The Excel macro version can not be determined

The system tried to determine the version of the Excel macro for
printing out shift plans, but the macro could not be found.
The version test and print process have been cancelled.
Contact the person responsible for the SAP front end installation in
your company. They can check for you whether the component "PD: MS
Excel Link" was installed during the front end installation. If not,
the component must be installed retroactively.
Note: if the component is installed, you will find in the SAP front end
directory (not in the current directory) files beginning with
"WDPDDMAC".
