PL/SQL event action

Hi ​@Ed22,

Here's how the PL/SQL block should look for this event action in IFS Cloud:

DECLARE
   print_tax_code_text_   VARCHAR2(5);
   invoice_id_            NUMBER;
   identity_              VARCHAR2(20);
BEGIN
   -- Get the identity from the new invoice being created
   -- (adjust parameter name based on your event's available parameters)
   identity_ := :IDENTITY;  -- or :CUSTOMER_ID depending on event parameters

   -- Query the VIEW to check the switch value
   BEGIN
      SELECT print_tax_code_text
      INTO   print_tax_code_text_
      FROM   identity_invoice_info
      WHERE  identity = identity_;
   EXCEPTION
      WHEN NO_DATA_FOUND THEN
         print_tax_code_text_ := 'FALSE';  -- treat missing record as FALSE
   END;

   -- If the switch is FALSE, raise an error to block invoice creation
   IF NVL(print_tax_code_text_, 'FALSE') = 'FALSE' THEN
      Error_SYS.Appl_General(
         lu_name_    => 'InvoiceCreation',
         msg_name_   => 'INVOICENOTCREATED',
         msg_value_  => 'Invoice was not created.'
      );
   END IF;
END;

Important: Error_SYS.Appl_General raises a standard IFS application error which will surface as a pop-up in the UI with your message text - exactly the behavior you want.

Hello, and in event action what should I add? 

or only new print_tax_code = TRUE?
