This error indicates that the system requires both the prevention type and the period to be specified together in the planning data.
  Cause:
  The error arises when:
  
  You attempt to enter planning data without specifying both the prevention type (which indicates the type of cost or revenue prevention) and the corresponding period (which indicates the time frame for the planning).

  To resolve this error, you should:
  
  Check Your Input: Ensure that when you are entering planning data, you have both the prevention type and the period specified. 
  Review the Planning Layout: If you are using a planning layout or template, make sure that it includes fields for both prevention type and period, and that you are filling them out correctly.
  Consult Documentation: Refer to the SAP documentation or help files related to the specific planning transaction you are using to understand the required fields and their relationships.
  Adjust Configuration: If you are a system administrator or have access to configuration settings, check if there are any settings related to planning that might enforce this requirement. You may need to adjust the configuration to allow for more flexible input if appropriate.
  
  Related Information:
  
  Transaction Codes: The error may occur in various transaction codes related to planning, such as CJ20N (Project Builder), KP06 (Cost Center Planning), or others depending on your specific use case.
  SAP Notes: Check for any relevant SAP Notes that might address this error or provide additional context or solutions.
  User Roles and Authorizations: Ensure that the user has the necessary authorizations to perform the planning activities, as sometimes restrictions can lead to incomplete data entry.
