How to find relation in parameters pairs in one variable

[#1]

Hi 

I have a table with a failure list. 

Each row has a systems ID and parts failed number 

 I would like to test if there are pairs of parts (or pairs). This means if there are pairs of parts in a system that fails together. 

If the parts fail together it will be shown by two different rows.

It is not clear exactly what you want, but try this: select Table > Summary. Select system ID and click Group. Click OK. You should get a summary table that is linked to the original table. A new column indicates how many rows in the original table are included in each row of the summary. Any summary row for system ID with N Rows > 1 has more than one part failure.
