Maintaining Tolerance key (OMR6) in currency other than Company code currency

Hi FI experts,

I have a requirement where we need to have all Tolerance key limits in USD rather than in their respective company code currency.

But as you all know, the currency field in OMR6 is always greyed out and fills automatically once company code is entered.

But I can see that the table corresponding to OMR6, has a currency fields which does not hold the currency which is maintained in OMR6 and is blank.

My question is: Is there a way by which we can enable the currency field in OMR6 and in turn can have desired currency for a particular company code.

I am not sure, but is there any config in SPRO to enable this field and remove autofilling using company code currency.

Regards,

Saurabh.
