Multipart To Singlepart using in_memory as output location

OlegMueller

Hi all,

I am using the "Multipart To Singlepart" tool in model builder. If I am using the in_memory store as output location, the processing of the next tool "Summary Statistics" fails because the Field is missing. When I choose a personal geodatabase as output location everything is working fine. I do not understand why the memory store is failing. This happens just at the beginning of the model, so this is not a memory constraint problem.

thx

It sounds like you're trying to summarize one or more of the fields that are automatically added by ArcGIS, such as Shape_Length, Shape_Area, etc.   An in_memory feature class doesn't have these attributes.  I suspect they are created when the feature class is actually witten to disk.  

To summarize any of those fields, you'll need to direct the output of "multipart to singlepart" to your scratch workspace or to some other persistent geodatabase.
