Generate JMBG

The Generate JMBG masking activity allows you to generate JMBG numbers specific to Croatia.

Table of contents


To use the Generate JMBG masking activity, it must be placed inside a table masking activity or a similar activity that iterates over data. Once placed, select the property you want to mask. Next, select the gender (Male, Female, Any) since the generating the JMBG number depends on it.


In this example we want to generate JMBGs in the Customer table, so first we place the Customer masking activity and put the Generate JMBG masking activity within it. Once placed, we select the JMBG property and Gender.
