Hello, Im getting the next error

Invalid item reference key 3129678 for subsidiary 3.

Im trying to set an item on a SO, I did my research and found that this error can be caused by two things, if the item is not associated with the subsidiary directly, or if the customer subsidiary is not a child of a parent subsidiary which the item is associated with., but in this case, the subsidiary

3

is the customer subsidiary and this is a direct child of the item’s subsidiary which it has an id of

2

Also it says that the item income account shouldnt be empty and this is not the case! Any idea why else this could be happening?
