So my belief only applies to PTFs that were temp applied and the superseded. If I skip a PTF, it's marked as superseded but never actually applied.

Thank you

Subject: Re: Removing superseded PTFs

IBM is correct. The key is understanding that a superseded PTF never actually existed on your system. If it HAD it would instead show Perm Applied.

Here's how it works. Consider these two systems:

"A" Has PTFs in this status.

"B" Has this
SI10001 Temp Apply

Now Both systems load and apply PTF SI10002 which SuperCedes PTF SI10001

Now they will look thus:

SI10001 Superceded
SI10002 Temp Apply

SI10001 Perm Apply
SI10002 Temp Apply.

The DIfference is that System "A" never had SI10001 on it at all. So it is simply marked in the PTF DB as "Superceded." This means that the FUNCION applied by that PTF IS present though provided by SI10002.

System "B" though DID have SI10001 so on that system it is Permanently Applied in the process of applying SI10002.

So if you then remove the SI10002 from the two systems they would then look like tihs:

"A" Has PTFs in this status.

"B" Has this
SI10001 Perm Apply

We have a bad PTF that I removed (SI70970). IBM support wants to send a superseding PTF as a test PTF (SI71481). IBM says if I delete the bad PTF and apply the test PTF, I'll end up with this:
SI71481 Temporarily applied (test PTF)
SI70970 Superseded (bad PTF)

If SI71481 is also a bad PTF, they say that removing SI71481 will also remove SI70970. This will cause IBM i to revert to the prior PTF (SI69828). PTFs would show:
SI71481 Not applied (test PTF)
SI70970 Superseded (bad PTF)

It's my understanding that superseded PTFs are permanently applied. I'm skeptical that removing the latest PTF would revert the superseded one. Are my wrong on this?
