Records and local rule
Original confirmed P400=400 was allocated to I1. Verified remittance instead names I2; both originally owed 400 and no further settlements or credits exist. The local process reverses the I1 allocation and creates an I2 allocation, retaining receipt P400 and the correction trail.
| Record | Amount | Reference |
|---|---|---|
| Confirmed receipt | 400 | P400 |
| Wrong allocation | 400 | I1 |
| Verified instruction | 400 | I2 |
Process the recorded case
- Verify corrected remittance identity
- Reverse the identified allocation link
- Create the supported new allocation
- Retain receipt and both change references
If other allocations have changed either open balance, recheck before moving the full amount.

What are final open bill amounts and received cash?
Show the worked answer
I1 reopens to 400; I2 becomes zero; confirmed receipt stays 400. Net allocation correction is −400+400=0, not a cash refund.
