MRP Question

[Former Member]

I have an externally procured product which has a sales order for delivery date of 01/06/2009 created on 01/06/2009. Since there was no stock on 01/06/2009, system confirmed 0 qty on 01/6/2009 and confirmed the ordered qty on 02/17/2009( Pland Del time in material master for this material: 42 days). When MRP ran for this material Purchase requisition was created for 04/01/2009.

I need your help understanding why system is doing all forwards. We want the system to propose a purchase requisition backwards not forwards. Pl. help me how to fix this thing.

Thanks in advance,

KG

Hi Kelly,

In OPPQ, click on Start in Past & tick the checkbox for your plant.

In OPU5, for your plant, select scheduling type as backwards.

Hope the above resolves the issue faced by you.

Srini are you answering on behalf of kelly or just guessing that it is PD?

If you're answering on behalf of kelly, can you also check in OPPQ whether the start date in past indicator is ticked?

I am on ECC 6.0, in OPPQ in the Maintain Planning Run section at the bottom I see Start in Past button, when i press on that i find that tick box.

Which version are you working on?

[Former Member · Accepted solution]

We are in 4.7. To make sure we are talking the same.. I go in OPPQ.Click on Maintain, Enter Plant,Maintain..

I click on Param.Detailed Sched. .. then go in and enter.. Double click on my plant..In there is there is a block that says Scheduling control for detailed scheduling.. In that there is Scheduling type: 2 backwards, Automatic log - Checked and below Scheduling type is Start in past..where it takes only days..

There is other one in OPPQ .. Enter the plant and then it shows several buttons. One in the right side bottom says Order start in Past .. When I click on that, for my plant, the value for start in past allow.. is Un-checked.

Which one do we need to change? Pl. advise

Thanks,

Kelly -

Make sure to check the source list for the material in ME03. If there is a fixed source list or a preferred vendor for this material navigate to that info record. Check the lead time of the info record... it is possible that is different from your material master lead time of 42 days. The system will use the material master settings to come up with an initial requirements date, in this case the 42 days. When MRP executes the system will create a purchase req using the fixed vendor if one is defined.. the time of the purchase requisition will then be determined from the info record times.. not from the material master time.

Hope that helps a little...

Hi,

In configuration SPRO in scheduling parameters for Planned order / PR set the scheduling as "Backward scheduling " and run the MRP and check it should be ok.

Hope this will help you.
