Short description:

an implementer (who is an authorized API user) can configure this field to appear in the Requisition template for their program
an implementer (who is an authorized API user) can configure it with a field label string
P is available to be associated with a requisition template by program
can be assigned a display order in the requisition form
average consumption is based on a period moving-average window of adjusted consumption (N) from most recent period(s)
- (N _t0 + N _t-1 + N _t-2 + N _t-(n-1)) / ( n )
user defines "n" (to indicate how many periods will be averaged)
"n" cannot be 1 or 0, must be greater than or equal to 2
"n" must have a value if (P) is selected to be displayed/included in the template
n = number of periods
t = indicates relative period (_t0 = current reporting period)

For data entry, if not enough periods exist, compute based on the following:

if no previous periods, and there is only _t0 ; use P = N (instead of the formula above)
if one previous period, so _t0 and _t-1 ; use P = Roundup( (N _t0 + N _t-1) / 2)
if more than one previous period, just compute the average of what periods are available (even if less than the defined "n")

Pre – conditions:

Step	Action	Expected system response	Comment
1	Add column "Average Consumption" to the Requisition Template

Column is added to the requisition Template.


2	Initiate requisition and

veirfy

verify if the column is available.

After initiation, Average Consumption column is visible .
3

Delete

Remove the column "Average Consumption" from Requisition Template (unselect the checkbox).	Image Added
4	initiate a new requisition and check if column is not displayed.	Image Added
5	Change the display order for "Average Consumption" and: check if for old requisition, the order display is still the same check for new, initiated requisition if the order display is changed	Image Added Image Added
6	Set the n=1 in requisitionTemplate for Family Planning.	It's not possible to save the Requisition Template when number of periods to average is set to 1. Image Modified
7	Set the n=0 or leave it empty in requisitionTemplate for Family Planning.	It's not possible to save the Requisition Template when number of periods to average is set to 0 or leave it empty. Image Modified OR Image Modified
8	Set the n =2 and save the changes in Family Planning.	Image Added
9	Initiate a new requisition and calculate the Average Consumption.	The Average Consumption is calculated properly (45+11)/2 = 28 Image Added	The AverageConsumption is the average of the Adjusted Consumption from last periods. The Adjustment Consumption is the multiplying of Total Consumed Quantity and Total Stockout Days from current period. The Adjusted Consumption from last period(July) is set to 45. Image Added
10	Set the n=5.	Image Added
11	Initiate a new requisition and calculate the Average Consumption (the previous periods should contain all needed values)	The Average Consumption has been calculated properly. Average Consumption is set to 15.4 (11+5+4+33+24)/5 = 15.4 Image Modified	When n=5 and Adjusted COnsumption for product with productCode C600 is set to: N= 11 for August Image Modified N=5 for September Image Modified N=4 for October Image Modified N=33 for November Image Modified N=24 for December (current period) Image Modified
12	Initiate a new requisition, calculate the Adjusted Consumption

, submit requisition and skip the requisition.13Initiate another new requisition and check14

when previous periods are skipped (n=2).	When previously periods are skipped, the calculation for Average Consumption are based only of current period. Image Added
