Hi social_skillebe4,

To add signature fields to your PDF form, please follow these steps:

Open the PDF form in Acrobat.
Go to “All tools” and select “Prepare a form”
Make sure not to check the box that says, “This document requires signatures.”

Click on the Create form button.
In the left pane, under Add Form Components, select Digital Signature.

Additionally, it would be helpful if you could provide more details about the workflow you have in mind for the PDF, such as:

What type of signatures and properties you are looking?
How you plan to send the document.

This information will assist us in providing you with the most accurate guidance.

If you have any questions or need further assistance, feel free to reach out.

Thanks,

Meenakshi

Hi Meenakshi,

As you suggested, name has been changed but it is not taking as signature field in SAP SuccessFactors.

I could able to see General, Appearance, Position and Options only. Once I right click on the field, I am able to see rename. Once reemove the special charactors, Signature field is converting to Text Field.

I need Signature field without special charectors in that field name.

Thank you.

Hi social_skillebe4,

Thank you for reaching out and sharing the information.

It looks like you are using an Acrobat Sign form, and this behavior is by design.

If you are simply trying to create a PDF form with a signature field, please follow the steps below:

Click on the three dots next to the “Prepare a form” title in the tool pane on the left.
Select "Remove signing options."
Now, try to add the signature field again and see if that works.

For more information on creating a PDF form, refer to the following help document: Convert documents to PDF forms.

Let us know if this helps!

Thanks,

Meenakshi
