Send email from SAP with attached document witch name length > 50 char

Hi,

I need to develop an abap program to send an email with an attachment.

The problem is that when I use the function SO_DOCUMENT_SEND_API1 or the method CREATE_DOCUMENT of class Cl_DOCUMENT_BCS, the attached document name is limited to 50 because of the data element SO_OBJ_DES.

Is there another solution to send an email ? Or a way to modify the document name length ?

Thanks in advance.
