Hi All,
I am working on the L2 MB: INV01 Inventory ordering module (Section 3.3 Product Replenishment) and stuck at one of the subsections.
All the formulas seem to be working except for below senario.
Step 1 : I select "Submit Purchase Order Request?" Week 1 FY20 and can see that the "Confirm Purchase Order Receipt" is populated with correct values for Week 3 FY20 (Final Shipping Time Weeks is 2) as expected. Image1

Step 2 : I select "Submit Purchase Order Request?" Week 2 FY20 and check the "Override Shipping Method?" box and set the "Override Method" to "Air" and can see that the "Confirm Purchase Order Receipt" is populated with correct values for Week 3 FY20 (Final Shipping Time Weeks is 1) as expected. Image2

Step 3 : I then uncheck the "Submit Purchase Order Request?" Week 2 FY20 and the "Confirm Purchase Order Receipt" remains unchained as the underlying check box "Override Method" is still checked in the background as it was checked in step 2. Image3

I have attached following additional images for reference
Image4_Formulas - Formulas from Inv01_Inventory_Ordering
Image5_AccessDrivers - Access Drivers from Inv01_Inventory_Ordering
Image6_Inv_Order_Overrides - Overrides from AN02 Inventory Ordering Overrides
Not able to pinpoint what I may have missed. Any guidance is much appreciated.
Thanks
