MRP Logic -Negative Available quantity in MD04

Hi Experts,
We have negative available quantity in MD04. There are no receipts generated particularly for some period even after MRP Run.
MRP Type is maintained as P1- MRP Fixing type.
Safety time is maintained as 3 days.
Planning strategy is 40.
Please suggest, what would be the reason, why i am not getting schedule lines between 09-Aug and 27-Aug which makes available quantity minus, after that there are generation of schedule lines.
Please help with inputs..

Hi,
MRP type P1 is used with planning time fence(mandatory).
Have you used pl time fence. How many days? For those period system will not generate any more planned order.

Negative Available quantity in MD04

Hi Experts,

Please suggest.

Hi,
Check the MRP type in material master. If this is ND, then system will not make any procurement proposal. Also check the strategies such Make to stock / make to order. If the requirement strategy & the strategy in the material master differs, then also there will not be any procurement proposal.

MD04 - Available quantity

Hi....
I m creating a Report to display the available quantity for a
particular material on a particular date....same way it is displayed
in the standard tcode MD04.
Also I need to display the projected usage quantity for next three
months where user will input the date. I need to find this projected
usage quantity again like MD04 transaction code. This tcode uses
structures MDEZ and MDSU to display the available quantity and other
data.
Are there any function modules availble to get it or are there any
tables from where i can get this required data?
Thanks in advance,
Prasad

Maybe you could use the function module MD_STOCK_REQUIREMENTS_LIST_API?

Hi,
I'm not sure what you mean when you are speaking about inventory levels and available quantity.
I mean that you may have stock of 100 pcs of a certain material but from an open PrdOrd can come a reservation for this component (e.g. 20 pcs) that reduces this the available quantity (to 80 pcs).
If you want only the stock levels, you don't have to write any ABAP code, since MB52 report is designed for this purpose.
If you want to know the available stock (considering requirements (PIR, DepReq, SO), and stock-like MRP elements (PldOrd, PurReq, PrdOrd, PO, etc)) you should check report MD04 and examine how it works, which tables it uses (ST01).

Is there a possibility should not consider available quantity at time of MR

Sir,
Is there a possibility should not consider available quantity at time of MRP planning?
Example:
Available stock: 100
Planning stock: 100 (MD61)
Schedule line to be generate: 100 Qty (Exclude the available quantity at time of MRP planning)
regards,
sampath

Dear Sampath/Raj,
1) Move the stock to particular storage location for which you don't want to be consider by MRP
2) Now go to OMIR t-code, input value as 1 for that particular storage location
3) Go to MMSC, input value as 1 for that particular storage location
4) Go to MRP - 4 view Down you can find field Storage location input value as 1
5) Now run MRP, system will not consider stock of that particular storage location

Available quantity

Hi,
The calculation for Available Quantity is sometimes confusing for certain companies. In SAP, Available=InStock-Committed+Ordered. Several companies consider Available as InStock-Committed.
It would be great if this calculation could be user-definable (per company). For example, you could have this under Document Settings, with the options:
Available=InStock-Committed+Ordered
Or
Available=InStock-Committed
Thanks,
Jose

Hi Jose......
I think you are not aware about MRP Functionality not only in SAP but in Basics also....

I have already config batch detemination. This material don't have MRP View 1-4 but I choose availibility check 01 in sales/plant view.
I check config at t-code OMCP and click transaction button to view good withdrawal (MB1A). The checking rules is 03 and I click define checking rule button to view availibility check control overview, double click availibility 01 and checking rule 03.
It sets as follows;
Incl Purchase Order
Include Reservation
Include Sales Requirement
Include Delivery

PS Budget Report S_ALR_87013558 shows negative available amount

Hi ,
We activated Availability control in our Project System. We created a project, WBS elements, network activities. Then setup the budget (WBS level) then release the budget. Purchase requisitions were made to PO items, some were receipted and some are still in Commitment. We also added the cost for Travel and Accomodation but haven't posted any actual cost for these network activities. Then when I generated S_ALR_87013558 the budget available amount shows a negative balance.
I already run CJEN to reconstruct the table, CJBN to recontruct the availability control balance but it still generating the same negative available balance.
We setup our tolerance limit to raise an error once the budget reached 100% but in this case it should already been triggered before reaching zero but it didn't happen.
Any solution for the problem is greatly appreciated.
From this going forward any cost that need to be added to the project triggers the error message BUDGET EXCEEDED! it supposed to been triggered before the negative available amount on the report was reached.
The report show that I have an amount presented on the following columns:
ACTUAL
COMMITMENT
REMORDPLAN
ASSIGNED
I already checked the individual network activities to checked if the balance showed in the RemOrdPlan is correct using the formula REMORDPLN = MAX(0, PLAN - (Actual+Commitment)) and it is consistent with the amount presented in the report.
thanks
sunil

Hi,
Some ideas :
1st. Try to check the history when the AVAC activated. It could be AVAC activated after PR/PO created.
2nd. Try run cj31. Compare the value there with the report S_alr_**** . If the value is not match , you should apply some notes. It could be your AVAC not working properly.
3rd. In order to prevent any futher issue for another project. Try to CJBW, CJEN and CJBN, for all projects (one time only). Put some budget on it. Next step do background schedule (CJEN after that CJBN) let say for weekly for all projects.
Hope can give you some ideas.
Cheers,
Nies

WM create TO: Available quantity in bin is zero

Dear Gurus,
I've got this error "Available quantity in bin is zero". Below is the step that I've done:
1. MIGO to issue 5PC in batch 1 to cost center.
2. In WM, stock now is in interim stype 911, qty -5 PC.
3. Then I created TO to transfer from the real bin (BIN1) to interim area 911 --> System has error "Available quantity in bin is zero".
4. I have double checked stock in WM (LX02, LS26,...), there is enough available stock in the BIN1, batch 1. Also there is no pending TR, TO.
Please help to find the reason of this error and how I can clear this interim area.
Thanks,
Trang

Hi Nick,
After I did step 1, material document created and also TR created. I see this TR works normal like other TRs.
But when I did step 3, create TO from material doc (LT06) or from the TR (LT04) with source bin is the real bin (such as Bin1) and destination bin is the auto interim bin named cost center (such as stype 911, Bin ADMIN), the system says that Bin1 has Available zero stock.
What I've checked is:
- I checked stock in IM (MB5B), stock is there. Stock in WM (LX02) also there in bin1.
- I tried to do transfer order for other batches of the same material in the same bin1, everything goes ok. The error only happens with this specific batch 1! When I check batch master for batch1, I couldn't find any thing strange there.
I still stuck with this error up to now. Please help!

Internal Orders (Negative Available )

Hello,
Anybody knows how is posible that the available of an internal order is negative? What´s more we have activate Availability Control.
Is it a system error?
Thank you very much in advance.
Patricia Guevara.

Hello,
Thank you very much ibn advance. I do´not require anything. We are in PSA and because of the year change we have observed that in 2008 my client has negative available in the internal orders (because of the goods receipts in 2008) and we do not know how because the budget is zero.
Because of that it´s available is negative, and we do not know how this have ocurred if the Availability Control is activate.
The normal situation is that when my client wants to receipt a purchase order the system issues an error because there is not budget in 2008 (It is yet zero).
Do you understand me?
Is it a system error? I think so.
Thank you very much in advance.
