When BOM data is entered or loaded, records for variable attributes for nodes and for positions are created automatically, with an initially empty value field. The attributes that are assigned depend on the data item.

For BOM nodes, records for all attributes that are assigned to the specific node type (B.10.03) are created. Additionally, all attributes along with their values that are present for the parent node are also propagated to the new node.

For BOM positions, records for all attributes that have been set up as discipline-dependent position attributes in B.10.04 are created. Additionally, all attributes and their values that are present for the BOM node to which the position belongs are also propagated to the new position.

Whenever an attribute value is changed, the modified value is propagated downwards through the BOM hierarchy such that all attributes that have not been changed on this lower level will also be updated accordingly; for example, modification of an attribute value on the topmost node of a BOM hierarchy will also update this attribute on all BOM nodes and BOM positions that are located beneath this root node and that are not locked.

The main purpose of this mechanism is to have all significant attributes that may be needed as a query criterion or as an MTO grouping criterion available on all levels of the Bill of Materials.
