Doing a quick browse through my PPAP 4th edition manual, the only reference to this subject that I can find shows up in section 4.1 Note 2.
Note 2: All of the forms referenced in this document may be replaced by computer-generated facsimiles. Acceptability of these facsimilies is to be confirmed with the authorized customer representative prior to the first submission.
Third edition stated:
Note 2: All of the forms reference din this document may be replaced by computer-generated facsimiles. Acceptability of these facsimilies to to be confirmed with the responsible part approval activity prior to the first submission. The Automotive Industry Action Group (AIAG) offers for sale a diskette with the PPAP/APQP/FMEA forms.
So no real change there so far as meaning; they just took out the advertisement for the forms they sold (at a rather high cost if I remember correctly).
We use our own versions of the forms that were made in-house. Some of them are nearly identical copies of what AIAG manuals show (FMEA being one where we use an identical form), and others (our dimensional test results form) don't look remotely like the AIAG version but convey all the same information. Our PSW is in the same format but isn't 100% identical.
As long as all the information required in the 4th edition is being conveyed and your customer(s) are okay with the format of the form you are using, there should be no issue with current forms not matching the AIAG blue book ones 100%.
