Sufficient audit evidence refers to the quantity of evidence. The sufficiency depends on the professional judgment of the audit whether the evidence obtained for the selected item is enough. Another factor that decides the sufficiency of the evidence is the materiality of the item, the higher the materiality of the item higher will be quantity of audit evidence.
Appropriateness of audit evidence refers to the quality of evidence, that is relevance and reliability of evidence. It depends on several factors like the source of information, prepared by auditee or auditor, obtained from auditee or third party etc.
Sufficiency and appropriateness of audit evidence are related to each other, the requirement for more evidence reduces as the quality of the evidence improves or vice versa. Therefore, we can say that the Sufficiency and Appropriateness of audit evidence are inversely related to each other.

Tracing examines a financial document and follows its trail to the financial accounts. Vouching works the other way around. The process of vouching begins with a figure on a financial statement, followed by the discovery of the original document that supports that number. The importance of direction in comprehending these concepts cannot be overstated.
It's also critical to understand what these methods are attempting to establish. The evidence of completeness is provided through tracing while evidence of occurrence is provided through vouching. It's easy to become confused. There are components of that financial statement we haven't looked at, tracing from a document to the financial statement shows us completeness but not an occurrence. There may be only one document that we were able to track down. In the other direction, we discover the polar opposite. Vouching provides evidence of occurrence but not of completeness. This is because we might be missing an original document that was never included in the financial statement number, to begin with.
