The DEL_ prefix
DEL_ is a special prefix. It is an abbreviation for Deleted and is used for application objects that will be deleted. After an object is prefixed with DEL_, it will be supported for a release and then deleted in the next version of the product.
DEL_ tables and fields are necessary to allow data update. Such objects allow access to old data that must be migrated to a new location.
When an object with a DEL_ prefix is introduced, the update mechanisms handle changes in the standard application, for example by moving fields and X++ code to the table that replaces the one with the DEL_ prefix. But, if you have written X++ code that references an application object that has been given a DEL_ prefix, you have to update these references yourself.
