I have A field for Attachment in input form.

if I add any attachment to that attachment field, it should Add that attachment to sys_attachment and related table too.
How can I configure it.
Please help me out.

Hi @KeerthiPraV 

If you want to attach a file from an input form , you must use scripting. Direct field mapping does not work for attachments.

This is because attachments are stored in the sys_attachment table, so you need to explicitly add them using the Attachment API.

1. Create an Action Item with Type = Script.

2. Write a script inside the action to handle the attachment logic.

3. Use the  addAttachment()method to attach the file to the required target record.

• You have an attachment input field in the form

• You want to attach that file to a specific record (for example, a Change or Incident)

actionResult.addAttachment( "attachment_input_field", // Name of the attachment input field "change_request", // Target table name sys_id // Sys_id of the record where attachment should be added(target record) );

Using this approach ensures the attachment is correctly added to sys_attachment and linked to the intended record.
