If a bundle is selected as an existing product, you can't change it to another value.

Hi

I am trying to update a custom field on a salesorderdetail record for bundle product for when order product is created or on update (bundle product not bundle items!)

Condition:

postImageEntity.GetAttributeValue<OptionSetValue>("producttypecode").Value == 2

{

//code

}

Same code works for producttypecode = 1

I don't touch the product bundle items which are read only, why this error ???

And should I do ?
