Message text: TN &1 (&2): valuation not done, time recording must be positive
During the actual valuation of an ET (E-Learning) object, a check is
being done on the "Time Recording Type" (field TSCHT) entered within the
"General Attributes" (IT1685) infotype to ensure this recording type is
valid as only the "Positive Time Recording" (value "NO") is allowed for
such an ET object.
An error message was here raised because the "Time Recording Type"  is
not valid for the in-process ET object; this ET object was excluded from
the actual valuation.
In order to take into account the ET object during the actual valuation
process, its "Time Recording Type" in the "General Attributes" must be
set to "NO" ("Positive Time Recording").
The system issues an error message and will not allow you to continue with this transaction until the error is resolved.
