Cause: A subprogram specification was
placed in a package specification, but the corresponding subprogram body was
not placed in the package body. The package body implements the package
specification. So, the package body must contain the definition of every
subprogram declared in the package specification.
Action: Check the spelling of the
subprogram name. If necessary, add the missing subprogram body to the package
body.
