How To Fix CRM_EMAIL303 - Mail form &1 contains nodes that cannot be changed in the maintenance

SAP Error Message - Details

• Message type: E = Error

• Message class: CRM_EMAIL - Messages for Internet Marketing: E-mail

• Message number: 303

• Message text: Mail form &1 contains nodes that cannot be changed in the maintenance

What causes this issue?

Mail form & was created using a mail template. This template contains
nodes which can be used when maintaining a mail form, but which cannot
be changed.
This applies to the following types of node:
Alternatives
Commands
Program lines (code)
Folders
Loops
Tables
Templates
Sections
When creating an E-mail/letter/fax/SMS, the program logic lying behind
these nodes cannot always be carried out. This means that including
such nodes is not recommended and/or can lead to errors if they access
internal tables which are to be imported via the interface belonging to
the generated mail function module.
In contrast to smart forms, this interface is not supplied with data.
If, however, you fill your own internal tables in a node of node type
<LS>Program lines</> and if, in a subsequent node of node type
<LS>Tables</> you re-access these internal tables, then you can use
these nodes.
Do <ZH>not</> use nodes in the above-mentioned list which generate
output (like for example tables) for HTML mail forms because the
content cannot be output in HTML format.

System Response

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

How to fix this error?

Check whether the nodes you are using make sense and/or if their logic
is evaluated without errors. To do so, you can use the communication
channel test when creating mail forms. If the result is not as you
desire, delete the relevant nodes from the mail form.
