Adding fields to Release Project Business Object is giving customer the following error
There is a 256 field limit on Business Objects. This includes hidden fields which the Administrator will not see. For example: Any link field and validated field will store two values. Link fields create a _RecID and _Category field. When you set a field to be validated, it creates another field _Valid, so two fields are required for all validated items as well. Localization may also take up additional fields, depending on the object. The field count will be related to the number of locales enabled. , _fr, _es, _de, etc... You can use additional 1:1 related tables for extensions such as "Details", similarly to the Incident Business Object.
