How To Fix 6B123 - More than one letter exists for correspondence activity & (invoice print)

6B123 - Overview

• Message type: E = Error

• Message class: 6B - Real estate correspondence messages

• Message number: 123

• Message text: More than one letter exists for correspondence activity & (invoice print)

What causes this issue?

&V2& role and letter entries are assigned to correspondence activity
&V1& for invoice printout. However, only one entry is allowed.
Contrary to the other correspondence applications, in invoice printout
the recipient cannot be defined by the roles in the correspondence
activity. Each invoice can include several agreements, and is only
created for the corresponding customer. Therefore, the correspondence
activity is only used to choose the letter in the invoice printout
application.

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?

Assign exactly one letter to the correspondence activity in
Customizing. The "Role category" and "Role type" fields will not be
taken into account for the invoice printout, and should remain blank.
