I have had an export routine written to export my ebay listings, which I now have upgrade to support the new nop 3.1 structure and to cater with parent product ids. Pre 3.1 the import process was using the SKU (correct me if I am wrong) to detect parent SKU's and link them. Now it is using ParentProductId, which, when I generate an export file, there is no way of knowing this ID and therefore unable to link SKUs.
The suggestion given here is good but requires core code changes, and from past experience I rather not make these changes if I can avoid it. Reason is when upgrading Nop versions, the code needs to be merged and just creates an extra overhead when upgrading.
Does Nop have any plans to include this as standard functionality in future releases? Anyone have any other alternatives?
