Removing duplicate information in reports

Whenever I run a report collating information from various tables within my database, it repeats the information from each table at least twice (16 times in one case!). If I select "Hide Duplicates", it doesn't differentiate sufficiently - it gets rid of ALL duplicates in a certain field, even if it shouldn't, for example, if different expenses occurred on the same date, the report will show the date for only one of the expenses. How do I only get rid of the true duplicate records (or how can I run the report correctly so that it doesn't duplicate everything in the first place?)

RE: Removing duplicate information in reports

Hi Nicola,

Thank you for your question.

I would advise you first to take a copy of the database before trying the following to ensure you achieve the desired result first.

Are the tables related together?

Can the duplicated records be deleted from the relevant table?

There is a query you could run on the copy of the database:

1. Go to the Queries object and click the New button. Choose Find Duplicates Query Wizard and select the table or tables that contain duplicate records. This query will then identify any duplicates which could be then copied into another table or deleted. Make sure you add a unique field into the query to uniquely identify each duplicate.

I hope this helps.

Regards

Simon

RE: Removing duplicate information in reports

The tables are related together, but the duplicated records do not appear as duplicates in the original tables (apart from having particular fields in common), just in the report.

To be specific, it is a property management database and I have separate tables for (among other things) expenses, rental payments and management fees. I am trying to run a report that will show monthly rent minus expenses and management fees for each property.

I pull the information together for a particular property belonging to a particular landlord so obviously these two fields are shared by ALL the relevant records, but I "step" them so they only show once on the report. The problem is with entries showing what was paid and on what date.

For example, there should be 1 rent payment, 2 fee payments and 8 expenses showing for a particular landlord's property. Somehow I end up with 16 of everything in the report - 2 copies of each expense, 8 copies of each fee payment, and 16 copies of the rent payment.

I don't know why this is happening, so I don't know how to fix it.

RE: Removing duplicate information in reports

Hi Nicola,

Thank you for your response.

Can you tell me whether you have the Landlord field in every table or is there a separate table for the landlords details.

Perhaps you could try and create a query that collates all the information and then base the report on the query.

It is difficult to identify the problem without seeing the database. Unfortunately this would be beyond the scope of the forum as the amount of time spent looking at the database would exceed the allotted time allowed for each question.

Access tip:

Hiding Multiple Table columns

If you want to hide non-adjacent Access table columns. In Datasheet view, open the table that contains the columns you want to hide.

On the Format menu, click Unhide Columns.
In the Unhide Columns dialog box, clear the check box next to the name of each column you want to hide.
Click Close.

This method makes having to use the Hide Columns command repeatedly unnecessary
