Hi all - I've got a model where the nulls are mapped as zeroes, however when I write it out to an SDE, the nulls are still nulls.
I did try this with a Geodatabase, and it wrote the nulls out as zeroes, and I imported that into the SDE - all looked good until I re-ran it and the newly-made zeroes turned into nulls, despite the AttributeManager saying to write out zeroes.
I realise in writing this, the amount of times I put "nulls" and "zeroes" has probably caused you to space out.
