AD066 - Overview

• Message type: E = Error

• Message class: AD - Data Dictionary application messages

• Message number: 066

• Message text: Output length for data type & is set to &

What causes this issue?

Some data types have a fixed length. For example, the date
always consists of 8 characters, that is, data type DATS is
stored as char(8). The output length is calculated from the
length of the data type and the required number of formatting
characters and, thus, also has a fixed length. For example, the
output length of DATS is fixed at 10 (8 figures plus two periods
to separate the year from the month and the month from the day).
You have specified an output length different from the
fixed output length for the data type you have selected.

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

System Response

The system sets the correct output length automatically and issues a
message.
