!!Features of User Defined Fields *End users can create these and no special knowledge of the system is required *Date sensitive changes will carry forward the values *UserCalcs can read these values, but Workflow UserCalcs cannot access the NewValue of them *Can be accessed using the [P2K_SMGETUDF] function by external report writers and by [P2K_SMPUTUDF] by stored procedures to set the value. *Interface programs like [UEEF] and [UPPHF] can access these natively !Points opposed to User Defined Fields * The data is stored in an abstraction table and is not natively linked to the table it is related to. * This abstraction has the potential, if there are a lot of user defined fields, to impact performance. !!Setup and Use of a User Defined Field Use the [IMUF] screen to define the User Defined Field on the table you want the data related to. Note that in a parent-child table relationship where there are date-sensitive children, the parent table is often not permitted to have user defined fields (as seen on [IMCD]) You may also want to decide on [User Defined Columns|USER DEFINED COLUMN] as your extension structure instead.
