change PO distribution charge account

[AIMAM]

hello,

I need to change a distribution charge account for an IN Process PO; from the default account of the Master Inventory organaization.

If I have to do it from the backend, do I need to update another table besides po_distributions_all, and do I need to change any other column besides CODE_COMBINATION_ID.

Please advise me as I need to do this on the Production.

Thank you...
