Prefilling Values

In a data entry application, it is possible to prefill fields using several approaches:

Make an ID field persistent, which uses the value entered for a previous case to prefill the value for a new case. The initial values of persistent fields can be specified in a PFF.
Make an ID field auto increment, which takes the value entered for a previous case and increments it by one to prefill the value for a new case. If no previous case has been entered, the value starts at 1.
Use the Key attribute of a PFF to specify the initial value of the case's ID items.
Use the Parameters section of a PFF to specify the initial values for non-repeating, non-persistent items.
Make a repeating field sequential, which automatically increments a field on a roster, incrementing it by one on each added occurrence.
Specify a value in the preproc of the field; for example:

PROC INTERVIEW_END_TIME

preproc

INTERVIEW_END_TIME = timestamp();
