• What is the cause and solution for SAP error message /SAPAPO/CDPSFIXING003 - First resource selected has been reached ?

  The SAP error message /SAPAPO/CDPSFIXING003 with the description "First resource selected has been reached" typically occurs in the context of SAP Advanced Planning and Optimization (APO), particularly during the process of capacity planning or production scheduling. This error indicates that the system has reached the limit of the first resource selected for a particular operation or production order.
  Cause:
  
  Resource Capacity Limit: The primary cause of this error is that the capacity of the first resource (e.g., a machine or labor resource) has been fully utilized, and no additional capacity is available for the planned operation.
  Incorrect Resource Allocation: The resource may not be correctly allocated or configured in the system, leading to an inability to schedule additional operations.
  Planning Parameters: The planning parameters set for the resource may not allow for additional capacity to be utilized, such as maximum capacity settings or shifts.
  Order Overlap: There may be overlapping orders that are consuming the same resource, leading to a situation where the first resource is fully booked.
  
  Solution:
  
  Check Resource Capacity: Review the capacity settings for the resource in question. Ensure that the capacity is sufficient for the planned operations. You may need to increase the available capacity or adjust the scheduling.
  Adjust Planning Parameters: Modify the planning parameters for the resource to allow for more flexibility in scheduling. This may include adjusting maximum capacity or shift settings.
  Reallocate Resources: If possible, consider reallocating the operation to a different resource that has available capacity.
  Review Production Orders: Check for any overlapping production orders that may be consuming the same resource. Adjust the scheduling of these orders to avoid conflicts.
  Use Alternative Resources: If the first resource is consistently reaching its capacity, consider using alternative resources or adding additional shifts to increase overall capacity.
  Consult Documentation: Refer to SAP documentation or support for specific configuration settings related to the resource in question.
  
  Related Information:
  
  Transaction Codes: You may want to use transaction codes like /SAPAPO/CC01 (Capacity Check) or /SAPAPO/CC02 (Change Capacity) to analyze and adjust resource capacities.
