Just curious, do most people just use the built-in UD table fields (CharacterXX, CheckboxXX, etc…), or do you Extend the table (add a field via “Extended UD Table Maintenance”)? The first doesn’t require doing a schema update (or whatever that is technically called). But you have to remember which CharacterXX field holds what data. You end up with code in customizations like `epiUltraComboC1.ValueMember = "ShortChar01"` * * * The second way would allow the code to be more readable: `epiUltraComboC1.ValueMember = "PM_Name_c"` But would require the schema update. Thoughts? ---

in 10 I ALWAYS make custom fields, there is negligible over-head to doing this (1 - 1 Join) and it makes everything so much easier ---

How do you manage the key fields? Keep an excel file cheat sheet? ---

You can modify the extended properties to tell you what’s there. ---

That 1 to 1 limitation exists to both styles of UD. Something we are working on - TBD. ---

I vote for > [@ckrusen](#): > > epiUltraComboC1.ValueMember = “ShortChar01” because any issues that could occur from it would be handled by a different Support team 😬😏 ---

Custom fields using UD Table Maintenance for the most part, but we do use UD tables in certain situations.
