SO Line custom field removal

[indikad]

I have a line custom field on Jiwa 7 157 - that is of type Combo

It has about 5 selectable fields and been there for a while meaning users have used the selectable values to save data over time.
Now they wish to remove some and also change the names of some.
What could be the implications if I do.... ?

Hi Indika,

The values stored for a selected item is an index into the combobox items.

If you start off with 3 items in your combo with the underlying values "1", "2", "3" and the display values "a", "b", "c" - then any custom fields renamed will automatically display the new display value without problem, as the underlying value is still the same.

Removing an item such that the underlying value is no longer present will cause the displayed value to be blank when shown, but the underlying value will still be as it was. So, if using the above example data I removed combo item with value "2" and display value "b" - then reading a record which was referring to "2" will display as blank, but the data in the table will still be "2".
