How To Fix CY751 - Order & operation/phase & second. resource &: No rem. avail. cap. avail.

SAP Error Message - Details

• Message type: E = Error

• Message class: CY - Capacity Requirements Planning

• Message number: 751

• Message text: Order & operation/phase & second. resource &: No rem. avail. cap. avail.

What causes this issue?

The system could not find any available capacity within the planning
period.

How to fix this error?

Increase the size of the planning period or
increase the available capacity &V4& or
reschedule a capacity commitment that already exists for the capacity
&V4&
check whether the formulas in the work center for calculating the
duration or capacity requirements lead to diffrent results.

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

For example, if the capacity requirements calculated are twice as large
as the duration then two capacities are required to carry out the
operation. In this case you should increase the available capacity or
change the formulas.

• What is the cause and solution for SAP error message CY751 - Order & operation/phase & second. resource &: No rem. avail. cap. avail. ?

  The SAP error message CY751 indicates that there is no remaining available capacity for the specified order, operation/phase, and resource. This typically occurs in the context of production planning and scheduling when the system is unable to allocate the required resources to a specific operation due to capacity constraints.
  Causes:
  
  Capacity Overload: The resource (machine, labor, etc.) is already fully booked with other orders or operations, leading to no available capacity for the new order.
  Incorrect Capacity Planning: The capacity settings for the resource may not be configured correctly, leading to discrepancies in available capacity.
  Scheduling Conflicts: There may be overlapping operations or phases that are scheduled for the same resource at the same time.
  Resource Availability: The resource may be marked as unavailable due to maintenance, breakdowns, or other reasons.
  Incorrect Order Data: The order may have incorrect data regarding the required capacity or operation times.
  
  Solutions:
  
  Check Resource Availability: Review the capacity planning for the resource in question. Ensure that it is not overloaded and that there is sufficient capacity available for the new order.
  Adjust Scheduling: If possible, reschedule other orders or operations to free up capacity for the new order.
  Modify Order Data: Verify the order details, including operation times and required resources, to ensure they are accurate.
  Capacity Planning: Adjust the capacity settings for the resource if they are not aligned with the actual production capabilities.
  Use Alternative Resources: If the primary resource is unavailable, consider using alternative resources that can perform the same operation.
  Check Maintenance Schedules: Ensure that the resource is not scheduled for maintenance during the required time frame.
  
  Related Information:
  
  Transaction Codes: You can use transaction codes like CM01 (Capacity Planning) or CM21 (Capacity Leveling) to analyze and adjust capacity issues.
  Capacity Evaluation: Use reports to evaluate the capacity utilization of resources and identify bottlenecks.
  Master Data: Ensure that the master data for resources, including work centers and routing, is correctly maintained.
  Production Orders: Review the production orders and their scheduling to identify any conflicts or issues.
  
  By addressing the underlying causes and implementing the suggested solutions, you should be able to resolve the CY751 error and ensure that your production scheduling runs smoothly.
