How do I update Inventory in Access

I have a form where the user enters the item purchased and the quantity - I want that quantity entered in the customer invoice to be deducted from the Quantity_On_Hand field in the Inventory table. What would be the best way to accomplish this? I assume I would need to enter an expression in the after update on the quantity in the customer invoice? What I have tried so far has accomplished nothing but errors

Count Distinct in Access
I'm trying to do a select count distinct values for a table. Reading a few sites on google, I know that access does not support this. The database is for a library inventory system. I have 2 tables: Book_Copy and Inventory. Book_Copy has the columns (Copy_ID, Book_ID Checkout Date, Check In Date and Due Date, Status). The inventory table has columns: Inventory ID, Book _ID and Available Copies. I am trying to update the Inventory table, Available copies column based on the status (checked in) in the Book_Copy table. I have tried to write an update query trying different ways but all I end up getting is syntax errors. Any help would be appreciated. This is what I have tried:
UPDATE Inventory
SET Inventory.Available_Copies = (SELECT COUNT (*) AS Count from (Select DISTINCT BOOK_ID from BOOK_COPY where Book_Copy.Status_abbrv = 'CI');

Accessing my inventory remotely
I have a simple Inventory application (developed using Access 2000) which is stand alone. That is the changes to the inventory can be done only on a single PC.
Now, I need to make it available from different geographical locations i.e. via internet. However, it will be accessed from one location/one user at a time. My inventory application requires Access 2000 to run.
Is there any way that I can upload Access 2000, my inventory application and associated folders to a remote 24/7 Server and access it at will. What is the simplest way to do this

retail and wholsale in a ms access 2007 database
please is it possible to have a store inventory, retail inventory ,wholesale inventory separately in ms access database?
the sale point will be one it will just reflect where the item is coming from.
for example someone comes to buy from wholesale, it deducts from the inventory in wholesale, if the person comes to buy from retail it deducts from the inventory in retail
at the end of the year if we want the stock taking, it does the individual inventory and totals all the inventory together
would be glad if any help is rendered

Inventory Form that adds/subtracts from current inventory number in table
I am currently trying to create an inventory database that includes a form that will update the inventory numbers last updated in the database. Rather than having one row constantly being updated in the table, I would like to keep track of what has come in and out of the warehouse and when.

So far, I have the fields on my form and am able to update the next record by entering in numbers, but I'm not sure how to use what I enter into the fields (based on a dropdown of inbound/outbound) to either subtract from or add to the last updated record in the table.

How to make an Update Query
I'm trying to create an update query. I have an inventory table that contains the type of inventory. One of my inventory types is "Copy Machine". I want to create an update query that changes "Copy Machine" to "Copier", but I am really struggling

Update Record using Combo Box To Navigate
I currently have a table with three fields (Brand, Service, Inventory).

Brand is a primary key, it can only show in the table once. However, I'll need users to go into the table and update the service and inventory numbers every month.

What I envision is a form in which Brand is a combo box, the user can pick their brands and then the Service and Inventory fields change to whatever in in the table currently. The userscan then update those values, hit a button, and the changes are stored in the table.

I've already tried doing this and what happens is on the first record, I try changing the brand, and the first records brand changes to the one I picked and it is saved in the table (like Ineed to make brand a locked field).

Running an inventory query
My job is using Access 2003. I want to be able to take a weekly inventory of products. I figured out how to use a query to print a list of products that should be reordered based upon minimum sotkc level - current level = reorder quantity. I am trying to figure out how to track the usage of a product. Can I make that query note the current date and inventory level and update some table each time. So I could look at an item and see each week how many of that item was ordered?

Simple Inventory
I'm trying to use a query to show my current inventory. I produce chili and have ingredients and when ever I use an ingredient I would like it to be removed from my inventory and whatever I created will be added to my inventory or query.

Subtract from inventory
I have a table (tblInventory) with a quantity field (Qty). I am trying to subtract the quantity that the user enters on the transaction form (frmXaction) as removing from inventory, from the quantity in the inventory table. When that is done, I want the transaction form to close, then the Inventory detailed form (frmInventoryDetail) to close, and then requery the inventory (frmInventory) to show the new quantity in the inventory. I copied the code from another post & put in my names. I must have missed something, because now I get a runtime error 3144: Syntax error in update statement. It looks just like the code as far as I can see. Does anyone else see a problem with this code doing what I want it to do?

Private Sub CmdConfirm_Click()
Dim var As Long
var = DLookup("Qty", "tblInventory", "[Indx] = " & Me.txIndx) - Me.Qty

CurrentDb.Execute "UPDATE table SET " & _
"tblInventory.Qty = " & var & " WHERE " & _
"[Indx] = " & Me.txIndx

Access Well Customized Inventory management Database

I need someone to program an automatic inventory system to with with my ecommerce webstore and other selling locations.

Inventory: add/remove stock qty from table
I hope someone can help me - I haven't touched Access in years and I have been "volunteered" by my employer to write a basic inventory system. I am using Pendragon forms along with the now obsolete Handspring Visor equipped with scanner to scan barcodes and collect data.

What I can't seem to wrap my head around is performing a record lookup from the scanned data (I have a table with scanned data to add to inventory (tblAddInventory), a table with scanned data to remove from inventory (tblRemoveInventory) and a master table with all ofmy warehouse inventory (tblWarehouseMain) and performing a calculation on the records to add - or subtract - stock, depending on what table the data comes from.

I am (er, rather used to be) comfortable with VB.

I have tried to create an update query as well as some basic code via control on a form, but I'm finding myself at a loss. Anyone willing to take a shot at helping or pointing me in the right direction?

tracking and receiving inventory in multiple locations
Heres what I need:
The company I work for has inventory at our physical location (our shop) and we also have inventory on trucks. I need to track the inventory in the shop and trucks so that when items get below a certain preset level I can run a report to find out how many of each part I need in each location.

Create purchase orders and receive the inventory to whichever location I need it at. I would like to at some point be able to track where the parts are going.

Inventory System
Anyway, I've decided to begin reworking my company's database (which is an ENORMOUS task) and have run into a few hangups. The first of these hangups is the inventory system.

I'm trying to figure out the best way to set up the table(s) for our inventory. Currently, there are two "main" types of inventory item: Glass and Non-glass.

The Glass inventory items are stored based on the following characteristics (which are ONLY used for glass inventory items):

* Height (number, ##0.000)
* Width (number, ##0.000)
* Color (number, integer ID field connected to a "colors" table)
* Light Transmission/Transparency (number, #0%)
* Thickness (number, 0.000)

My question is this: Do I use separate tables for the Glass inventory and the Non-glass inventory? Or should I combine the two and just leave a bunch of null fields for the non-glassinventory items? There are about 100 different glass items in our current inventory and about 400 non-glass inventory items.

Inventory Database, Local Network Only
I am working with a company and want to get into making database's and inventory list but I want to be able to automate it. this is what I am looking to do:

1. Setup deposit ( This is where everything gets entered if they get shipment of new items and automatic adds to inventory database )
2. Inventory database ( this is where all items are stored and organized, with pictures of items and add to invoice type feature )
3. Invoice ( this is where items are placed when they are sold and are removed from inventory database )

Thank you guys for your help and this place looks great for me to startthank you.

Inventory control database
I just started to work in this new company in Saudi Arabia and the need someone to control inventory. Our company receives Materials from one supplier and distribute to around 20 subcontractors.

I need an inventory program or some help how to use access to accomplish that. I need to track how much materials received andhow many given away to each subcontractor and how much left and so on.

To index or not to index
I have a table of stuff stored in a repository and an attached table of inventory dates, linked one-to-many by an Autonumber ID field. I regularly need to find the oldest or newest inventory dates (or all, in order by date) for each item record in the inventory table, which is normally an automatic case for indexing. But this stuff is not inventoried very often, so far, only two out of over 80,000 records have three records in the inventory table, all others have zero, one or two inventory records. This is NOT going to change. It will likely be decades before there are as many as ten inventory records for any item record, and then it will not be for very many. I doubt if this database will live to see the day, although I'm trying to make it as useful and robust as I can.

Extract old part number data from an access inventory database
Trying to extract old part number data from an access inventory database. I need to find records where the on hand, on order, on backorder for a part number are all zero. the problem is that this database also has a field for branches, so I want to pull records only where none of the branches have inventory.

so that if one branch still has inventory I don't want thatrecord returned.

what I was using was
select branch, partnumber, [on hd], [on or],[on bo] from inventory where [on hd]=0 and [on or]=0 and [on bo]=0

which obviously gives me results dead partsbut does not filter out part numbers that may still be active at some branches. I cannot figure out how to filter that. Would a recursive select be best or use union?

Update Inventory in Subform
What I would like to do is Choose an "assembly" from a combobox and have the subform open up the list of instruments in the assembly.
Then have 2 textboxes below with "QtyUsed" & "QtyReceived" and a button for "update inventory".

On click event for the button it will update QtyOnHand in list of subform.

Something like "QtyOnHand = QtyOnHand - QtyUsed + QtyReceived"

Can this be done? I have tried several ways but not quite getting it.

Do you make the subform a combobox so when you choose a record it has focus? Or is their a way to show the whole list of records (datasheet view) and still be able to update particular record with buttons below
