include the Scheduling Margin Key to the LOIPR02

hello Experts,

I am trying to find some details on how to include the Scheduling Margin Key(SAP1 in our case) to the IDOC before passing it to the
ME.

Please let me know if there is any standard way of achiving this.

We are using : SAP ME 6.0 and MII 14.0

Thanks in advance,

Pradeep D
