SSI TroubleShooting

SSI TroubleShooting

The table below describes a common SSI problem and what can be done about it.

Symptom

Network data gets rounded incorrectly when converting from Excel to

 

NMT'’s CNF file.

 

 

 

Probable Causes

The SSI user enters new connections or links in Excel using the SSI

 

macros. The user then runs NMT_Unload macro, and transfers the tarred

 

DBF file back to Unix. The user then enters the following commands:

 

run tar2nmt

 

 

run nmt

 

 

and then discovers that the hub IDs and data conn types have been

 

converted to integers.

 

For example, a HUB id:

 

4.3 -> 4

 

 

or a data connection type:

 

19.2 -> 19

 

 

 

Solution

To avoid this corruption, make sure that one of the following is true for

 

your link connection tables:

 

• The first line (not the column header's but the first data line) originally

 

came from NMT and has not been modified in Excel.

 

• All fields in the first line (again, first data line not field name line) with

 

this potential corruption (data conn type, all hub IDS and Feeder IDs)

 

have a single quote prepended to them. For example:

 

19.2

--> ‘19.2

This forces the DBF translation to treat these columns as strings, so truncation is avoided. This is only necessary in the first data line.
