Overview
Application Scenario
Sometimes, you may want to only submit modified data in the data entry template during submission to improve the performance. In this case, you can use No Update, No Modification. After No Modification, No Update is selected, if data is not modified, it will not be submitted.
For example, if you only modify the category ID of the third record, only this record will be updated after submission.
Function Entry
Choose Template (on the designer menu bar) > Data Entry Attribute, set Submission Type Selection to Smart Submission or Update Submission, and select No Modification, No Update (deselected by default). The No Modification, No Update function appears only when you select the above two submission methods.

Notes
Only Supporting Cell-Type Values
No Modification, No Update is only applicable to values with the type as Cell. If the types of values are String, Formula, Parameter, and so on, this function will be grayed out and unusable.

For example, if the value of Abort is false (string), the No Modification, No Update function cannot be selected.
Suppose you still want to select No Modification, No Update in the above-unsupported scenarios. In this case, you can enter the unsupported contents such as formulas and fixed strings into specific cells and then bind these cells in the data entry attribute, as shown in the following figure.
Alternatively, you can mark the modified/inserted/deleted rows and only submit the marked data rows through submission conditions.
