WFCS111 - Overview

• 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.
