Minimum Send-Ahead Quantity (overlapping)

[former_member182449]

Dear APO Expert,

I maintain Minimum Send-Ahead Quantity in routing as 1 EA and Minimum queue time 12 Min

when i transfer routing to APO with CIF where i can find this value maintained??

I think it will be in PPM but i don't have R3 Linked to APO to test it

Appreciate your Help

Hi Rami,

Minimum queue time+minimum move time will come as process related minimum interval in PPM. I think processing time for minimum send ahead ahead quantity will be added to above times.

Dear Santosh,

Thanks for your help

I need to maintain it manually , i don't have R3 connected to APO

I have this scenario :-

Operation A

Operation B

Operation B be should start after 1 EA Minimum send ahead quantity , that's mean after 12 Min from starting of operation A , which maintain as Queue time in R3

Hi Rami,

You can maintain in PPM manually in definition of relationship between activities. Maintain start --start relationship between 10 and 20 with process related minimum interval as 12 min.

Dear Santosh,

This what i did exactly

I have work center start at 07:00:00 & End 15:00:00

Each operation with one activity P duration 8 H

I have this Result as we did like you say

Operation A Start Date 10.3.2011 14:59:59 and End date 11.03.2011 14:59:59

Operation B Start date 11.3.2011 07:00:00 and End Date 11.03.2011 15:00:00

Operation B 11.03.2011 07:12:00

Please advise

Hi,

Have you maintained start---start relationship between operation 10 and 2o along with maintaining process related time interval?

As results are not showing that?

Second which Scheduling strategy you have used for scheduling the order? As you need to consider order internal relationship in setting of strategy profile.

Dear Santosh,

I found that APO not consider time in Process-Related Minimum Interval if you work with planning direction Backword

in your strategy

it's works only with planning direction Forwards

Could you please correct me if i'm wrong , or let me what i need ?

Hi Rami,

1.What scheduling mode and submode you are using in scheduling strategy.

2. What is action in case of scheduling error set in scheduling strategy.

3. What results you are are getting scheduling direction backward?

4. Have you checked is there enough space for dependent operation to get scheduled at that point of time if you are working with find slot?

I mean just try to check whether there is some problem in schduling operation to required time?

Santosh

Hi Rami,

Can you check in strategy profile whether check box use plg-Rel Min interval f.inf.scheduling is checked, if it is checked remove that check box and then try scheduling order.

If results are not coming correctly please give details of finish date and time specified and start date of both operation.

Regards,

Santosh

Dear Santosh,

I remove check box for Use Planning-Related Minimum Interval

The result :-

Start Date Operation A : 17.03.2011 14:59:59 & End 17.03.2011 14:59:59

End Date Operation B : 18.03.2011 07:00:00 & End 18.03.2011 15:00:00

The same Result as before

Rami
