In BPC 10 NW, EPM function to retrieve and show children of the parent in an input form?

Dear All,

In an input form, I need to display children of the parent member. Which EPM function can be used to achieve this?

i.e. If the user selects ÄSIA as entity in a cell, then I need to show the countries under ASIA in a column of cells. How can I achieve this using EPM function?

Thank you!

Regards,

Peri
