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.

I don't see anything specific given your criteria from the help file and I had a cursory look through the "What's new" sections for the various recent releases or Arcmap since you don't indicate the version you are using.  Check both again and to ensure that it isn't a version issue.  Also, the "More Like this" link to various threads to the right of your thread may provide similar issues information

Hi Dan, thank you for your response. I am using ArcMap 10.2.2 on Windows 8.1 x64. I couldn't find anything helpful in both files, nor any similar thread.

Hi Earl,

yes exactly, I am summarizing Shape_Area. Thank you for your explanation.
