Selected Answer: D
There are several properties that can be customized on existing extended data types (EDTs) through extension: Label Help text Form help Country region codes String size You can only modify the value if the EDT does not extend from another EDT. You can only set the new String size to a value equal to or larger than the base EDT value. Decimals (NoOfDecimals property) For more information, see Extending decimal point precision for selected data types. You modify the properties as you would for newly added elements, using the property sheet.

The answer WAS D. I found that f.e. in 10.0.40 (10.0.1935.69) there is a new property 'String size is extensible' and a read only property 'Database string size'. This changes the behaviour. I could even reduce the length of a string in an extension.

I guess B can also be a right answer as we can modify the derived EDT and make changes accordingly which will not affect root EDT.

Selected Answer: B
Correct answer is B: AccountBase is already an EDT. By making an extension of AccountBase you will not be able to modify the string (field) size. By creating a derived EDT from AccountBase you will be able to modify the string (field) size. "You can only modify the value if the EDT does not EXTEND from another EDT."

You are saying completely opposite, by creating extension to the base EDT string size can be increased(but can't be decreased) but string size can't be modified on the derived EDTs

Should be B Because modifying is only possible in derived EDT, not extended
