Minimal and additional site safety stock
Introduction
Site safety stocks (= site buffer) are the inventory level which, when reached, trigger a site resupply shipment. Site safety stocks are calculated dynamically for each period as:
Enrollment buffer and
Patient in treatment buffer.
In addition, users can manually set site safety stock levels per dispensing unit and per site group in dedicated tables as minimal and additional buffer.
Notes
Refer to the forecast calculation documentation section site demand forecasting for more details on how site buffers are calculated.

Dispensing Unit Code
Aliases
Dispensing Unit
Kit Type
Definition
Specifies which dispensing unit the minimal or additional safety stock setting applies to.
Rules
Must match an existing dispensing unit code as defined in dispensing units. If a non-valid dispensing unit code is entered, no interpretation error is shown, but the row will be ignored.
Site Group
Definition
Specifies which site group the minimal or additional safety stock setting applies to.
Rules
Must match an existing site group as defined in site groups. If a non-valid site group is entered, no interpretation error is shown, but the row will be ignored.
Additional Safety Stock
Definition
Specifies the quantity of additional safety stock defined for a dispensing unit and site group.
Rules
Must be an integer. If a non-valid entry is made, no interpretation error is shown and the interpreted value is 0.
In forecast calculations with RTSM data extract, if additional stock is specified for a kit type in the RTSM, but not in 4C Supply®, then the forecast calculation may underestimate the associated additional demand.
In forecast calculations with RTSM data extract, If additional stock is specified for a dispensing unit in 4C Supply®, but not in the RTSM, then the forecast calculation may overestimate the associated additional demand.
Notes
Refer to the 4C Supply® Forecast Calculation Manual for more details on how safety stocks are calculated when additional safety stocks are defined.
Minimum Safety Stock
Aliases
Minimal stock
Definition
Specifies the minimum safety stock defined for a dispensing unit and site group.
Rules
Must be an integer. If a non-valid entry is made, no interpretation error is shown and the interpreted value is 0.
In forecast calculations with RTSM data extract, if a minimum stock level is specified for a kit type in the RTSM, but not in 4C Supply®, then the forecast calculation may underestimate the associated additional demand.

Notes
Refer to the 4C Supply® Forecast Calculation Manual for more details on how safety stocks are calculated when minimum safety stocks are defined.
