ACCESS FEED: Re: [MS_AccessPros] Inventory Aging

Doyce,

Sorry about messing up your name. I need more coffee.

I would try move the Nz() to address only the DSum()

Nz(DSum("tnxqty_15","Transaction History","PrtNum_15='" & [PartID] & "' and TNXCDE_15 = 'R' and MAXID > '" & [MAXID] & "'"),0)-[onhand_01] AS LeftSum

Hi Duane,

I'm not Art, I'm Doyce but your description is correct. Here is some sample data:

**qryInvAgingSelect**
MAXID	PartID	TDate	COST_01	TNXQTY_15	RunTotal	onhand_01	D	LeftSum	AgeQty
2792852	1001004	9/28/2016	12.6	1	1	3	-1	0	1
2248382	1001004	7/23/2014	12.6	3	5	3	-1	-1	1
2248716	1001004	7/23/2014	12.6	1	2	3	-1	-2	1
2248386	1001011	7/23/2014	2.7	8	9	7	-1	-6	6
2248723	1001011	7/23/2014	2.7	1	1	7	-1	0	1
2248387	1001012	7/23/2014	2.7	8	9	7	-1	-6	6
2248724	1001012	7/23/2014	2.7	1	1	7	-1	0	1
2785852	1001017	9/13/2016	10.8	2	2	1	-1	0	0
2785854	1001020	9/13/2016	24.05	2	2	1	-1	0	0
2785909	1001022	9/13/2016	2.25	4	4	2	-1	0	0
2785910	1001024	9/13/2016	1.5	2	2	1	-1	0	0

I have already created a report based on this query that puts the amounts in the correct aging buckets. If you notice in the data above, the parts that have more than one receipt, the AgeQty and LeftSum calculations are correct. However, if a part has only been received one time, the LeftSum and AgeQty calculations return zero. This is because of the NZ function in the formula. If I remove that from the formula, the calculation returns a null. I'm thinking there is a better way to calculate the LeftSum. If I can get that fixed, I think the AgeQty will calculate correctly. Here is the SQL for the query:

SELECT [Transaction History].MAXID, [Transaction History].PRTNUM_15 AS PartID, [Transaction History].TNXDTE_15 AS TDate, [Part Master].COST_01, [Transaction History].TNXQTY_15, DSum("tnxqty_15","Transaction History","PrtNum_15='" & [PartID] & "'and TNXCDE_15 = '" & "R" & "' and MAXID >= '" & [MAXID] & "'") AS RunTotal, [Part Master].onhand_01, IIf(Nz((Nz((DSum("tnxqty_15","Transaction History","PrtNum_15='" & [PartID] & "' and TNXCDE_15 = '" & "R" & "' and MAXID > '" & [MaxID] & "'")-[onhand_01]),0)),0)<=0,True,False) AS D, Nz((DSum("tnxqty_15","Transaction History","PrtNum_15='" & [PartID] & "' and TNXCDE_15 = '" & "R" & "' and MAXID > '" & [MAXID] & "'")-[onhand_01]),0) AS LeftSum, IIf([RunTotal]<[Onhand_01],[TNXQTY_15],Abs((Nz((DSum("tnxqty_15","Transaction History","PrtNum_15='" & [PartID] & "' and TNXCDE_15 = '" & "R" & "' and MAXID > '" & [MaxID] & "'")-[onhand_01]),0)))) AS AgeQty
FROM [Part Master] INNER JOIN [Transaction History] ON [Part Master].PRTNUM_01 = [Transaction History].PRTNUM_15
WHERE ((([Transaction History].TNXCDE_15)="R") AND (([Part Master].onhand_01)>0))
ORDER BY [Transaction History].PRTNUM_15, [Transaction History].TNXDTE_15 DESC;

Hi Art,

I believe you want to start with the number on hand (current inventory) and step backwards chronologically to see when you can account for purchasing a specific quantity and the price paid. The purchase date will identify the bucket the quantity and price go into. When all of the number on hand have been accounted for you are done putting prices and quantities into buckets.

Do you have some sample records and how you would want these reported?

Thanks,

Duane

Hi Rob,

No, that's not quite it. I need to know how long my inventory has been here.. If I have a part with more than one receipt, I need it divided by receipt date. Example part A has 50 on hand. I received 20 in May and 10 in July and 20 in August. I need to know that if Part A cost $1 that I have $20 of current inventory, $10 of 60 day inventory and $20 of 90 day inventory.

Thanks for taking time to answer.

Hi Doyce,

If I understand right, your issue is whether what you still have on stock was purchased for the last time.

So you need a query that gives the last receiving date of items with OnHand_01 <> 0. That's a simple join on the two tables.

Next you use that query in a query that groups on month of the last purchased date. Unless I misunderstand what info is needed, that would do the job I think.

A couple suggestions:

Every time I read about a specification for "buckets" I create a table of "buckets" with MinBucketValue, MaxBucketValue, and BucketTitle.

Is MAXID numeric? You are using a numeric operator ">=" and yet comparing it with a string.

You are calculating LeftSum in the query and also using LeftSum in other expression. I never do this. I would repeat the LeftSum expression/calculation in place of using LeftSum elsewhere.

You do the same thing with SeqID. Why not use [Transaction History].MAXID?

I would always make sure there is a space prior to the "and". You have ..."'and TNXCDE_15....

This might or might not resolve your issue but I would sleep better.

Hello Pros,

I have been ask to come up with a way to "age" our inventory into buckets based on receipt date using FIFO. "Current" inventory has been received in the last 29 days. Inventory received between 30 and 59 days ago would go into the "30 day" bucket and etc. I have approached doing this by going through the receipt transactions in our Transaction History table in descending date order and comparing the transaction Qty to the onhand qty. The following SQL is almost getting me what I want. It works fine as long as there are more than 1 receipt for a part. If it is a part that has been purchased and received only once, the AgeQty calculation fails and returns 0. Here are the fields in the query and a brief description of each:

SeqID is an alias for MaxID which is the primary key in the transaction history table. It is autonumber.

TDate - Transaction Date (Receipt Date)

TNXCDE_15 - Transaction Code. "R" is an inventory receipt

Cost_01 - The cost of the part. Used to value the inventory.

TNXQTY_15 - The quantity of the part being received.

RunTotal - The sum of the parts received starting with the most recent receipt in descending date order

Onhand_01 - The total number of parts we currently have onhand

D - a Boolean as to whether this receipt should be included in the aging.

LeftSum - How many are left to allocate

AgeQty - how many are in this age bucket.

Part Master is the table with the parts records

Transaction History is the table with the receipt records.

Here is the SQL for the query:

SELECT [Transaction History].MAXID AS SeqID, [Transaction History].PRTNUM_15 AS PartID, [Part Master].PMDES1_01, [Transaction History].TNXDTE_15 AS TDate, [Transaction History].TNXCDE_15, [Part Master].COST_01, [Transaction History].TNXQTY_15, DSum("tnxqty_15","Transaction History","PrtNum_15='" & [PartID] & "'and TNXCDE_15 = '" & "R" & "' and MAXID >= '" & [SeqID] & "'") AS RunTotal, [Part Master].onhand_01, IIf(Nz([leftSum],0)<=0,True,False) AS D, Nz((DSum("tnxqty_15","Transaction History","PrtNum_15='" & [PartID] & "'and TNXCDE_15 = '" & "R" & "' and MAXID > '" & [SeqID] & "'")-[onhand_01]),0) AS LeftSum, IIf([RunTotal]<[Onhand_01],[TNXQTY_15],Abs([Leftsum])) AS AgeQty
FROM [Part Master] INNER JOIN [Transaction History] ON [Part Master].PRTNUM_01 = [Transaction History].PRTNUM_15
WHERE ((([Transaction History].TNXCDE_15)="R"))
ORDER BY [Transaction History].PRTNUM_15, [Transaction History].TNXDTE_15 DESC;

The query results all look good except for the LeftSum calculation and the AgeQty calculation and they are correct for all parts that have more than one receipt. If a part has only been received once, the calculations show zero.

How can I get this query to correctly age all receipts? Is this the best approach to my request? I adapted this approach from this post I found on Experts Exchange. https://www.experts-exchange.com/questions/27920676/Inventory-Aging.html
