It will if you specify GROUP. >My issue is with the reverse case where you are RESTORE'ing PTF2. >Right now this will ALSO restore PTF1 (and thus back out Element B >from PTF1) and possibly other PTFs that PTF1 PREs. You can restore PTF2 if PTF1 has been ACCEPTed. If PTF1 has not been accepted, you have to RESTORE PTF1 too. SMP/E will not do it for you. >To back out PTF2 >ALL that is needed is to select Element A from PTF1 and ignore PTF1's >Element B (since B is at PTF1 level even after PTF2 is APPLY'ed and >thus there is no need to remove it to remove the PTF2 level of >Element A). RESTORE does not take elements from PTFs. It takes them from the DLIB zone. >The way it works currently, RESTORE'ing PTF2, RESTOREs PTF1 which >triggers getting A and B from whoever PTF1 PRE'ed (who owned A and B >before PTF1 was APPLY'ed).

Wrong again. There is no requirement that the elements that are replaced during RESTORE come from a PTF that contains exactly the same elements that are in the PTF being RESTOREd. Evidently you have not performed RESTORE processing recently. I have. Yesterday, in fact. It ain't what you don't know that gets you into trouble. It's what you know for sure that just ain't so. - Mark Twain -- Tom Marchant ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
