• What is the cause and solution for SAP error message 26020 - & already allocated - further assignments ignored ?

  The SAP error message "26020 - Already allocated - further assignments ignored" typically occurs in the context of resource allocation, particularly when dealing with project management, production planning, or similar modules where resources (like materials, capacities, or personnel) are being assigned to tasks or orders.
  Cause:
  
  Duplicate Allocation: The error indicates that a resource has already been allocated to a particular task or order, and any further attempts to allocate the same resource are being ignored to prevent double allocation.
  Configuration Issues: There may be configuration settings in the system that are not allowing for multiple allocations of the same resource.
  Data Entry Errors: Users may inadvertently attempt to allocate the same resource multiple times due to misunderstanding the system's current state or due to incorrect data entry.
  
  Solution:
  
  Check Existing Allocations: Review the current allocations for the resource in question. Ensure that the resource is not already assigned to another task or order.
  Adjust Resource Allocation: If the resource needs to be allocated to a new task, consider deallocating it from the previous task first, if appropriate.
  Review Configuration Settings: If this error is occurring frequently, it may be worth reviewing the configuration settings related to resource allocation in the SAP system to ensure they align with business processes.
  User Training: Provide training to users on how to properly allocate resources and understand the implications of existing allocations.
  Consult Documentation: Refer to SAP documentation or help resources for specific guidance on handling resource allocation in the context of your specific module (e.g., Project System, Production Planning).
  
  Related Information:
  
  Transaction Codes: Depending on the module, you may be using different transaction codes (e.g., CJ20N for Project Management, CO02 for Production Orders) to manage allocations.
  SAP Notes: Check SAP Notes for any known issues or patches related to this error message. SAP frequently updates its knowledge base with solutions to common problems.
  System Logs: Review system logs for additional context or related error messages that may provide further insight into the issue.
