Why am I getting a validation error when I try to save custom fields?
Oracle Service Cloud all versions
When saving custom fields, an error is received: Only 9 Custom Fields can be Indexed per table.
This error is being returned due to the 9 custom fields per table indexing limit and it would be expected for it to happen.
As the error message informs us, we're allowed to index 9 custom fields for any given table at a time. Once we try to index a 10th field, this error will show up.
If you would still like to deploy the field, you can uncheck the 'Indexed' checkbox that can be found under the column name.
