• What is the cause and solution for SAP error message PV090 - The waiting list has reached maximum capacity ?

  The SAP error message PV090, which states "The waiting list has reached maximum capacity," typically occurs in the context of SAP's scheduling and resource management, particularly in the Production Planning (PP) or Project System (PS) modules. This error indicates that the system has a limit on the number of entries that can be held in the waiting list for a particular operation or resource, and that limit has been reached.
  Cause:
  
  Maximum Capacity Reached: The waiting list for a specific operation or resource has reached its predefined limit. This can happen if there are too many requests or operations queued for processing.
  Configuration Settings: The maximum number of entries allowed in the waiting list may be set too low in the system configuration.
  Long-running Processes: If processes are taking longer than expected to complete, they may accumulate in the waiting list, leading to this error.
  Resource Constraints: Limited resources or capacity issues can lead to a backlog of operations waiting to be processed.
  
  Solution:
  
  
  Increase Waiting List Capacity: 
  
  You can adjust the configuration settings in the SAP system to increase the maximum number of entries allowed in the waiting list. This typically involves accessing the relevant configuration settings in the SAP system (e.g., using transaction codes like SPRO).
  
  
  
  Monitor and Optimize Processes:
  
  Review the processes that are causing the backlog. Identify any long-running jobs or operations that may be contributing to the issue and optimize them if possible.
  Ensure that resources are adequately allocated and that there are no bottlenecks in the production or project processes.
  
  
  
  Clear the Waiting List:
  
  If possible, clear out unnecessary entries from the waiting list. This may involve canceling or rescheduling certain operations that are not critical.
  
  
  
  Check for Errors:
  
  Investigate if there are any underlying issues causing delays in processing. This could include system errors, resource unavailability, or other operational issues.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or support resources for specific guidance on managing waiting lists and related configurations.
  
  
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as CO02 (Change Production Order), C223 (Maintain Capacity Planning), or C201 (Create Work Center) to manage production and resource planning.
  SAP Notes: Check SAP Notes for any known issues or patches related to this error message. SAP Notes can provide additional insights or solutions that may not be covered in standard documentation.
