Delete D-file

In all cases where you already started fieldwork, without realizing that the interview numbers were duplicates, a more drastic measure can be used: delete the D-file. All interviews will start at the beginning of the questionnaire, including appointments that were made during the interview and for which interview data has already been collected.

The system checks for duplicate interview numbers. It does not check duplicate telephone numbers. In the NIPO FMS it is possible to check and remove duplicate telephone numbers, when using a Sample table instead of a T-file.

When using Sample table instead of T-file, you can initialize the Suspend Image for the records that should be re-used. But if the Suspend Image is not cleared, the same rules apply.

Re-using a T-file or Sample table record with the AlreadyCompletedCode setting, will not remove the data record from the U- and the O-file, so the same interview number might be used twice. Make sure that you have to remove duplicates before starting the analysis.
