Hi @killphil84​ 

I do not have instructions specific to the ArcSDE geodatabase, but this article is handling a similar error but with the ArcGIS Online dataset.

You should be able to follow the instructions for using

AttributeValidator -- Set up rules based on existing table schema

AttributeManager -- Use Arthematic Editor to convert datatype numeric to float

Instead of going through all attributes, you should be able to use SchemaReader and filter DataType floats

Thanks a lot for yout reply. In the process of using the AttributeValidator und AttributeManager as you suggested, I was able to locate the problem. My workbench tries to write values such as 1.0106675843510633e-16 (values like this ar corret and quite common concerning the task I'm working at atm) into the ArcSDE Database, but the properties of the DB-colums doesn't match here. It occurs that some columns doesn't allow enough digits/decimal places to save the given values. I don't have any control over the ArcSDE DB, so I've connected the admin to discuss possible solutions.

hi @killphil84​ 

AttributeRounder is an option if it fits your workflow.

Well, although my questian was posted quite a few days ago, I'd like to present my solution: I've used a tester on the attributes which values potentially cause problems and test for "value < 0.000000000000000000000000000001". When this is the case, I've just put 999999999 as value via attributecreator and ducumented this value as indication for values that are too small to be written to the database.
