The Attribute, parameter, and argument datatype validation rules table describes validation rules for Mobile Business Object (MBO) length, and precision and scale datatypes.
Type and Entity | Feature | Validation rules/Action |
---|---|---|
GUI: Attribute, parameter, or argument | Length |
Only specific datatypes (string, decimal, float, double, binary) support “Length”. The length of the parameter/attribute cannot be larger than its mapped-to argument/column. |
Model: Parameter or argument | Default value | The default value cannot exceed the size defined in its “Length.” The decimal default value cannot exceed the the “Precision” and “Scale” if defined. |
Model: Parameter or argument | Length/Precision | The ''Filter by'' parameter's maximum length must be the same as the "Fill from attribute's." Data length of the parameter cannot be shorter than that of the "Fill from attribute." |
Model: Device link | Length/Precision | The data length/precision of the target element cannot be shorter than that of the source. |
