Remember that 50 byte limit on emails from workflow?
Just a quick note to let everyone know that the 50 byte limit of emails sent from workflow (Send Mail step using object SELFITEM and method SendTaskDescription) has been increased. If you use expressions in your mail title it can often exceed the 50 byte limit at runtime so if these emails were send to your email system they would be truncated.
 Details of note 1609811
At the time of the definition, the mail title with the container expressions may be up to 120 bytes long. During the runtime, the expressions are replaces with values. Here, the system supports a length of up to 255 bytes. The new feature must be activated explicitly with SWPA. Finally, the maximum length also depends on the e-mail client. The SAP Business Workplace SBWP still only displays the first 50 bytes. However, if you post to an Internet address (TYPEID = ‘U’) or if you use the automatic forwarding to an Internet address (SO12), Microsoft Outlook, for example, can display up to 255 bytes.
Informative e-mail titles greatly facilitate working with e-mails Only adding container data makes it possible to search for, sort, and filter e-mails according to business-relevant criteria.
