• What is the cause and solution for SAP error message CJ558 - Field length exceeded when calculating project & duration ?

  The SAP error message CJ558 ("Field length exceeded when calculating project & duration") typically occurs in the context of project management within SAP, particularly when dealing with project structures, activities, or durations that exceed the defined limits in the system.
  Cause:
  
  
  Field Length Limitations: The error is often triggered when the total duration of a project or the number of activities exceeds the maximum allowable field length defined in the SAP system. This can happen if:
  
  The project has an excessive number of activities.

  Data Entry Errors: Sometimes, incorrect data entry or configuration settings can lead to this error. For example, if a user mistakenly inputs an unrealistic duration for a task.
  
  
  Customizations: If the SAP system has been customized, there may be additional constraints or limits that are not present in the standard configuration.
  
  
  Solution:
  
  
  Review Project Structure: Check the project structure and ensure that the number of activities and their durations are within reasonable limits. Consider breaking down large projects into smaller, more manageable sub-projects.
