Why do you need this change?
Please do procedure InsertItemAttributeValueMapping as global. We need use this procedure in our extensions. Similar procedure DeleteItemAttributeValueMapping is as global. So we can delete records now, but we can't create them.
Describe the request
//local procedure InsertItemAttributeValueMapping(Item: Record Item; var TempItemAttributeValueToInsert: Record "Item Attribute Value" temporary)
procedure InsertItemAttributeValueMapping(Item: Record Item; var TempItemAttributeValueToInsert: Record "Item Attribute Value" temporary)
