to avoid this behavior, you can enable the "Avoid Blank Record" property present in the Properties View of the Create Operation. In this way, the component avoids the creation of blank records in the case all the provided inputs are NULLs or empty strings.
Also, when the "Avoid Blank Records" option is enabled, the "Blank Attributes" property is enabled as a result. If no attribute is chosen in this property to perform the control, by default are controlled all the attributes of the entity. So, if the Create Operation receives at least one value, the record is consequently saved.
