Error while determinig Newly introduced condition value in PO

Dear Experts,

We've a requirement wherein we want to fetch the tax code in PO based on key combination ''plant/POrg/country/G/L Account'.

G/L account is not in the PO pricing filed catelogue list so we added this new condition in PO field catelogue,we've updated the tables KOMK and KOMP as appropriate.All the other config like maintaining access sequence etc is done.

MEK1 - Condition records are maintained with new key combination.

During PO creation we are getting error ''Access not made (initialized field), error message 102''.System is able to find the values for '''plant/POrg/country'' but not for newly introduced condition 'G/L account''.(Warning with yellow mark is appearing when I analyzed the pricing in PO)

Before posting this thread, I already searched for the other thread with the similar issue.I noticed to use USEREXIT_PRICING_PREPARE_TKOMP in include program MV45AFZZ to write some coding to fetch the exact G/L value.However we still are not able to get the results.

Would be very helpful if you can put some thought on this, is there any other solution/exit/enhancement available which can resolve the issue?

We need to give a demo to client by tomorrow, Your prompt response would be much much appreciated.Thanks

BR,
