Today I was setting up the Dual-Write sync for one of my customers and I bumped into this error message:
Warning:[DWCE0001] Export was skipped. Max lookup count supported in Initial Sync stage is 10. Current lookup count 11
The issue here is that there is a limit in DataVerse that (I would guess) for performance issues there is a hard limit on a maximum of lookup fields.
In our case we had these fields in the default mapping for Customer V3 -> Account using lookup:
The workaround is to remove one of the problematic mappings, do the initial sync and add it back. Remember to take a screenshot of the mapping that you are removing so you can put it back exactly the same.
