Customize Mappings

While importing user might have data in different formats and want to apply lookup or customize data while importing from excel.

Use Lookup Tables

If you right click in a mapping field, the Use As Lookup dialog lets you mark the mapping entry to map the value from defined lookup information. Below the highlighted mapping entry is applied "lkup_Imperial_Sizes" to show sizes in fractional form. (e.g. size 0.5 as 1/2).

Using Expressions

With the help of expression based customization user can format data while importing into the catalog. For example if I want to customize SHORT_DESC field to have _IM attached at the end user can edit and apply the change by clicking the green check icon as shown below.

Use Arithmetic Expressions

Arithmetic expression allows user to customize data based on preliminary arithmetic operators (+, -, ;, *, and /). These arithmetic operations are performed on Numeric type of columns to provide numeric result otherwise it acts as text expression.

For example, if you want to multiply the PIPE_OD1 by factor 5 on importing to PIPE_OD_M column then use "<<PipeOD1>>*5" expression (without quotes) to get the desired results.
