Security Roles-AX 2012

Hi,

I'm trying to find out the security role for confirming a purchase order in AX 2012.

I checked with all the roles but not able to do the same and getting the below error.

...........Access denied to method cachingEnabled in class AifRuntimeCacheManager.............

Is it related to the workflow?

I would like to know regarding the same.

Thank You & Regards
