  The SAP error message E9873 indicates that there is an internal error related to a missing parameter in a function module (FM). The message specifies that you must enter one of the parameters (&1, &2, or &3) in the function module (&4). This error typically arises when a required parameter is not provided during the execution of a function module, leading to an internal inconsistency.
