Under Purchasing Setup there is Document Style :
The version as shown below of the StyleEditPG.xml is 120.13.12010000.7
I uploaded the recent version of the xml from one of the patches which has the version as 120.13.12010000.9.
But even though I copied the latest version of xml its still showing the old one.
As its a OAG Page do just uploading the .xml will do?
