Infor LX / BPCS Tip of the Week: Control Date Lead Times in LX

• Control Date Lead Times – LX provides five separate Control Date Lead Time fields so you can specify additional lead time values for Shop Orders, Purchase Orders and Planned and Firm Planned orders. Each Control Lead Time Date represents additional time (days) required at each step in the process that needs more time (Quarantine, Stabilize), that is to say, when a component is due, and when it can be used. (working with an aerospace  precision bearing manufacturer, I had to account for the QA requirement that no measurements could be taken until the parts had been “soaked” (stored) in an atmospheric controlled environment (72 degrees, and controlled humidity) for 24 hours. This requirement added one full day of lead time between each machining operation) The MPS/MRP Generation program, as well as programs that Shop Order Material Allocation records use the five control date lead times to adjust component required dates to function in the same way as the BOM Offset Lead Time.
   
• All programs that create MRP Planned Orders, MRP Firm Planned Orders, Shop Orders, and Purchase Orders call the Control Date Calculation program (MRP515B) to establish all five control dates. A Control Lead Time Date is used to adjust the component Required Dates data in the Material Requirements file (KMR), based on planned orders for a parent, and the FMA Required Dates data, based on shop order release dates for a parent.
