Prevent an object creation or update when a certain condition is met to avoid errors in Salesforce and also to define the connector logic to match your process needs.
For instance, on a job application there is a "Yes" checkbox to include a resume. Once clicked, a file upload appears. The file upload will create a Resume object.
Use the Skip-If
Check the but skip this step if... box and enter a formula to make this object conditional.
If TRUE, this step, and any dependent step, will be skipped. Other non-dependent objects will still be processed.
If the formula returns FALSE, or no formula is specified, this object will be processed normally.
To base the condition on a form field value, use aliases, which are listed in a page linked at the bottom of the screen (Show the list of available aliases for this form).
For example, in the image above, the alias for the question is %%tfa_Upload%%. The condition is 'Skip if the upload field is empty'.
