Extract taxe codes with NVV operation

[medkhaled]

Hello experts,

Does someone know how to extract all taxe codes with a specific operation key (NVV in my case)  OR with a specific operation type ? 

I checked many tables and was unable to find a link between tax codes and operation (NVV in my case)

IN FTXP, my tax code is linked to NVV,  but IN T030K my tax code is linked to VST (screen shots attached)

Regards,

In SAP, the NVV account key you see in FTXP isn’t directly stored in the tax code itself. Instead, it’s part of the tax procedure assigned to that tax code. Within the procedure, specific condition types (like MWST or NAV) are configured to use account keys such as NVV or VST. So when you select a tax code in FTXP, SAP displays the account key based on the condition type logic — not because the tax code is inherently linked to NVV. That’s why you might see VST in T030K even though NVV appears in FTXP — they’re tied to different condition types within the same procedure.”

Here’s how the components interact:

So, when you see NVV in FTXP, it’s because the condition type used in the tax procedure for that tax code is configured to post using NVV. The tax code itself doesn’t store NVV — it inherits it through this configuration chain.

This distinction is important when analyzing tax postings or troubleshooting inconsistencies:

• FTXP shows NVV → because of the condition type logic in the tax procedure.
• T030K shows VST → because another condition type in the same procedure may be using VST for deductible VAT.
