Box 1: Safety stock journal
Safety stock indicates an additional quantity of an item that is held in inventory to help reduce the risk that the item will go out of stock. Safety stock is used as a buffer in case sales orders come in, but the supplier can't meet the customer's requested ship date.
Safety stock indicates an additional quantity of an item that is held in inventory to help reduce the risk that the item will go out of stock. Safety stock is used as a buffer in case sales orders come in, but the supplier can't meet the customer's requested ship date.
You can to use the safety stock journal to calculate minimum coverage proposals based on historical transactions and then update the item coverage with the proposals.
Box 2: Demand forecasting
Key features of demand forecasting
Here are some of the main features of demand forecasting:
Generate a statistical baseline forecast that is based on historical data.
Use a dynamic set of forecast dimensions.
Visualize demand trends, confidence intervals, and adjustments of the forecast.
Authorize the adjusted forecast to be used in planning processes.
Remove outliers.
Create measurements of forecast accuracy.

Explanation
Box 1: Quality association
A quality association defines all the following information for a quality order that is generated:
The transaction event
The set of tests that must be performed on the items
The acceptable quality level (AQL)
The sampling plan
You must define a quality association for each variation in a business process that requires automatic generation of quality orders. For example, a quality order can be generated in the business processes for purchase orders, quarantine orders, sales orders, and production orders.
Box 2: Test variables
For every qualitative test that is defined on the Tests page, you must define a test variable and its possible outcomes (results). (For qualitative tests, the Type field on the Tests page is set to Option.) You use the Test variables page to set up, edit, and view the possible outcomes for a test variable that is associated with a qualitative test. For each outcome, you assign an outcome status of either Pass or Fail to indicate whether the test is passed or failed when that outcome is selected as a test result. You use the Test groups page to assign a test variable and a default outcome for it to an individual qualitative test.
For every test variable, we recommend that you define at least two outcomes: one that has an outcome status of Pass and one that has an outcome status of Fail. There is no limit on the total number of variables or outcomes that can be defined. Additionally, multiple tests can use the same test variables to record results.
Examples of test variables
Example
A manufacturing company performs two tests on manufactured materials. In one test, the pH level is associated with a color strip. Acceptable pH levels are in lighter colors, and unacceptable pH levels are in darker colors. In another test, multiple visual inspections are performed, and quality workers use their judgement to determine whether the item passes or fails the visual inspection.

Explanation
Box 1: Warehouse1
Set up warehouses for transfer orders.
You can use warehouse levels to create a hierarchy that supports transfer orders between warehouses. Based on this setup, master scheduling calculates item requirements at the individual warehouse level and generates planned transfer orders from an assigned source warehouse to fulfill them.
Click Inventory management > Setup > Inventory breakdown > Warehouses.
Select the warehouse that you want to refill.
On the Master planning FastTab, select the Refilling check box.
In the Main warehouse field, select the warehouse that you want to assign as the refilling warehouse.
Master scheduling calculates a transfer requirement for the selected warehouse and generates a planned transfer order from the assigned Main warehouse.
Note: If you clear the Refilling check box, the selected warehouse is assigned a warehouse level in regard to the Main warehouse, but the Main warehouse is not set up as a refilling warehouse.
Close the page to apply the new setup.
