Entering Missing Values in Data Entry

By default, missing values are not allowed. However, if you select the Allow Missing Value for all Non-ID Fields Data Entry Build Option, you will be allowed to enter a missing value for any item that is not an identifier variable.

Enter missing value codes in one of the following ways:

  • Select Code|Missing
  • Click the Missing toolbar button Missing button in Data Entry
  • Enter a period (.) into the data field.

Tip: The Code|Missing command and Missing button in Data Entry button will be enabled only if missing values are allowed.

A period (.) will be written to the Data File for all missing data items.
