Backward / Forward Scheduling doubts

[Former Member]

Hello,

We have some doubts around the concept of backward/forward scheduling.

We have a given material with a forecast input in the MD61, lets say 500 pcs per month (march, april and may).

We raise a sales order for it with the qty of 1000 pcs for April, 30th.

If we confirm for "Delivery proposal" on the availability check, in MD73 the system occupies correctly the planning slots of march and april.

But if we choose the "complete delivery" button, the necessity is assigned to the may slot and leaves 500 pcs to be confirmed.

In other words, during availability check, if we choose delivery proposal, the system carries out backward scheduling. Otherwise, it carries out the forward scheduling.

Our intent is to have backwards scheduling always.

Any ideas of how to solve it?

Sorry, I think I mispelled our intention, my bad. We need to have backwards scheduling first, if the system cannot confirm all quantities, then the forward scheduling should be carried out.

If stock is not confirmed once backward scheduling happens, then system will automatically perform forward scheduling.

Perfect! We will do some testing and will feedback the results.

Thanks for now.

Execute OVLY, select your order type and execute. There tick the box "Backwards".

Dear Adriano

You can achieve this by ticking the option 'Backwards' while defining scheduling for sales document types.

The path is as follows:

SPRO>LO Execution>Shipping>Basic Shipping Functions>Scheduling>Del Scheduling & Trans Scheduling>Define Scheduling By Sales Doc Type.

In that screen, against your sales doc type, tick the check box 'Backwards'.

This is what it does:

Carry out backwards delivery scheduling only

Indicates that the system is to carry out only backwards scheduling for all schedule lines in the sales document.

Use

When you change a sales document, such as adding schedule lines or rescheduling, the system carries out delivery scheduling for all lines. In some cases, the system performs forward scheduling which may have the undesirable affect of rescheduling lines that have already been confirmed.

Procedure

Mark this indicator to deactivate forward scheduling.

Note that when this indicator is set, the system may determine a material availability date that lies in the past.

Thanks
