  The SAP error message EM058 indicates that there is an issue with a field that is expected to contain a numeric value, but the content provided is not a valid number. This error typically arises during data entry or data import processes, especially when dealing with legacy systems or data migration.

  Data Type Mismatch: The field in question is defined to accept numeric values, but the input provided is either a string, special characters, or an empty value.

  Data Cleansing: If the data is coming from a legacy system, perform data cleansing to ensure that all numeric fields contain only valid numeric values. This may involve removing non-numeric characters or correcting formatting issues.
  Adjust Field Mapping: If the error occurs during data migration, check the mapping of fields to ensure that numeric fields in the source system are correctly mapped to numeric fields in SAP.
  Use Data Validation: Implement data validation checks before importing data into SAP to catch any non-numeric values early in the process.
