We characterise bounded and compact generalised weighted composition operators acting from the weighted Bergman space  $A^p_\omega $, where
$A^p_\omega $, where  $0<p<\infty $ and
$0<p<\infty $ and  $\omega $ belongs to the class
$\omega $ belongs to the class  $\mathcal {D}$ of radial weights satisfying a two-sided doubling condition, to a Lebesgue space
$\mathcal {D}$ of radial weights satisfying a two-sided doubling condition, to a Lebesgue space  $L^q_\nu $. On the way, we establish a new embedding theorem on weighted Bergman spaces
$L^q_\nu $. On the way, we establish a new embedding theorem on weighted Bergman spaces  $A^p_\omega $ which generalises the well-known characterisation of the boundedness of the differentiation operator
$A^p_\omega $ which generalises the well-known characterisation of the boundedness of the differentiation operator  $D^n(f)=f^{(n)}$ from the classical weighted Bergman space
$D^n(f)=f^{(n)}$ from the classical weighted Bergman space  $A^p_\alpha $ to the Lebesgue space
$A^p_\alpha $ to the Lebesgue space  $L^q_\mu $, induced by a positive Borel measure
$L^q_\mu $, induced by a positive Borel measure  $\mu $, to the setting of doubling weights.
