DE Version Representing the Iteration of the File

SAS Name
DE_VRSN

Indicator representing the iteration of the file.

Comments

The second character of DE_VRSN ranges from ‘1’ to ‘9,’ then from ‘A’ to ‘Z’ to cover versions higher than nine. For example, a ninth version of a final file would be ‘F9,’ a tenth version would be ‘FA,’ an eleventh version would be ‘FB,’ and so forth.

An initial/original version of the Preliminary (P1) and Final (F1) DE TAF will always be generated. Subsequent versions (P2-P9; F2-F9) may be generated depending upon need.
