CY745 - Overview

• Message type: E = Error

• Message class: CY - Capacity Requirements Planning

• Message number: 745

• Message text: Order & operation & suboperation &: No rem. available capacity available

What causes this issue?

The system could not find any remaining 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 commitment that already exists for capacity &V4&
or
check whether the formulas at the work center for calculating duration
or capacity requirements lead to different results. For example, if the
capacity requirements calculated are twice as large as the duration
calculated then two capacities are needed to execute the operation.
In this case you should increase the available capacity or change the
formulas.

CY745 - Details

• The SAP error message CY745 indicates that there is no remaining available capacity for a specific order, operation, or suboperation in the production planning module. This error typically arises during the scheduling or capacity planning processes when the system cannot allocate the required resources (like machines or labor) to complete the operation due to capacity constraints.
  Causes:
  
  Capacity Overload: The total capacity required for the operations exceeds the available capacity of the work center.
  Incorrect Capacity Planning: The work center may not have been set up correctly, or the capacity values may not reflect the actual available resources.
  Scheduling Conflicts: Other orders may be scheduled at the same time, leading to conflicts in resource allocation.
  Maintenance or Downtime: The work center may be undergoing maintenance or may be unavailable for other reasons.
  Incorrect Order Data: The order may have incorrect data regarding the required capacity or operation times.
  
  Solutions:
  
  Check Work Center Capacity: Review the capacity settings for
