Nowadays it exists 2 types of tabs:

• Head: is used to relate objects at the same level of hierarchy as the current object (brother). When access the object any relation is established between the source and the destin object.
  This type of tab is generally used for related documents, like Budget, Purchase and Invoice, for example.
• Item: is used for children objects. When access the object a relation is defined between parent and child object, so in case the destin object has no data the source object could be rebuild.
  This type of tab is generally used for the different entities that compose a document, like Invoice head, Invoice lines, Invoice discounts, etc.
