Operation overlapping

[Former Member]

The operation with std values set up and machine time are getting overlapped on the previous operation.

But the operation with std value key teardown time only is not getting overlapped to the previous operation.

settings on operation overview, for all the operations is,

required overlapping - checked

Min. Send-Ahead Qty - 100 ea

Hi,

Logically the system behavior seems to be right to me.

Overlapping is for component level activities e.g machining.

When few components of the lot have undergone the activity, you send them ahead to

effectively reduce the lead time for production. But setup and tear down are lot level activities.

That is they are done, once per lot (typically). When it is not a component level activity, how can you have

overlapping and send ahead items. it doesnt make sense to say that 100 nos are being sent ahead since teardown has been completed on only 100 nos right?? because teardown is a wrok center activity and not a component activity.

Besides teardown should be the end of an operaition or beginning of the next operation, why do you want to have an operation as only teardown. I am only thinking aloud, please correct me if i am wrong.

Solution,

Define

- new parameter ZSAP01

with time dimention & Origin - 2 Standard value in the operation

- New std value key ZPP1 with Second parameter ZSAP01

- New formula key ZPP_01 with formula ZSAP01 * SAP_09 / SAP_08 / SAP_11

Use this Std value key and the defined formula in the Work center.

Dear,

In CA02 - operation overview - select oprn with std values set up and machine time - go to oprn details screen - overlapping tab . pls do the foll settings

Overlapping Indicator : Required Overlapping

Min send ahead qty : 100 Ea

It will work for you.
