I am having trouble merging two shapefile layers from ArcGIS 10.4 Online in ArcGIS 10.4 Desktop. Every time I attempt to execute the Merge an error message related to the content of one of my fields pops up. (Please see example below). The layers were created in a geodatabase and data was added using the Collector App. I have been editing the data on ArcGIS Online and never had any issues with the content of the fields until attempting the Merge. I would appreciate any suggestions.
either you are trying to add text to a numeric field
the contents you are trying to add are too big for the size of the field
solution is to save to a geodatabase or fix the shapefile structure prior to merging
