[Former Member]

Hi

I have entered demand in MD61 for sept , oct , nov and Dec . Lead time of mat is 66 days

Planned del time 63 + GR proc time 3.

Now I have 3 pur req in system thrown based on total req . Quantity is fine but for all pur. Req release date is 2008/09/23 . There is exception message 30 and some rescheduling dates shown. What is a meaning of that?

I need pur. Req for dec should be thrown / release in oct .

Hi,

In your case, three PR's generated on same date, this is due to lot size maintained in Material master.

Is any scheduling agreement is maintained in ur case?

There is another option available. You can convert all the PR's on same said date,

but can put the delivery date in Purchase order as per ur requirement.

Hope this clarification will be helpful to you.

Hi Neal,

Rescheduling normally happen when there are firmed MRP Element, such as PO or production order, which is late, hence MRP will propose you to expedite this order in order to fulfill the requirement on these date.

Hi,

Yes right, You defined the rescheduling parameters in Customizing for MRP.

An important parameters is the rescheduling horizon period to be included.

1. OPPQ per plant to Carry out overall maintenance of plant parameters.

2. OPPR per MRP group to Carry out overall maintenance of MRP groups.

You can also define tolerance values for the creation of exception messages.

These values define a time period in which no exception message is to be created, despite the fact that a rescheduling proposal may exist.

Bring process forward (reschedule in)

Within this rescheduling horizon, the net requirements calculation checks whether, after a requirement, a firmed receipt exists, which can be used to cover this requirement. Then the system displays a rescheduling date as well as the exception message Bring process forward for this receipt. The net requirements calculation then uses this receipt and the

system will only create another procurement proposal if the receipt quantity is not sufficient to cover the complete requirement. Several firmed receipts can be used to cover one requirement.

The rescheduling horizon is always calculated from the MRP date.

Check this also,

Hope clear to you.
