1156: RequisitionLineCalculationService initiate beginning balance gets wrong previous period

Test Case #:1156	Test Case Name: RequisitionLineCalculationService initiate beginning balance gets wrong previous period
System: OpenLMIS	Subsystem: blue
Test case designed by: Anna Czyrko	Design Date: 09.11.2016
Short description: The initateBeginningBalance method in this service gets a list of periods earlier than the requisition's period start date (previous periods), takes the first one in the list, and assumes it is the most recent previous period. This assumption seems to be incorrect, as the external call orders the previous periods by start date ascending. So the first one in the list would be least recent previous period. Acceptance criteria: Refactor the code that gets the previous requisition to use the most recent previous period to determine the previous requisition Test Create two previous periods with different balances and check requisition uses the correct previous period to initiate a beginning balance

Pre – conditions:

Demo data should be updated to have two previous periods with line items for same products with different amounts of stock on hand.
