Click on signature field, you will get the pop up box as shown below.

If you want to check the signature properties then click on signature properties button.

If the signature is valid then you will get 'Signed and all signatures are valid' message appear at the top of the window.

Here we can also change the field entries even after the signature field has been filled. When saving the form after we modified the any of the field entries in the form, you will get the following message at the top ‘Signed and all signatures are valid, but with unsigned changes after the last signature’.

Click on signature panel at the top right side corner (Shown on above picture), there you can find the log as shown below.

When you click on highlighted statement under Form Fields Filled In, it would show the modified value of the field. And also you can check the value before modification in the Click to view this version under signature details.

Click on Next button.

Provide the required information and press Next button as shown below.

We get the following screen. It asks for password. Provide the password and press finish button.

We get the following screen.

After providing the password only you can able to sign in. Suppose if you press the sign button without giving password, it asks for password saying that ‘A password is required to use this digital ID’.

Now press the sign button. The signature would be appeared in signature field.

In the above two cases, we can able to change the field entries after the signature field is filled in the form. But, we can also have an option to avoid / restrict making changes to the content of the fields (‘Date’ in this case) once the signature field is filled.

Now go to library tab-àWeb Dynpro native. Drag and drop the signature-sign and lock to layout editor.
