Validation rules are enforced during MBO development, and, in some cases, when you deploy the MBO to SAP Mobile Server. Messages are generated when validation rules are violated.
| Severity and message |
|---|
| Error: Argument ''{0}'' cannot be mapped to a client parameter; only top-level arguments can be mapped to client parameters. |
| Error: Repeating argument ''{0}'' cannot be mapped to an attribute unless an element of repeating argument ''{1}'' is mapped to an attribute. |
| Error: Attribute ''{0}'' of repeating mobile business object ''{1}'' can only be mapped into a repeating argument for operation ''{2}''. |
| Error: Attributes of the same cardinality (''{0}'', ''{1}'') cannot be mapped into arguments of different cardinality (''{2}'', ''{3}'') within the same top-level argument. |
| Error: Attributes of different cardinality (''{0}'', ''{1}'') cannot be mapped into arguments of the same cardinality (''{2}'', ''{3}'') within the same top-level argument. |
| Error: Repeating argument ''{0}'' cannot be mapped to a personalization key unless an element of argument ''{1}'' is mapped to an attribute. |
