How To Fix WFCS111 - Error transferring data when calculating forecast requirements

SAP Error Message - Details

• Message type: E = Error

• Message class: WFCS - Message Class for Store Forecasting (Dev. Package WFCS)

• Message number: 111

• Message text: Error transferring data when calculating forecast requirements

What causes this issue?

When calculating the forecast requirements for replenishment, the date
intervals for calculating the forecast quantities from the beginning of
planning to the end of the first or the beginning of the second time
interval were transferred incorrectly so that the system could not
calculate a result.

System Response

The system does not calculate a forecast requirement.

How to fix this error?

Adjust the master data so that the time intervals for the forecast
requirements are valid. If replenishment is to be used you also need to
maintain the data for calculating the replenishment lead time and check
the target range of coverage in the master data.

Procedure for System Administrators

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

• What is the cause and solution for SAP error message WFCS111 - Error transferring data when calculating forecast requirements ?

  The SAP error message WFCS111: Error transferring data when calculating forecast requirements typically occurs during the execution of forecast-related transactions or background jobs in the SAP system, particularly in the context of forecasting and planning (e.g., in SAP APO or SAP ERP Demand Planning).
  
  Cause
  The error WFCS111 usually indicates a problem in the data transfer or communication between different components or modules involved in the forecast calculation process. Common causes include:
  
  
  Data Inconsistency or Missing Data  
  
  The forecast calculation process expects certain master data or transactional data (e.g., product master, planning versions, historical data) which might be incomplete, inconsistent, or missing.
  
  
  
  Authorization Issues  
  
  The user or background job executing the forecast calculation may lack the necessary authorizations to read or write required data.
  
  
  
  Interface or Communication Problems  
  
  If the forecast calculation involves data transfer between systems (e.g., between SAP ERP and SAP APO), communication errors or interface failures (e.g., CIF errors) can cause this message.
  
  
  
  Incorrect or Incomplete Configuration  
  
  Forecasting settings, planning versions, or transfer rules may be incorrectly configured.
  
  
  
  Technical Issues  
  
  Problems with the underlying database, transport layers, or system buffers.
  
  
  
  
  Solution
  To resolve the WFCS111 error, consider the following steps:
  
  
  Check the Detailed Error Log  
  
  Look at the application log (transaction SLG1) or job logs to get more detailed information about the error context.
  
  
  
  Verify Master and Transaction Data  
  
  Ensure that all relevant master data (materials, planning versions, forecasting profiles) and historical data are complete and consistent.
  
  
  
  Check Authorizations  
  
  Verify that the user or job has the necessary authorizations for forecast calculation and data transfer.
  
  
  
  Review Configuration Settings  
  
  Check the forecast calculation settings, planning versions, and transfer rules in customizing (SPRO) or relevant transaction codes.
  
  
  
  Check Interfaces and Communication  
  
  If the process involves data transfer between systems (e.g., SAP ERP to APO), check the CIF queues (transaction CIFMON), ALE/IDoc status, and ensure that the communication is working properly.
  
  
  
  Re-run the Forecast Calculation  
  
  After correcting any issues, re-execute the forecast calculation.
  
  
  
  Apply SAP Notes  
  
  Search for relevant SAP Notes on the SAP Support Portal using the error message or component (e.g., forecasting, APO). Sometimes, known bugs or patches are available.
