*Planned Receipt Date isn't changing according to the new Lead Time Calculation parameter in Purchase Orders*

Hello!

I've bulk imported essential paramters like Lead Time Calculation , Safety Lead Time etc. of Items using Confguration Packages - Items.  However, I have problem in those existing Purchase Orders. Being specifically, the Planned Receipt Date isn't changing according to the new Lead Time Calculation parameter, it's just copying from the Promised Receit Date as if there is no Lead Time Calculation parameter.

By the way, those Purchase Orders were old documents created before my bulk import. To a certain extent, I am aware that system "protects" Receipt Date Columns of those "old" Purchase Orders somehow. But, I have to make those Receipt Date Columns of Purchase Orders change according to new Lead Time Calculation paramter. Once it works so, I will use them in Requistion Worksheet. 

With some settings somewhere, I should be able to choose whether Receipt Date Columns of those "old" Purchase Orders created before the bulk import should be affected by the new Lead Time Calculation, Safety Lead Time paramters etc. or not easily. 



What settings am I missing ? What should I do? Please help.

Additional info:

Lead Time Calcuation paramters of the items in the picture attached is 102D, Safety Lead Time is 30D.

I've encountered a similar problem in Purchase Orders before, and the Lead Time Calculation affected the Planned Receipt Date after we deleted the Location Code from the line and re-entered it. I tried this method but it didn't work this time however.

The changes you make on an Item AFTER a Purchase Document is created will have NO impact on the existing documents. The values on the Purchase Lines are validated at the time of entry.

If you want to update your existing Purchase Documents based on the new values, you will need to write a batch (development) to re-validate specific fields on the Purchase Lines or Purchase Header to trigger the system pulling the new values from the Item records.

If you are looking to test your new Lead Time Calculations (in a Sandbox Environment), you can use the Planning or Req. Worksheet, so when you change the Vendor No. on the worksheet line it will recalculate the Order Date based on the Due Date. This is a great way to check your dates without having to create the Purchase Documents.

Ben is correct, changing master data such as item cards doesn't affect existing open documents, it only affects new documents. You have several options, manually change the purchase orders, delete and create new purchase orders, or as Ben mentioned get a developer to create a processing report to push the item card changes to the purchase orders.

agree with Ben, the previous orders won't be affected by the new parameter.
