• What is the cause and solution for SAP error message WRF_APC136 - ?

  SAP Error Message: WRF_APC136
  
  1. Cause of the Error
  The error message WRF_APC136 typically occurs in the context of SAP Advanced Planning and Optimization (APO), specifically within the Production Planning and Detailed Scheduling (PP/DS) or Supply Network Planning (SNP) modules.
  Meaning:
  
  The message usually indicates that a certain resource or capacity is overbooked or that a planned order or production order cannot be created or confirmed due to capacity constraints.
  Typical cause:  
  
  The system detects that the available capacity of a resource (machine, work center, production line) is insufficient to accommodate the planned load.
  The capacity check during order creation or confirmation fails because the load exceeds the available capacity.
  It can also occur if the capacity data is missing, incorrect, or not maintained properly.
  
  
  2. Solution
  To resolve the WRF_APC136 error, consider the following steps:
  
  
  Check Capacity Data:
  
  Verify that the capacity data for the resource is correctly maintained in the system.
  Ensure that the available capacity is realistic and updated.
  
  
  
  Adjust Capacity or Load:
  
  Increase the available capacity for the resource if possible (e.g., add shifts, increase working hours).
  Reduce the load by rescheduling or redistributing planned orders to other resources or time periods.
  
  
  
  Check Planning Parameters:
  
  Review the planning parameters and heuristics used in APO to ensure they are set correctly.
  Adjust the planning horizon or bucket size if necessary.
  
  
  
  Use Capacity Leveling:
  
  Run capacity leveling or rough-cut capacity planning to balance the load across resources.
  
  
  
  Check Integration and Master Data:
  
  Ensure that master data such as work centers, resources, and capacity categories are correctly maintained.
  Verify that the integration between SAP ERP and APO is consistent.
  
  
  
  Debugging and Logs:
  
  If the error persists, check the detailed logs or debug the planning run to identify the exact cause.
