SAP Error Message - Details

• Message type: E = Error

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

• Message number: 225

• Message text: Serious system or communication error (number: &1)

What causes this issue?

The system started the program in parallel processing mode. The program
attempts to start a new process from a main program to process the
processing packages (in the forecast, this is the list of materials for
a plant that is generated from the selection options entered in the
report). This operation was unsuccessful.
In technical terms, the program attempted to start a remote function
module (RFC) that was to be started asynchronously. However, there is
an error in the system which means that this operation cannot take
place.

System Response

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

How to fix this error?

WFCSL01) may be of help here, as they can give you more detailed
information about the error.
