I have a configuration table (named 'Usager actif') with 'Projet ID actif' and start/end date values (field name 'Bilan date début' and 'Bilan date fin') linked to a timesheet table (named 'FTemps lié Projet bilan') to show only the records that match, according to the following relation:
This table is also linked to a step table (named 'Étapes lié FTemps lié Projet bilan') to show a list of steps used by the timesheet table (named 'FTemps lié Projet bilan'), base on the following relation:
So the last table (named 'Étapes lié FTemps lié Projet bilan') is shown in a portal and it's working correctly (show only two steps used, for all the timesheet records). But I wanna show the total time used for each step (first step is 5 hours, and last one 95 hours). It's working correctly if the start/end date included all timesheet records. But if I shrink the ending date (removing 2 hours from the timesheet in step 2), the total time by step still show all time since the context does not follow from timesheet table to the step table in relation.
I still see 5 hours for step 1 and 95 hours for step 2 (should be 93). The total time for all step is now 98 hours, since the ending date has been shrink (removing 2 hours on step 2).
How can I do this (hope fully I'm clear enough)?
I am currently building a database to handle the inspection sheets used by our Quality lab. Here is the relationship layout:
For each revision on the Revisions table, I have a differing number of Dimensions that need to be measured (some parts/revs will have 5 dimensions, while others will have 15). Each dimension has a specified type of instrument used in measurement, and a max/min value. The instrument used is a drop down menu that references a list of instruments/gages that we use.
Here is how I have my inspection sheet currently laid out:
The portal on the left points towards my dimensions table. It shows the data corresponded to the specified Part Number and Revision level. The data contained in this portal is uneditable from this form. The portal on the right points towards my RecordedDimensions table. It will store data that will correspond back to the Lot# associated with that inspection sheet.
I also have a table that pairs all the different types of instruments we use, with their corresponding gage ID's:
Now I would like my user to be able to click on the dropdown box under Instrument#, and that drop down box will only show the Gage ID's for the specified gage. So, if on the dimensions table, a dimension calls out for Digital Micrometers to be used, then when my user goes to select the instrument ID (which is saved in the RecordedDimensions table) it will would allow them to choose 151, 152, 153, 306, 324, 330, and 331.
Please let me know if I have not provided enough information/pictures, I will gladly provide more.
Thank you in advance for any assistance you can offer me!
Hi...I have created a database using a "modified" anchor buoy method and so far everything works great...but...I have a portal in a "join table" that works fine...however, my button that is supposed to open the record in the portal row does not function...it returns nothing. The records are indeed related (see RG) as the fields show up from the related table without relational conflicts, but this button that is supposed to open the "library" table with the related record pulled up simply does nothing.
I have attached the DB. Also a screen shot of the table where the portal is (it is actually a join table layout, this may be the problem). I don't understand how the button (with the little arrow) does not go to the table that the actual portal record, which IS related because I see it show up on the portal row...what is not right here?
I am trying to set up a database to calculate and report exhaust emissions from diesel engines and am stumped at Step #1: The infamous Entity Relationship Diagram!
I am looking at a few thousand engines and need to calculate how much of what kind of pollutants they kick out into the air. I have spreadsheets that list the Year of Manufacture, the horsepower, the serial number, how long the engine ran during a given year and how much fuel it consumed during that year. I also have some spreadsheets that list what the Emission Factors, usually expressed in pounds per hour operated or pounds per gallon of fuel consumed, for each of the two dozen chemical compounds I’m interested in tracking.
Those emissions are relatively simple to calculate: Multiply the Emission Factor times the number of hours operated (or times the gallons of fuel consumed) and we’re done. Except for the fact that the Emission Factors are based on the Year of Manufacture and, in some cases, the horsepower rating of the engine, so I have to circle back around to the Engine table: I don’t know how to connect the emission factor for, say, Arsenic to a specific engine, say a 154 hp Chevy made in 2014, based on that engine’s year of manufacture and hp rating.
So my ERD keeps looking something like this: Engines --->Emission Factors--->Engines or Engines ---< Emissions >---Emission Factors--->Engines
My computer keeps puking ones and zeroes all over my keyboard when I try either setup in my Relationship Graph!
The only other way I can think of accomplishing these seemingly simple calculations is to write a boatload of scripts with variables, but I’m not even sure I could come up with all of the combinations/permutations involved. And, unfortunately, I can’ even spell SQL, let alone know how to execute one of ‘em!
I have attached a (simplified) copy of the spreadsheets I currently use to better explain my problem. I hope one of you will find this to be mind-numbingly simple and explain how it should be done. Thanks very much for your time and consideration.

Sorry I do not know the terminology of what I need.
I am trying to setup a database to record some info on postcodes. What I need to do is, each supplier can have 4 types of lead (back data, profile, survey, 2nd use). I have two tables for suppliers and postcodes already. I also have 2 join tables for many to many relationships. I need each field in the postcodes database to be able to store a count for each supplier's lead type.
Supplier - Lead Type - Postcode - Count
Supplier A - Back Data - AB - 20
- BB - 155
- CB - 30
Profile - AB - 55
- BB - 27
My problem is with the way I have set the relationships up currently. When I add a count for a postcode it adds that count for all suppliers. I need the postcode count to be specific to each supplier and lead type.
Can anyone tell me what I need to do to get this working correctly? I have attached a screenshot of my relationships.
