Behaviour parallel sequence in order production

[Former Member]

Hi gurus,

I don't understand behaviour of parallel sequence of operations in order production. Quantity of material flow should be sum of confirmated quantities in both parallel operations. For example,

Operation 1 flow of 100 qty

Operation 2 flow of 60 qty Operation 3 flow of 40 qty

Ops 2 and 3 are in parallel sequence, the sum of op2 and op3 is 100, operations should be final confirmed, but system needs op2 and op3 confirms 100 qty both. What is the functionality of parallel sequence, it's a poor behaviour!

Any idea?? I will reward points all answer!!

Thank you!

Hi

Parallel sequence is used in case two operations are run in parallel.say 0020 and 0030 are running in parallel.Meaning is 0030 can run independently (without depending on opn 0020).Now if qty is 100, then qty to be confirmed for both 0020 and 0030 should be 100 only.

Hi Daniel,

Parreral processing means this kind operatons may confirm without any relation conditions.And I think you have misunderstood this functionality.The rule you want is for Partial confirmations means Sum of all the partial confirmations of one Operation should be total operation qty.

"The rule you want is for Partial confirmations means Sum of all the partial confirmations of one Operation should be total operation qty."

-- Not, Sum of confirmated quatinties of op2 and op3 should be total operation, 60 + 40 is 100. In my production process, 40 pieces goes for op2 and 60 goes for op3. Total = 100 qty. System should indicate confirmation final not partial.

Main problem isn't confirmation of quantities else it's standar costs of order production. If system believes that in op2 and op3 (parallel operations) the flow is 100 qty both when you calculates costs system takes in account op2 and op3 at 100%. This fact provokes desviations with real time. Really op2 and op3 uses 40% and 60% of time and costs respectively

Hi Danial,

Once again I like to say is the thing which you belive is not possible or it is not there in standard SAP.

The relation between two operation which are parrrally processed is just for the Time not quanity.

If those operations are defined as parrerally processed then any of the operation can start first.

But if you want to set this kind of relation then you can do it via Material Quanity calculation.But I don't whether this function is available for Routing or not.

And Other option is use User Exit.

- CONFPP05 PP order confirmation.: Customer enhancements during saving

- CONFPP01, PP order confirmation: Determine customer-specific default values

- CONFPP04 PP order confirmation: Customer-specific input checks

Here you can set certain rule regarding your Requirement.

Hello Daniel,

Have you maintained any relationship FS,SS, FF or SF between two operation?

If Operation one will relate to Operation 2 and 3 then this type of proble m you will face.

Better that you dont maintain any Predecssor relationship for Operation2 and Operation3 in Master Recipe / Routing.

Hi Daniel,

In OPK4 check the following

Operation sequence = Operation sequence not checked....then do confirmation

you make it as operation sequence checked option and save and do the transaction it will work as required by you
