2858558 - Tax code from preliminary documents is not copied to billing documents

If the tax code is changed in preliminary documents, it's not copied to billing documents.

SAP S/4HANA Cloud Sales Billing

1. Go to app "Change Preliminary Billing Documents". Change the tax amount to some other value other than the defaulted one.
2. Go to app "Manage Preliminary Documents". Create a billing document with reference to the preliminary billing document.
3. Go to app "Display Billing Documents". The tax amout is not the value you changed.

When creating a billing document with reference to a preliminary billing document, the system uses the pricing type "G Copy price elements unchanged and redetermine taxes" internally. This is hard-coded. See SAP Note 24832 which explains different pricing types.

You can change the tax amount manually after the billing document is changed. Or as a workaround please check if you can make user of the data transfer cloud BAdI SD_BIL_DATA_TRANSFER (Custom Data Transfer for Billing Documents) and change the pricing type according to your own need.
