=====Bills of Materials=====  
The first character of a row defines the row type and drives the processing of the row. If a comment token was defined, all rows beginning with the given character are skipped.

The following row types are supported:
  * H - Header row
  * I - Item row
  * S - Supplier row
  * R - Resource row
  * T - Text row
Every other first character, except the comment token, generates an error message.

====Item row type====
It represents a row on the grid of the Bill of Materials. The BoM row type is defined by the row sub type (second column) in the import file.

The first 15 column is the same for every-sub type. If the sub type of the row is operation, operation specific information can be added on the 16-39 columns.
