Override the Standard Aggregation Process for Consumption Items

[former_member1267742]

"The system always aggregates consumption items separately that differ in regard to one of the following characteristics:

• Consumption item class
• Business partner
• Contract account
• Subapplication
• Contract
• Rating group

All other fields, for which you do not enter an aggregation rule in the aggregation variant, remain empty in the aggregated item."

My question is based on the statement above posted on this link:

We are trying to test out a scenario wherein the aggregation will follow what has been stated above but for this case, we need to take out the "Contract Account" characteristic and the rest of the process will still follow the default one. Do you guys think this is possible? I am still a newbie in SAP Convergent Invoicing so forgive me if my question is poorly structured or something.
