Hi Sachin,
Sorry for delay in reply.
No, the issue still exists.
Please note
If we select any of the item after the billing action is completed then the fields are not editable.
But,without selecting any items if we check in the item tab then some fields are showing editable. Although it is not allowing to insert any new line item, the fields should ideally be freezed after billing action.
Please find the below screen shot .
As suggested by you I have checked the status of action in BILLING_CREATE in table - /DBM/OE_VBAPST. It has set to "C" (Completed).
Also the status for billing action in order header in table /DBM/OE_VBAKST is set to "C" (Completed).
