Functional area inconsistency in EKKN and COAS table

Hi Experts,

When we create a PO, the Functional Area is maintained via Order. It is showing up correctly in Account Assignment tab in ME23n but is stored incorrectly in EKKN table with some other value. Ideally, it should be same but there is inconsistency. For eg, it comes up as CAPX in Order in COAS table and is saved as EQSV in EKKN table.

I am from ABAP, I tried to figure out where this value is populated using what logic but with no success.

Please help if you have any idea why this inconsistency exists.

Thank you in advance.
