Exam MB-200 topic 6 question 16 discussion

correct

I don't see a list of options for this question, but your second suggestion appears to be incorrect. You cannot modify the schema name (which includes the publisher prefix as it was at the time the field was first created) after creating a field. Without knowing the options presented, I can't say what the right answer is, but in general it would be to modify the publisher prefix on the solution's publisher record, then delete the global option set and create it again from scratch with the new prefix.

Question is about "You create a global option set for a custom solution"

You said "I even have to say that it's better to create with another schema name since a couple of times I had problems with deleted and recreated fields on Dynamics CRM when importing it into production". What causes this is if you recreate a field with the same schema name but a different data type (even down to things like changing Date Only to Date and Time, simple to calculated, etc--not just the actual data type). However, for this scenario, you're right that you'd have to delete and recreate the field after changing the solution publisher profile's prefix to the correct value. At that point, you would have no choice but to give it a new schema name, since the prefix is now different than the original version of the option set!

delete it and recreate ;)
