Based from my initial test, Item and Sales Kit code should have a unique code.   I would say that it is like Part Numbering System by which from my understanding should be unique for every item.  Did anyone creates a code that automate the numbering of Item Code / Sale Kit?.  On Set-up Tab - Form Setup, I saw that the user can control the sequence of each document number but still has an option to put different number if the user want to.  Can we do that as well in Item Code numbering?  I am not that good in PHP, so hope to get answer from this forum.  Thanks.
