Hi @cmorse26 

What is your Landed Cost Allocation Method? I don’t know if a customization will allow that field to be opened to manually update. 

The system will automatically allocate based on that. 

Have you tried to Override the Data Field? Clear the Value. 

@kbeatty21  - Thanks for the response.

You are correct in that it will only automatically allocate the amounts for each allocation method (except for “None”, in which it will automatically assign 0.00)

After discussing with Acumatica…

1. An import scenario will not work since it is a calculated field by the framework. 
2. An override of the field throw off the Total Allocated Amount calculation and the screen will not function properly. 
3. There is potential, via customization project, to manipulate the Allocated Amount at the line level and the Total Allocated Amount calculation together.

We are going to further explore a customization that utilizes a newly assigned “Custom” Allocation Method Type on the Landed Cost Code and opens up the ability to manually upload and/or assign the allocation amounts at the Details line level.

Thanks for your attention.
