Because Syspro does not provide a valid table of valid warehouse bins, no validation of the starting bin is possible. Crossing our fingers that a mistake has not occurred, the user is moved to
Step 2: Input StockCode.
Step 2: Input StockCode, Qty Entered, Lot Number, Serial Number prompted
In order to minimize processing delays involved with a three tier architecture, software developers would simply present a screen which would capture all of the possible data items needed for completing the transaction. This forces warehouse employees to know that the item which they are moving is lot traceable and/or serialized. The screen shown to the warehouse employee is characterized by containing by required and non-require fields.
Developers at this time, could choose to determine
• if the item is lot traceable: (6 XML based hops)
• validate the stockcode/bin combination (6 XML based hops)
• validate the lot number/ stockcode/ bin/ qty input combination (6 XML based hops)
Grand Total 18 XML based hops.
In order to speed up the application responsiveness, developers could avoid the 18 XML based hops and aasume that the warehouse employee was able to input perfect data.
Warehouse user drives forklift 400 feet to the target bin.
Step 3: Input Target Bin
With all required data being available to the application, a posting request through the three tier architecture would be submitted. Score 6 XML hops to determine either if a transaction success is accepted or rejected.
If the developer has written the application to avoid the 18 XML based hops required for data validation, then the number of potential reasons for a failed transaction include:
• Invalid lot number
• Invalid StockCode
• Invalid StockCode/Bin combination
• Invalid StockCode/Bin/Lot Number combination
• Invalid quantity being moved
No audit trail for the bin transfer is generated.
In addition to the failure in updating Syspro for the bin transfer due to incorrect/invalid data, the forklift operator has not moved the inventory 400 feet to a new location. Since Syspro has not been updated with the bin transfer, the forklift operator should return the inventory back to the starting bin. This results in 800 feet traveled without a valid transaction.
