I need to update environmental data in our system. The input data comes from an ESRI Shapefile, and I am using FME 2021.2. The output is stored in Oracle Spatial.

However, the system that reads the data from Oracle only accepts simple polygons. When I try to insert multipolygons, part of the geometry is ignored by that system.

Is there a way in FME to convert multipolygons into single polygons while maintaining a 1:1 relationship between input and output features?

If I use the Deaggregator, the number of records grows exponentially, which is not viable for our database.

I also started working with FME recently, so I may be missing a simpler or recommended approach.

What would be the recommended way in FME to transform multipolygons into valid simple polygons without increasing the number of features?
