How is the Unique ID used within
Down To Earth?
The Unique ID (UID) has two functions,
1) temporary filename extension and
2) higherarchy of transaction
security.
1) This three character field is used as the filename extension of
temporary work files within Down To Earth, usually in the WRK directory. For
example, the file generated when you print a report to screen, posting messages/log file,
and sorting results file.
2) The first position of the three character field controls which
user can proof and post other user's transactions. DTE compares your operator's UID to
the UID in each record in the transaction file for inclusion on a proof list or to
post.
Only
transactions entered with your UID or a UID whose first character has a
greater ASCII decimal
value ,
are included in your proof list or posting. Transactions
entered with a unique ID that has the same first character as your UID (equal ASCII
decimal value) are not included.
For example, you have four operators with the
Unique IDs of 0mj , 1sd , 1wr , and 2ts
...
>> the operator's unique ID
of 2ts sees only their own transactions. The ASCII value of the first
position of the unique ID (2) has the highest value (050) and the lowest priority of the
four.
>> the operator's unique ID
of 1sd sees and posts their own transactions plus those transactions
entered by the UID 2ts . The ASCII value of the first position (1) of the UID
1sd is 049 which has priority over any higher ASCII value, in our
example, 050.
>> the operator ID's unique
ID of 1wr sees their own transactions, those entered by the UID
2ts but not
the transactions entered by 1sd
. Even though the value of the first position of
the UID is the same priority as 1sd , the complete unique
ID is not the same. Therefore the transactions entered by UID 1sd cannot be seen or
posted by UID 1wr
.
>> the operator's UID
of 0mj sees transactions entered by all the operators in the example. The
ASCII value of 048 gives the highest priority.
