Why Descriptive Flexfields

Customers require more data to be stored than what Oracle provides

Oracle gave us additional “space” in most tables to store this data

Descriptive Flexfields will survive an upgrade

You don’t need to be a programmer :)


Planning

DFF space is finite, use wisely Does a DFF exist for your TABLE

forms look for [ ]forms look for [ ] TRMTRM DFF registrationDFF registration

DFFs are associated with a table NOT a form

Global vs Context SensitiveGlobal vs Context Sensitive

Global Data Elements mean the question will be asked for every occurrence of the Descriptive Flexfield.

Context Sensitive Elements are questions asked “depending” on the answer to some other question. This “other” question can use a Reference field from above for its answer.


AssignmentAssignment

My company has decided that we would like to know the make, model, and color of car the CFO of this set of books drives. I would like to know which state the CFO resides. If they live in Colorado I would like to know if they are a Bronco fan. If they live in Missouri I want to know if they are a Chiefs or Rams fan
