Activate the Addresses > Plausibility check of the VAT ID no.
You have the option to inspect the VAT ID no. in the address basic data for correct formatting.
Activate this feature in BASIC DATA COMPANY > GENERAL COMPANY PARAMETER > SPECIALS > Checkbox [Check VAT-ID no.].
If this checkbox is activated, the application will automatically check the field VAT-ID no. upon entry in BASIC DATA ADDRESSES > ADDRESSES > ACCOUNTING.
If the Country field contains a country code of an EU member state, the check will be conducted directly after the data entry in the VAT-ID no. field.
The Country field does not entirely substitute the country prefix in the actual VAT ID no. The VAT ID no. must therefore contain the country code as well. The VAT ID numbers must be entered without blank spaces.
