AUFK -PHAS3 is not getting updated when the order is closed using FM

Hi Experts,

We are using FM STATUS_CHANGE_INTERN to set the order status to 'CLSD' from 'CRTD' status, this is getting updated in JEST table however AUFK PHAS3 value is not getting reflected anything. In AUFK and AFIH, the order is still reading as CTRD and outstanding respectively.

Is tehre any alternative FM available to set the status to reflect in AUFK properly ?

Thanks,

Suresh
