  The SAP error message CNV_10020607, which states "The maximum list width is &1 characters," typically occurs in the context of data migration or conversion processes, particularly when using the SAP S/4HANA Migration Cockpit or other data transfer tools. This error indicates that the width of a list (such as a table or report) exceeds the maximum allowed character limit set by the system.

  Exceeding Character Limit: The error is triggered when the output of a list or report exceeds the predefined maximum width. This can happen if there are too many columns or if the data in the columns is too wide.
  Configuration Settings: The maximum list width may be configured in the system settings, and the current configuration may not accommodate the data being processed.

  Adjust List Width: If possible, adjust the configuration settings to increase the maximum allowed list width. This may involve changing system parameters or settings in the relevant transaction codes.
  Limit Columns: Review the data being processed and consider limiting the number of columns in the output. This can help reduce the overall width of the list.
  Shorten Data Fields: If certain fields contain excessively long data, consider truncating or summarizing the data to fit within the allowed width.
  Check Data Mapping: Ensure that the data mapping and transformation rules are correctly defined to avoid generating overly wide lists.
  Consult Documentation: Refer to SAP documentation or notes related to the specific migration or conversion tool you are using for any additional configuration options or limitations.
