  Cause:
  This error indicates that there is a restriction on the predecessor generation for a specific object (e.g., a project, task, or activity) identified by &1, and that this restriction is related to an end date &2. The error usually arises when:
  
  Date Constraints: The end date for the predecessor task is set in such a way that it does not allow for the generation of successors or related tasks beyond that date.
  Configuration Issues: There may be configuration settings in the project management module that restrict the generation of successors based on certain criteria, such as time frames or dependencies.

  Solution:
  To resolve this error, you can take the following steps:
  
  Check Dates: Review the end date &2 for the predecessor task &1. Ensure that it is set correctly and allows for the necessary scheduling of successor tasks.
  Adjust Predecessor Relationships: If the predecessor task is indeed supposed to allow for successors, you may need to adjust the relationships or dependencies to ensure they are valid.
  Review Configuration: Check the configuration settings in the project management module to see if there are any restrictions that need to be modified. This may involve consulting with your SAP administrator or project management team.
  Data Validation: Validate the data associated with the project or task to ensure there are no inconsistencies or errors that could be causing the issue.
