As has been pointed out, the phrase is really a "bilan" of the "acquisition des documents".

"Acquisition" is another (like yesterday's "reprise") generic term, you can use the same word in English, it basically refers to the system successfully "acquiring", i.e. being able to store/use, the data. Again, you could use "take-on" or even, if you think acquisition may be vague, "(conversion and) storage", or "database population". Now you now what it means, pick a term that best suits your context :-)

"Bilan" is yet again very general - it could be a report/statement, if it's a physical piece of paper or a file reporting on database activity - how many records were loaded, now many failed to load for some reason (e.g. digitisation failure/incomplete). It could also just be a meeting where they talk about the success or otherwise of the project, in which case "assessment" or "evaluation" might fit, or even "review".

With the info available, "document acquisition report" is my best fit for now, but is not necessarily best in the fuller context.
