Hi @Asterix ,

​​​​​​​Question1 

Were you referring to any Business rules associated to the QUOTE table? 

Question 2 

Can you please check the following Regular expressions for the character € :

/^\€?>0-9]p0-9,]*t0-9]\.?\0-9]{0,2}/I

Test Runs: // Only for the character €

€123 - True

123€ - True

^(-^\d\s]{1,}\s?�+-]?)(\d{1,3})(\,\d{3})*(\.\d{1,})?$ 

Test Runs: // For all the characters €, $, &

€123 - True

$123 - True

123 - False

&123 - True

I hope this might help you to adjust the RegEx as you wish.

Best Regards,

Shageesha
