• What is the cause and solution for SAP error message /SAPAPO/DMRES134 - Change is not possible if avail. capacity intervals exist ?

  The SAP error message /SAPAPO/DMRES134 indicates that a change cannot be made because there are existing availability capacity intervals for the resource in question. This typically occurs in the context of SAP Advanced Planning and Optimization (APO), particularly when dealing with resource planning and capacity management.
  Cause:
  The error is triggered when you attempt to make changes to a resource (such as modifying its attributes, deleting it, or changing its capacity) while there are already defined availability intervals. These intervals represent the times when the resource is available for production or other activities, and they prevent changes to the resource's configuration to maintain data integrity.
  Solution:
  To resolve this error, you can follow these steps:
  
  
  Check Availability Intervals: 
  
  Navigate to the resource in question and check the availability intervals that are currently defined. You can do this in the SAP APO system by using transaction codes like /SAPAPO/RES01 (Resource Overview) or /SAPAPO/RES02 (Resource Planning).
  
  
  
  Delete or Adjust Intervals:
  
  If the availability intervals are no longer needed or can be adjusted, you can delete or modify them. Ensure that you have the necessary authorizations to make these changes.
  To delete an interval, select the interval and use the delete option. If you need to adjust it, modify the start and end times as necessary.
  
  
  
  Re-attempt the Change:
  
  After you have removed or adjusted the availability intervals, try to make the change to the resource again.
  
  
  
  Consult Documentation:
  
  If you are unsure about the implications of deleting or modifying availability intervals, consult your organization's documentation or reach out to a colleague with expertise in SAP APO.
  
  
  
  Check for Dependencies:
  
  Ensure that there are no other dependencies or processes that might be affected by the changes you are trying to make. This includes checking for any active production orders or planned orders that might be linked to the resource.
  
  
  
  Related Information:
