Chapter 3: Building Production Objects

Working with key columns and duplicate entries

When you make duplicate column entries in a column that has the Key option selected in the Column Information window, you see this message:

Duplicates found. Column[column_name] unique property removed.

This means that TRAN-IDE unselected the Key option for the column that contains duplicates. Click OK.

When you make duplicate entries in a column that does not have the Key option selected, but then edit the column and select the Key option, you see this message:

Col[column_name] has [#] duplicate[entry]. Edit duplicates now?

Select OK to open the Edit Duplicates window. If you click Cancel, TRAN-IDE unselects Key in the Column Information window.

When you edit duplicate keys, complete these options:

Item

Description

Column Name

Displays the column name. You cannot edit this information.

Row and Duplicate Value

Displays the duplicate column values.

  • Row – displays the ordinal position of the rows containing the duplicate values (the first row is always at 0 position).

  • Duplicate Value – displays the duplicate values.

Highlight the row containing the data you want to change, then use the Value field to edit the data.

Value

Displays the data in the highlighted row. Type a new value in the field.

When you finish, click Done to save the changes and close the window.

NoteIf a column has duplicate entries and the column is marked as a search (key) column in a filter or qualification object, the SFM performs a linear search of the table, otherwise, it performs a binary search, which takes less time.
