  The SAP error message SALV_X_API029 indicates that there is an issue with the data type of an amount field in the context of using the SAP ALV (ABAP List Viewer) framework. Specifically, it means that the field expected to contain a numeric value does not have a numeric data type, which is necessary for calculations or aggregations.
