VAT number determination

Question

Hello Friends
I am bit confused with the determination of VAT number in the billing header. I have checked the F1 help but still bit confused.
The F1 help explains as below
Where the setting is BLANK, the following standard priority rules apply:
a) If PY has a VAT ID no. and PY <> SP, then tax number and tax classification are taken from PY (SH is no longer relevant in this case). The tax number is taken according to the 'tax destination country'. --> In my case PY has a VAT ID and PY = SP
b) If a) does not apply:
If SH has a VAT reg. no. or if SP has NO VAT reg. no., then the tax number and tax classification are taken from SH. --> SH has a VAT number and SP has a VAT number (same as Payer since Payer and SP are same in this case)
c) If b) also does not apply:
Tax number and tax classification are copied from the sold-to party. The tax number is taken according to the country of the sold-to party.
Which VAT number would system consider? Will it be SH ? as it is contrary to the point a) [as it says if PY <> SP take from PY and SH is no longer relevant, but here PY = SP so will it be SH?
Or b) says SH has a VAT number or if SP has NO VAT number then take it from SH -->will this rule be ignored as in my case SH has a VAT number and SP has ALSO VAT number
Which VAT number will I get in the billing header? Any hints
Thank you

Thanks for your time
Yes, it is Blank in the customizing, as per the priority rule which value would system consider in the mentioned scenario?
The delivery plant departure country and the destinatation country as same which is France. In my case system is taking the VAT number from Payer or Sold to party (PY and SP are same, so not sure whether SAP has taken PY or SP here) but I was expecting VAT number of Ship to party should be taken onto the billing header. I am sure why the system did not take SH, help from F1 also didnt clear my question
The note 434562 does not help here as I do not need sold to party VAT always but the correct one.
