Additional GL splitting criteria

Hi,

Is it possible to define additional GL splitting criteria?

I know that the standard paramters are:

-Posting date

-Company code

-Business Area

-G/L account

-currency

-Cost center

-Profit center

-Order

-Fund center

-Commitment item

And that event 945 provides the possibility of fields in structure FKKSUMKONT .

But is it possible to add additional parameters?

Regards,

Mario
