Hello

Total replenishment lead time is not considered by MRP. You should use the in-house production time or the planned delivery time (external procurement).

In addition, make sure that the setting "start in the past" is not checked in transaction OPPQ.

Hello

In house production time is calculated in working days. Therefore, this difference should be caused by weekends or holidays,

Hi Vijesh,

To see the plant calendar, go to SCAL, choose Factory Calendar.

click on your Factory Calendar ID, choose Display Calendar,

Click on the Year, and then choose Display Year.

To know which Factory Calendar ID you use in the plant, go to

SPRO > Enterprise Structure > Definition > Logistic - General > Define, Copy, Delete, Check Plant, and choose define plant.

Best Regards,

Hi


Can you please share a screenshot from transaction MD05? It is usually better to understand the MRP results and rescheduling messages.

As you are running monthly lot size, system creates PlOrd every 1st of the month.

If there is some previous requirement not covered, it issues a message of rescheduling in the past-

Hello

The screenshot from MD05 clearly points that one of the planned order would be created on 01.08 and another on 01.09. They were probably not created on those dates because you do not allow start in the past, so they are created considering today as the start date.

Hi Vijesh,

I realized that you are running MRP (MD02/MD03) with scheduling = 1 (determination of basic dates for planned). That is, you aren't considering the routing for the planned, only the date in the materials master.

You said that you updated the lead time by 30 in MRP 3, but the result in MRP considers:

  • The Total replenishment lead time field is maintained: In this case, the time maintained in this field is used for the availability check.
  • The Total replenishment lead time field is not maintained: In this case, the system reads the in-house production time and, if available, the goods receipt processing time, and interprets the total of these two times as the replenishment lead time for the availability check.

Because you updated the value for 30, when you executed the MRP, the system calculated the end date and start's date again and said you should have converted the orders there is some days ago for to answer the necessity. 

Now, you need to adjust your stock/requirements list, and after to control your process for to convert the orders always in opening date.

Best Regards.

Hi Vijesh,

Do you produces this material in-house or purchase?

The field "in-house production" you can to use for material that you same execute the production, but this field has some caracteristics (how Caetano said), this field works it in working days.

This material has a routing?

Hi Vijesh,

Can you share a screenshot of the detailed scheduling of same planned order?

I need to see the start and end dates and times. And the capacity requirement.

Other thing, what Dario said is relevant.

What is the Lot Size (MRP 1) that you are using?

Hi Vijesh,

This field only really serves to over-ride the fields Caetano has mentioned above in the generation of the Replenishment Lead Time Indicator on the md04 screen as displayed below,

which is toggled on / off with the button highlighted.

Darrell.
