G/L account and cost center field missing in 'Manage central purchase contracts' app.

Hi Guys,

In central procurement hub , while trying to create create a central contract I am changing the account assignment category from 'U' to 'K'. In this case I get an error while saving the contract that G/L account is missing. But I am unable to find it in the app. Could anybody please help me locate it in the app? Or is it just not possible to do it (as a standard functionality).

Note: We are using S/4HANA 1909.

Thanks and kind regards,

Somesh
