system status not updated on the screen in the production order header

Hi,

I am working on a requirement where  production order change details should be updated  in SAP, when it is send from third party and inbound idoc is created in SAP with the same.

Initially Production order has CRTD system status in sap and now third party sends I0002 which means REL. This should be updated in production order instaead of CRTD.

But somehow CRTD status still exists in PO,but when i click on the status line, I can see both CRTD and REL check boxes are ticked. Ideally speaking REL should be seen in the system status instead of CRTD.

To update the status, I am using fm "STATUS_CHANGE_INTERN" where I am populating the new status in STATUS table. In the above screen,both are checked which not happen.

Can anyone please tell me why REL is not updated on screen, but when i see that bo th the check boxes are checked,becuase at a time only eesither of them should be checked.

Thanks in Advance.!!

Best regards,

Karthik Ganti.
