IS-U Billing with zero amount line items

Hello IS-U colleagues,

We're posting zero line items to some Sub-transactions from IS-U Billing.

The associated FI-CA document postings have 0.001 debt and 0.001 credit to the G/L Account configured for the consumption billing Sub-transaction.

The users do not want to see the 0.001 and 0.001- postings in the FI-CA invoice document.

Has anyone experienced this, and if so, do you have any suggestions on how to suppress this postings?

Thanks and regards,

Ivor Martin
