Typically responds to a stronger resubmission.Both grounds are about what the file showed, not who you are.
Common refusal grounds
Why Schengen visas get refused
Pick the ground on your letter.
Purpose of stay
Most common
The officer could not see why this trip, on these dates, needed to happen.
Usually caused by
A cover letter that could describe any holiday
An itinerary the hotel bookings do not match
Eleven nights planned, four nights booked
Sufficient funds
The balance did not read as genuinely yours and available for this trip.
Usually caused by
A large credit landing days before you applied
Three months of statements instead of six
A sponsor with no proof of the relationship
Ties to home country
Nothing in the file showed what brings you back.
Usually caused by
An employment letter with no approved leave
No property, dependants or business documents
A first application with no travel history behind it
Travel insurance
Most fixable
The policy fell short of the cover the visa requires.
Usually caused by
Cover ending on the return date rather than after it
A limit below the required minimum
A policy naming one country instead of the Schengen area
Reliability of the file
Two documents in your file told different stories.
Usually caused by
Leave dates that do not match the itinerary
A job title the salary slips do not support
A booking cancelled before the interview
The decision that matters
Appeal or reapply. They are not the same thing.
An appeal argues the consulate got it wrong. A fresh application accepts the finding and answers it with a better file. Most refusals call for the second, and choosing the first can cost months you did not have to spend.
Time since the decisionAppeal windows are short and run from the date on the letter.
Deciding countryEach member state runs its own appeal procedure.
The ground they tickedDocumentary means something was missing. Discretionary means they weighed it and were not persuaded.
Where this usually points
Reapply with a rebuilt file
A documentary ground says something was missing, not that the officer misjudged you. An appeal argues judgement, so it has nothing to work with.
The fix is evidence: the document that was absent, or the one that contradicted another. That belongs in a fresh application.
You are inside the appeal window, so nothing is lost by preparing the new file first and keeping the option open.

A general guide, not advice on your file. An advisor reads the actual letter before anything is decided.
