BUSY NDR ERROR Description
FALSE FALSE TRUE The job was ended with an error. The cause of the error can be
found in the STATUS parameter.
FALSE FALSE FALSE The FB was not assigned a (new) job.
Due to the asynchronous function of FB 68 TURCV, the data in the
receiver area are only consistent when the NDR parameter assumes the
value TRUE.
