We are facing issue in the customer invoice F2 and NOT in the inter-company invoice IV.
I understand that. I thought that SAP Note & other related SAP Note mention that, will be able to provide a hint to you.
Anyways, ideally for taxation cross company sales scenario, you should have following key combination for proper determination tax condition value in your main invoice:
9XX - SalesDocTy/Sales org./Distr. Chl/Plant/Sold-to pt
Note: this need to be placed above existing in sequence to current key combination.
As current key combination
Departure country (DE) - Destination country (PT)
or
Domestic taxes - Country (DE) - Tax Classification Customer (1) - Tax Classification Material (1)
may not be equip enough to cater cross company sales tax account determination.
I assume that under Germany's Double tax treaty, tax paid can be offset in one of two countries against tax payable in the other. Here you want to collect tax in Portugal company code (PT01)
Now, entries will be:
| SalesDocTy | Sales org | Distr. Chl | Plant | Sold-to pt | Tax Code |
|---|---|---|---|---|---|
| ZSTO | PT10 | 01 | DE10 | Portuguese Customer | L0/ L1/L2 Where, Country as Portugal |
In addition to that, check FTXP for your output tax code, are you able to see tax G/L account details for your tax condition type.
If you don't find any entry, then maintain the same.
Else. check with you FI teammate, whether correct tax G/L account are getting determine or not.
I hope this should help you.
Thanks, JP
