MDVP Collective check

[former_member1190262]

Dear Experts

I am trying to execute the MDVP collectively.

I entered one part number ( A) and it has the component B and 2 planned orders

Stock of component B is 200 pcs

Requirement from each planned order is 400 pcs.

so in total 800 pcs are needed.

But on doing Availability check, the system gives that 50% of each planned order can be produced.

Ideally only one planned order of 50% can be produced and not 2. But the system is showing otherwise and marks the component B as Missing component.

i am using firm planned order too...

I am using customized checking rule which checks only physical stock. and Partial confirmation.

Am I missing something. Kindly guide.

thanks and regards

Nagendra,

Please determine the availability checking rule used by your planned orders (OPPJ).

Then, display the scope of check for this rule and the availability check in your material master (OPPJ).

Also, please display CO09 for material B using the checking rule configured for Planned orders.

Hi Dogboy 49,

thanks for the suggestions.

in OPPJ at the plant level we have the std. 02 and PP for scope of check and in MRP group I have mentioned ZB which considers only physical.

I checked via planned order and it is picking the correct combination maintained in MRP group.

The issue is the system is not doing a collective check instead it is doing one by one even though firming of planned order is set

this ZB is based on partial confirmation.

But in CO09 if I enter with ZB then the system doesn't show anything it is blank. even if I select with "reqmt qtys".

kindly advice

thanks

Nagendra,

The issue is the system is not doing a collective check instead it is doing one by one even though firming of planned order is set

Well, when the system does a collective check, it always does each check one-by-one.  This is normal.  'Firming' is irrelevant to ATP.  Firming is only used for planning, not for ATP.

During ATP, each requirement being checked 'competes' for any existing availability.  Availability is computed by including all the supplies and all the demands that you have placed in your scope of check.

Your problem seems to be that the system is not respecting the results of the checks for any other planned orders that have already been confirmed.  In order for ATP algorithm to 'know' that other planned orders have already been checked, and that they should reduce the ATP quantities for the CURRENT order being checked, you have to check "Incl. dependent reqs".  If you think you will also be converting these to production orders, you may also want to place either an 'X' or 'A' in "Incl.depend.reserv" as well.

CO09 shows only the supply and demand elements that are being checked in the ZB rule.  Since you are checking no other requirements, no requirements are displayed.  What is a bit puzzling is that you said there was 200 in stock of B; but your CO09 says zero.  Can you display an MMBE of B?

Hi Dogboy 49,

Please find the relevant screen shots

this is the availability check of one header material having 3 planned orders

the requirement for component B is "4 pc" to make "1 pc of header"

so total stock of component B needed is around 2400 pcs.

this the MMBE screen shot

stock available is only around 1600 pcs .. in the mean time i will try with changing the customization.

thanks

Nagendra,

????   So, now, stock is 1624 for 'B'?  I thought you originally said it was 200?

And CO09 for this material ('B') still shows zero?

Please don't change the scenario until I fully understand what is going on.

Hi,

Initially i gave that as an example to understand.. the screen shots are of real scenario.

but the issue is same..

the stock is less if we consider all 3 planned orders together but it will be ok for one planned order

Nagendra,

The thing that now makes no sense is that CO09 for 'B' shows zero stock, but MMBE for 'B' shows 1624.  I can't think of any ATP setting that will show zero stock in CO09 when there is 1624 of unrestricted on the shelf.

Hi Dogboy 49,

The issue is resolved now.

i have created a new check rule ZJ with the changes you have mentioned.

But added the reservation too. 

Pls find the CO09 screenshot

this is for a different product.

also the MDVP worked now.

Pls check those screen shot too. here the component required is 4 pcs for 1 pc of header material.

system confirmed for the first order 50 pcs fully. component requirement was 200 pcs and in the second case it confirmed 1 pc.

Thanks for the timely support...

thanks and regards

Nagendra,

I am pleased you feel that your issue is resolved.

Bear in mind the that 'reservations' checkbox you have selected is for 'MB21' type reservations.  If you wish to include the dependent reservations that are generated by production orders, then you need to select the other checkbox I indicated earlier.

Hi Dogboy 49,

thanks for the info. But we don't have any production orders for these types of materials.

Hi Dogboy 49

I have a different kind of issue here. the previous screenshots are from the test system and everything was working well.

the same customization is available in the production system too. but the behaviour is little different

MDVP - collective availability check

i took one part number to check. in the initial screen system showed committed qty as 58 pcs but when i went to the missing parts list it is showing like attached.

why is this behaviour.

i checked via planned order and it is showing correctly

what could be the reason for this?? also this checking is not getting saved. if i go out of the transaction all the check is lost.

the scope of check was already transported and system picking the same correctly

could you kindly advice.

thanks

Nagendra,

I am not sure now which part of this is distressing you.

....i took one part number to check. in the initial screen system showed committed qty as 58 pcs....

Yes.  And look at the commitment date.

You say you don't like the missing parts list.  Why?  Is there any question that there are missing parts for these components?

How would you like for it to behave?

Best Regards,

Hi Dogboy 49,

if you check in the availability check via planned order it gives the missing parts and confirms according to partial confirmation logic.

But in the collective check you cannot find that even though the system does the partial check. If I go the missing parts there is no info on which part is missing. it should come with a X.

thanks and regards
