Creating a Default Rule for Blanks

When mapping with a default rule in dspMigrate, the action allows the user to assign a single value to all records containing that field. For example, a common default rule assigns the value of 'E' in the SPRAS (Language) Field in an SAP system, since other systems do not necessarily contain a separate language field.

But what if a user wants to assign a blank value (' ') to the field, perhaps to temporarily remediate null data or as a place holder, which would be converted to a manual rule for more complex operations? Thanks to the flexibility of the dspMigrate tool, this is easily achievable.

Map the field as a default rule and enter '<blank>' in the Default field in the Map section.

When generated by AutoGen, an update rule is created that inserts a single space into each record that contains the field for which the users intended for a blank.

Users can also enter in a single space (' ') when mapping this feature to achieve the same result.

Thanks Michael,

I would like to add that there are two additional options that we can use if we are using DSP 6.7.1 or higher.

These are:

<EMPTY> , in case you need '' instead of ' '. I find this particular useful as many times you need nothing instead of blank space.

<NULL> , for NULL values.

Regards
