Hi Ravi,
Thanks for the reply & it was helpful:)
We can get the Validation error by the above expression. The AUOM contains multiple line items which is the part of tuple. The EAN Code only for the edited w.r.t to the AUOM it will throw an error.
It is not validating for the EAN Codes for the existing which is assigned to the other AUOM i.e. not modified particularly.
Thanks & Regards,
