Automatic Postings to CO Object

Hello Experts,

I'm facing an issue to derive Cost Centre in automatic postings happening for Cost elements.

my CC hierarchy is defined like where CC are defined below Plant level, hence OKB9 settings do not serve the purpose to derive Correct CC using Valuation Area/Business Area as Criteria.

Eg: of CC Hierarchy Defination as:

Plant = Mumbai Location

CC defined = Andheri Location within Mumbai.

Hence there are scenarios where Automatic Postings are happening from MM and SD which requires Automatic Assignment to CO object for Cost element.

Kinldy help how can I find the workaround for this or else please correct if any wrong config done in the system.

Thanks.
