Preconditions:

1. Active fund having budget with $100 allocation and Allowable encumbrance = 110%
2. Open order with initial encumbrance $110 exists
3. An invoice related to open order (Release encumbrance is NOT active) exists

Steps to Reproduce:

1. Edit invoice line for invoice from Preconditions #3 => change "Sub-total" field value to "10" => Click "Save & close" button
2. Approve and pay edited invoice
3. Check that "Current encumbrance" amount in invoice line has "100" value
4. Cancel paid invoice
5. Click invoice line record  "Current encumbrance" link in "Fund distribution" accordion

Expected Results:

"Current encumbrance" link in "Fund distribution" accordion has "110" value (equal to "Initial encumbrance")
Actual Results:

 "Current encumbrance" link in "Fund distribution" accordion has "100" value
Additional Information:
Does not reproduce when "Release encumbrance" checkbox in invoice line is Active

Scenario 1 - Invoice is approved (Pending payment transactions exist)

Invoice amount = 10 (Pending payment)

Before cancellation

Encumbrance values:
Initial encumbrance = 110
Awaiting payment = 10
Expended = 15
Current encumbrance = 85

After cancellation

Encumbrance values:
Initial encumbrance = 110
Awaiting payment = 0
Expended = 15
Current encumbrance = 95

Scenario 2 - Invoice is Paid (Payment transactions exist)

Invoice amount = 15 (Payment)

Before cancellation

Encumbrance values:
Initial encumbrance = 110
Awaiting payment = 10
Expended = 15
Current encumbrance = 85

After cancellation

Encumbrance values:
Initial encumbrance = 110
Awaiting payment = 10
Expended = 0
Current encumbrance = 100

Scenario 3 - Invoice is Paid (Credit transactions exist) Note: we found an issue with this scenario. Expended having a min value of 0 could result in canceled credit invoices over stating the expended value. If before the credit it was 0 after the credit it technically should be negative and when canceled back to 0 but this is not happening. To resolve without causing rollover issues we will need to address with new functionality.

Invoice amount = -15 (Credit)

Before cancellation

Encumbrance values:
Initial encumbrance = 110
Awaiting payment = 10
Expended = 0
Current encumbrance = 115

After cancellation

Encumbrance values:
Initial encumbrance = 110
Awaiting payment = 10
Expended = 0
Current encumbrance = 100

Scenario 4 - 2 Invoices are Paid (Credit transactions exist)

Invoice amount = 15 (Payment)
Invoice amount = -15 (Credit)

Before cancellation

Encumbrance values:
Initial encumbrance = 110
Awaiting payment = 10
Expended = 0
Current encumbrance = 115

After cancellation

Encumbrance values:
Initial encumbrance = 110
Awaiting payment = 10
Expended = 15
Current encumbrance = 100
