# Generic errors codes

**50 - Lane without name**\
**Lanes** are used as roles names in **BpmFlow** then all **Processes** must have **Lanes** or can not be imported.

**54 - Pools wihout Lanes**\
Same reason as error 50.

**58 - Lanes with the same name**\
Lanes must have different names otherwise one will override the other while reading the XPDL file.

**62 - Pool without name**\
**Pools** must have a name.
