Application of WPG 18.104.22.168 Fixpack does not work for a specific upgrade path wherein WPG 22.214.171.124 pak is explicitly applied.
Customers would not be able to upgrade to WPG 126.96.36.199, when any of the below upgrade paths are followed:
a. WPG 6.2.0.x to WPG 188.8.131.52 to WPG 184.108.40.206 to WPG 220.127.116.11
b. WPG 6.2.0.x to WPG 18.104.22.168 to WPG 22.214.171.124
An error message similar to below is seen on Update Installer panel :
"The APAR Enterprise that you are trying to select has been included in another maintenance package 6.2.1-WS-WPG-RP_Enterprise."
This problem is not applicable for other upgrade paths which does not involve WPG 126.96.36.199 pak application such as :
a. WPG 6.2.0.x to WPG 188.8.131.52 to WPG 184.108.40.206
b. WPG 6.2.0.x to WPG 220.127.116.11
This happens due to an incorrect build version label, because of which Update Installer does not proceed .
Resolution / Corrective action:
Download and use the refreshed WPG 18.104.22.168 PAK file as on July 5, 2012 . With this customers who have earlier applied WPG 22.214.171.124 PAK file explicitly , would be able to upgrade to WPG 126.96.36.199 level .
