Difference in tax FF759

Hello,

I have a question in regards to error FF759.

I have correction invoice,

Position 100 is what was on original invoice and position 200 & 300 are the new ones from correction invoice.

What I did I have split line 100 per 1 amount on each line (200 & 300), same NET amount, but I have ended up with different tax amount.

And during posting I have an error FF759.

Pricing condition MWST for SD and MWST for FI are marked as group conditions.

I would appreciate any kind of feedback as I searched the notes 1472505, 515047, 872449.

Kind regards,

Mat
