Overview: 

When using only dollar amount distributions the system doesn't acknowledge that all cost in accounted for and order will not open.
Fund distribution total validation should allow 2 cases: either totals in the currency add up, or percentages add up to 100%. Currently the first case is not supported (it used to be the only one supported before ).

Steps to Reproduce:

1. Log into some FOLIO environment as User X

2. Create order

3. Add order line with cost of $90

4. Add 3 fund distributions using percentage

5. Each Fund 33.33%

6. Save POL

7. Click action menu for order

8. Click Open

Expected Results: Order is opened and encumbered successfully. Three encumbrances, 1 for each fund for $30

 
Actual Results: Order fails to open. error shown "Fund distribution total must add to 100% or totalPrice"

Approach:

The same endpoint already implemented for mod-orders in scope of story: . Need to do the same for mod-invoice as well. 

Logic to validate fund distributions for mod-orders located in method: org.folio.orders.utils.FundDistributionUtils#validateFundDistributionTotal

Contract with endpoint for mod-orders attached as Postman collection in , we can reuse the same contract for mod-invoice response, request payload is different, to get request contract please take a look -> Create API contract for fund distribution validation
File with APIs -> fundValidationAPIContract.txt

Additional Information:

This was found in bugfest lotus release.

The new implementation should be callable directly by UI in a new endpoint. See .
