unsatisfied forward or external declaration

compiler-errors, delphi

Solution

You have declared this method but didn't implement it.

Problem

I am getting an error while compiling `.pas` file. "unsatisfied forward or external declaration :TxxxException.CheckSchemeFinMethodDAException." Does anyone have any idea what this error implies? Does it mean that `CheckSchemeFinMethodDAException` was not called in all the concerned files?
