BO special character

Hello everyone,

I want to know if there are some special character that we can't use in BO.

It seems that some Material Master data coming from SAP ERP are not present in BO database because they contain some special character on the matirial code (like "£" or "$").

Do you know if there are some restriction?

Thank you in advance for yor support.

Regards

Matteo Stocco
