• What is the cause and solution for SAP error message CNV_CMIS_A_20123 - Cannot display data for all fields; table width too large ?

  The SAP error message CNV_CMIS_A_20123 indicates that the system is unable to display data for all fields in a table because the total width of the table exceeds the allowable limit for display. This typically occurs in the context of data migration or conversion processes, particularly when using the SAP Conversion Management Information System (CMIS).
  Cause:
  
  Table Width Exceeds Limit: The primary cause of this error is that the combined width of the fields in the table exceeds the maximum width that can be displayed in the SAP GUI or the specific transaction you are using.
  Data Structure: The structure of the data being processed may have too many fields or fields that are too wide, leading to an overall width that is too large for the display.
  
  Solution:
  
  Reduce the Number of Fields: If possible, limit the number of fields being displayed at one time. You can do this by selecting only the necessary fields for your analysis or report.
  Adjust Field Widths: If you have control over the data structure, consider reducing the width of certain fields, especially if they are unnecessarily wide.
  Use Pagination or Filtering: If the tool allows, implement pagination or filtering to break down the data into smaller, more manageable chunks that fit within the display limits.
  Check Configuration Settings: Review any configuration settings related to the display of data in the CMIS or the specific transaction you are using. There may be options to adjust how data is presented.
  Consult Documentation: Refer to SAP documentation or notes related to the specific version of the software you are using for any additional guidance or updates that may address this issue.
