I tried changing the name of an itemtype of SellerInformation to UssidInformation and all its references too.
Product and UssidInformation itemtype is having one to many relation with source element qualifier as productSource and target element as qualifier ussidInfo.
I gave initialization. In hmc , type has got created and in UssidInformation table the attribute productSource is present.
But when dto is converting to model it is throwing exception "Caused by: de.hybris.platform.servicelayer.exceptions.ModelSavingException: no attribute Product.productSource found".
Please can you provide me a solution.
