By default the sampling_strategy of SMOTE is not majority,

'not majority': resample all classes but the majority class

so, if the sample of the majority class is 812814, you'll have

Having the field value disappear just means that the custom field was not correctly implemented. When the system can't select/persist a record or a field it disappears when control focus is lost.

The DAC field type appears to be wrong. Usually string list uses small codes of about 2 or 3 letters string with fixed size: [PXDBString(3, IsFixed = true)]

Since you are setting the list dynamically you don't need to define null string values in the DAC: [PXStringList]

You need to make sure that your event is always providing the expected code values. This can be checked by removing the conditions and using constants for the SetList method call: https://stackoverflow.com/a/38089639/7376238

Maybe you missed some steps like creating the field in the database table. You can test with an unbound PXString field instead of a PXDBString like in this example to see if that's the issue: https://stackoverflow.com/a/49907964/7376238

In the child DAC's, the PXDefault should be PXDBDefault. This was a common problem for me when I got started. The difference for PXDBDefault is that it is "use to assign a value from the auto-generated key field".

Here is a very basic example of the child DAC field using PXDBDefault. The master table in this example is XXDocument, and the child table is XXLine. The key field is myID.

I have tried with in table and it worked for me

Maybe you are using "neptune." instead of "neptune"

My tests seem to work with "neptune"

You cannot use a dot in a column name without escaping it. It's probably best to rename the column so it is not using dots anymore, although you can also try to use backticks in the column name like this:
