* op01*capacity is not the maximum capacity of the unit - that´s simply "capacity". Just ignore the misleading VTT Wiki "On *p_unit* set *availability* to "1" and define *op00* and *op01* as the limits for operating shares, e.g. if the unit can operate at 40-100 % of maximum capasity, set *op00*=0,40 and *op01*=1,00."

# Common Backbone Error messages
# Common Backbone Error messages
* If GAMS studio shows you an error, you can click on the error message and see in which backbone line the error occured. Helpful to find the cause of the error.

***Domain Violation Error**
***Domain Violation Error**
* All grids, nodes, units etc. must be defined in the first sheets of the excel file (grid/node/unit etc.). A domain violation error indicates that in a later sheet (e.g. p_gnu_io), something was referenced, which was not defined in the first sheets. This can be either caused by a missing definition or by a spelling mistake (pay attention here: powerplant is for example not the same as power-plant). When clicking on the error message in GAMS studio, you can find the sheet that causes this error.
