We have just upgraded to Epicor 10. We have PO’s with multiple releases, some could be linked to a container and the others may not. In Epicor 9, we were able to receive the releases not linked to a container through PO Receipt Entry. Now, in Epicor 10, when we try to enter the receipt for a release not linked to a container through PO Receipt entry, we get this message PO Receipt Entry This Purchase Order has one or more associated Container Detail lines. Use Container Receipts to update receipt data for this PO. We are unable to go any further. This is affecting our current processes. Does anyone know if this is new functionality in E10 or if there is a setting I’m missing? I tried changing the settings for landed cost in company configuration but it did not affect anything. Thanks!
Try using this.

Are you sure your PO lines/releases are not checked as containers?
@jpredko
You are correct.
In E10, if you enter a container landed cost entry, then you can not use receipt entry for any of the other lines in the same PO.
The only option is to create different PO.
Thank you Craig. Unfortunately we do not want to use Container Receipt Entry as the release/line should not be linked to the container.
Yes, I made sure they were not.
Thank you. We were able to receive the unlinked lines in Receipt Entry in E9. Do you know when and why they would have changed this functionality?
I too ran into this issue after converting from Vantage to Kinetic.
Here is what I found in EpicCare.

Getting Associated Container Detail Lines Error in Receipt Entry
Version 1.0 • Updated: 2024-12-20 • 94 Views • ()() (*) ( ) ( )
Issue
Receipt Entry throws an error when trying to receive a Line on a given PO if any other Lines on that PO have been added to Container Landed Cost. This occurs even when the Line in question is not included on any Container.
Error
This Purchase Order has one or more associated Container Detail lines. Use Container Receipts to update receipt data for this PO.
Resolution
This is a design limitation now on E10, back on E9 customers were able to receive mixed POs in Receipt Entry (non-container Lines), but that got patched on E10, as it used to be considered a bug due to how fees/taxes are calculated.
Now the user needs different POs for each type of Part (container and not container), use the Container Receipt menu for those Parts that are coming in Containers, and use Receipt Entry for those that are not.
