This seems like is should be so simple, but I can’t get it to work! I want to take a CSV file that has Feature Class Names, FieldPrefixs, and Feature types. For example:
FeatureClass, Prefix, FeatureType
Roads, Road, Line
WildLandUrbanInterface, WUI, Polygon.
This CSV file will be dynamic, meaning that the Feature Classes that will be summarized will change.
I then have a SummaryPolygon Feature Class which defines the polygons on which to summarize. I want to iterate through the CSV file, summarize the data for each CSV record, and then add two fields with the prefixs (ie Road_Miles, Road_MilesPerAcre or WUI_Acres and WUI_PercentArea) to the SummaryPolygon. I thought the workspace runner would work well for this, but the Child workspace isn’t updating/showing the new fields that were created after each iteration. Meaning the schema isn’t dynamically updating with the two new fields on the next iteration. In my Reader, I have Workflow Options set to Single Merged Feature and Merge Feature Type checked with Merge Filter = * and FilterType = Wildcard.
All of the summarizing part works just fine, I just can’t figure out the iteration component.
Help?!
