  The SAP error message CNVMBTCHECK023 indicates that there is a mismatch between the sender structure and the receiver structure during a data migration or conversion process. Specifically, it means that the sender structure (the source data format) is not properly assigned to the receiver structure (the target data format) in the context of a data migration project, often related to the SAP S/4HANA migration or other data transfer scenarios.
