Warn for duplicates on Sample Source name creation
When creating a sample source, the same Sample Source name can be created any number of times, which can lead to duplicate entries. A setting that enables a validation that only allows unique sample source names would be a great improvement for data quality. Even better if such a validation could either be applied system wide or only within specific user groups, depending on the setting
This is included in 7.5.2 as feature FP-282. Enforcing a unique sample name is now an option under Settings And Preferences -> General Preferences.
I too would find it useful to prevent duplicate sample source entries, so if a source donates multiple times, these occasions can be linked.
