Production settlement variance postings

Hi SDN,

Can anyone give me clues on how to set up FI GL postings on CO88 production order settlement that emulate the variances calculated as a result of the KKS1 variance calcs.  The

We use PCA but not COPA. 

In OBYC inventory offsetting GBB entries  general modification key AUA   set the production order settlement part of the journal, it is the other side of the CO88 settlement entries that I want to split out by calculated variances rather than being posted by material type.

e.g.   Price input variances I would like to go to a price variance account, and even if possible split via origin group according to the nature of materials used.

Thanks,

Brian Rowley
