Recently have come across when I go to Append a shapefile into a feature layer the number of Output Fields reduces to half when I click run. Even after deleting and replacing necessary fields.
Have deleted and re-downloaded the software and this doesn't seem to help.
Any theories or advice would be great, Thanks!
The data types might be a bit off e.g. dates aren't datetimes in shapefiles. Possibly try exporting the shapefile into a table/feature class within a file geodatabase then see if that solves it (more of a guess than anything).
