Hi @RakeshChangeshpur,

• First  you need to add a custom action to the PurchaseOrderLinesHandling Projection(If you are creating an ExecuteAction type command with a custom action). Refer to the documentation here: 
  https://docs.ifs.com/techdocs/22r1/040_tailoring/225_configuration/300_projection_configurations/300_custom_action_configuration/
• Then you can add the custom command to the page using the Page Designer as described here: https://docs.ifs.com/techdocs/22r1/040_tailoring/225_configuration/200_client_configurations/300_commands/#command_group_display_label
  
  Depending on the command type you select, the first step might not be necessary.

The above documentations should give you a good idea about how to use this functionality. 

Hope this helps!
