Creation of Sub Contracting PO through Maintenance Order

Dear All,

I am aware of the sub contracting indicator to be cliked in the maintenance order in order for the system to generate a Sub Contracting PO through Maintenance Order. However I am unable to see this indicator in maintenance order fields.

Is there anything that I am missing in customising settings or is this related to activation of any business function sets.

I am working in ECC 6.0 EhP 5.0.

Need your help / inputs so as to resolve my issue.

Thanks in advance.

JK
