This message is generated when the boundary conditions in the specification of the solution of a partial differential equation are given at points that are not on the edge of the domain of the solution.
Off[message] switches off the message; On[message] switches it on. For example: Off[NDSolve::bcedge].

This input generates a warning message because of the condition on f[0,0]:
The problem can be resolved by simply discarding the condition on f[0,0], since this condition is redundant with other equations in the input:
Evaluation of this input will show a plot of the solution:
