"Entry Type" in CBIH82

Hi All,

In CBIH82 - "Entry Type" field, i am not able to change the "Entry type" after save, even when the status is in create/In Process status.

I want to change the  "Entry Type" field.

Note: No User Exit/ BADI has been activated, but still this problem exist.

Please provide your solutions.
