A building owner might own products that can be reused in the the project. In dRofus we call those these product existing Items.
Existing or transferable Items can be registered :
Registered trough an imported or individually entered into a dedicated Existing Item register in dRofus.
...
Associated to planned Items within Rooms.
Example on workflow: First register
Register all Existing Items which are to be relocated
...
Decide whether the Existing Items can be used to represent Occurrences of Items in the Project
...
,
...
establish a one to one relationship to planned Item and relocated Existing.
Net and Gross quantities are automatically adjusted to represent new and relocated quantities.
