Hi @Mazin ,

   Most of the data will be normalized by Servicenow content library (>85% in most of the cases). Still if you feel normalization is not correct or want to normalize the records which are important for your organization, then have a list of the publishers/products you want to normalize and then look whether these products are present in Software Products table or not, if they are not present then create the product in custom product table and then select these products on discovery model and normalize the record.
