Derivative variable generation method and device, terminal equipment and storage medium

Embodiments of the invention relate to a derivative variable generation method and apparatus, a terminal device and a storage medium. The method comprises the steps of obtaining to-be-generated target derivative variable information; according to the target derivative variable information, matching at least one piece of preset data field information required for generating a target derivative variable from a pre-constructed logic pool, and a pre-configured processing rule; according to each piece of preset data field information, calling a preset data field corresponding to the preset data field information from a preset storage path; and according to a pre-configured processing rule, processing the preset data field to generate a target derivative variable. Through the mode, the situation that the analysis module cannot work normally or the processing module cannot execute work due to the fact that the format of the original message or the data structure is changed is prevented. The generation process of the
