changes are supported in the integration scenario, meaning partial changes are not transferred between ECC and hybris. In the same way, partial deliveries are not supported in the standard integration content. So partial changes have to be implemented on project basis at this point in time (hybris 5.4 and 5.5). I suppose this is on the roadmap, but not planned for a concrete release so far, to my knowledge.
Best regards,
Ingo
