Send mail with PDF attachment not correct for multiple address

Hello all,

When i try to send mail for multiple address and not correct in case there is one wrong address

(In my case the email address contain some chinese character ).

Ex: i have 10 address need to be sent and the number 5 is wrong then the address number 6 to 10 can not be sent although they are correct.So, I just send only from address 1 to 5.

My current FM is SO_NEW_DOCUMENT_SEND_API1. But i tried the class send mail BCL and i got same issue.

So, i tried to validate to avoid wrong address with FM : SX_INTERNET_ADDRESS_TO_NORMAL and i got issue that quite similar to issue send mail above.( if the address number fine is wrong then the address from 6 to 10 return with sy-subrc <> 0 although these address are correct).

Could you have me how to resolve this issue ?

Thank you so much.

Regards,

Tan Tai
