Sap Convergent Invoicing Process

[MM_M2C]

Hello everyone,

I need to carry out the following task in Convergent Invoicing:

Insert a zeroing line in the invoice, after the invoice has been calculated including VAT. I need the following information:

- Where to position myself within Convergent Invoicing in order to have the completed invoice including VAT. 

- Which standard functionality in Convergent Invoicing to call in order to write to DFKKOP and DFKKOPK, to insert the new zeroing invoice line and its posting

Example:
Total amount in Convergent Invoicing: €0.02

New line added via custom event: -€0.02
= Updated total amount: €0.00

If you want to post Zero invoice then CI custom event must create two line items as 0,01 and 0,01- same line items will be posted in DFKKOP table.
