Last modified: April 3, 2025

After you have configured data population and ouput options, you can view the action plan and warnings.

Action plan

On the Summary page of the Data Population wizard, switch to the Action Plan tab to review the action plan for the data generation.

It comprises the list of data population actions in the order they are to be performed. If you want to see the details of any action, click an arrow next to it to expand the list.

You can also click Expand all to see the description of all actions.

To locate a required action, you can type the search text in the Search box.

On the Summary page of the Data Population wizard, switch to the Warnings tab to view warnings, errors, or some information on what may cause data generation failure or data loss.

All generation warnings can be divided into three groups:

• warnings
• errors
• information

Warnings

• Check constraint warning: the following columns are excluded from generation.

• Generation of unique data is not possible. The Repeat values option is enabled.

• The generator selected for this column may generate improper values due to the CHECK constraint set for this column.

• The generation of composite unique values is not possible. The composite unique key with overlapped foreign key is not supported.

• The overlapped composite unique key is detected. Not all the generated values will be inserted into the database.

• A circular dependency has been detected. To populate data, enable the ‘Disable foreign keys’ option.

• Generating data for this table may fail because the table X is excluded.

Errors

• The column X will be excluded from the population process due to the error Y.

• This type of check constraints is not supported.

• Value is not specified.

• The table is not specified.

• The columns are not specified.

• The initial value must be less or equal to the final value.

• Generation of unique data is not possible. The Repeat values option is enabled.

• The column X does not exist.

• The X column cannot be included in the data generation process.

• Column is not selected.

• The folder X does not exist.

• The initial value must be less or equal to the final value.

• The percentage of excluded values should be between 1 and 99.

• The selected type of encryption is not FIPS-compliant. Please choose another.

• Column data type is not supported.

• Column refers to the X column of Y table for which the generation of data can not be performed.

• It is not possible to generate data due to the overlapped foreign key with the circular dependency.

• Column depends on X column of this table which is not included in the data generation.

• It is not possible to generate data with the selected generator due to a circular dependency. Please, select another generator.

• Column refers to the ‘X column of Y table for which the generation of data can not be performed.

• Options validation has been finished with unknown error.

• A circular dependency has been detected.

• A lookup table is not specified.

Information

• Not enough words to generate X proposals.

• There are duplicate values

• Computed columns cannot be intended to data generation.

• Server assigned columns cannot be intended to data generation.

• The data type of the column is not supported.

• Referenced column cannot be intended to data generation.

• Deleting data from this table may fail because it has child tables which are not checked.
