The sentence
When a read asks for more rows than any read in Tightly may ask for, it is refused in the engine's own words and draws no figures:
limit must be an integer between 1 and 10000
In the workspace the sentence stands under How many, the control it is about. Anywhere else it reaches Ask Tightly, which says in its own words that the read was refused.
What it means
Every answer from Ask Tightly that draws a table or a chart is a read over one domain: sales, inventory, orders, suppliers and the rest. One ceiling applies to every domain alike. A read that names no row count returns 200 rows. A read that names up to 1,000 receives what it named; a read that names more than 1,000 receives 1,000, without a sentence to say so; a read that names more than 10,000 is refused in the sentence above rather than trimmed. The cap keeps an answer countable and a chart readable; it is not a count of what exists. Nothing was cut from your data.
How many, in the workspace, offers Top 10, Top 20, Top 50, Top 100 and Every row, so a choice made there never meets the refusal. Every row asks for no count, which means the engine's own 200. The refusal is met by a view that asks for a count of its own: a link that carries one, or a question that names one. When it lands, the change is not applied, the figures on screen stay the ones before it, and nothing was saved.
On Essentials, Essentials+ and Pro, Ask Tightly can also answer a question no chart read covers by reading your records its own way; such a read stops at 500 rows. Tightly Lite draws its ten fixed charts and has no read of that kind.
A refused read is not a failed read, which says so in its own sentence and shows no figures, and it is not a Snapshot, which is an answer whose data will not re-run.
What to do next
Ask for fewer rows and keep the grain: narrow the window, filter to the category or the channel you mean, or ask for the top rows and let the rest roll into one line. Read by on the chart coarsens the grain in one press, and How many takes the count back to one it offers. Where you need every row, go to the page that owns them rather than asking for them in an answer.
Who to ask
Ask Tightly answers from this article and can reshape the question for you: say what you want to see and it proposes the narrower read.
