MRP result when component not available

[Former Member]

Hi gurus,

We are trying to run MRP. We have a finished product on the higher level which needs to be produced on October, 14th (the production order has to start on October, 10th beacuse of the processing time in the material master data). But we have a component of this finished product which can be available only on November, 5th.

When we run MRP, we have the exception 30 'Plan process according to schedule' for the component and a replenishment on november, 5th instead of October, 10th.

But on the finished product level, we don't have any messages.

We understand that it is the standard behaviour of SAP and that we can't do bottom up planning with PP but what can we do in this situation?

Is there an other way to be informed of the unavailability of the component (not the exception message)?

MRP will run by jobs so we don't check each material on each MRP run.

Thank you in advance,

Hi,

The MRP in ECC does not consider what is the planning situation of your components when your finished goods are planned. The MRP starts planning the finished good and once the planning proposal is done, it moves to the following level of the BOM.

In other words, the MRP always starts planning according to the Low-Level code, this is a top down planning. Once the first level is planned, the system goes to the second level. If a the MRP finds a planning constraint in the second level, it will not modify the planning proposal already done for the first level.

You can work with the exception messages or create an enhancement in ECC according to your needs: maybe, after the first MRP execution on your BOMs levels, you can collect the exception messages and rerun the MRP at the top level (like a bottom up rescheduling).

Kind Regards,

Mariano

Hi,

1)  U have maintained component planned delivery time in no of days in material master. when u run MRP, in MRP result go to md04( stock requirement list) there select any MRP element as (planned order if more than 1 planned order generate) & press "show overview tree", there u can see every BOM component availability date after considering available stock & requirement.

2) For header level after MRP run, planned order generate, when planned order convert into production / process order in dates tab in order committed date show, means on that day all BOM component stock available.

hope u find ur solution, revert if any other query.

one more point i want add...that

In production order (T code CO02 / CO40 ) go to material availability check, system will show missing part list & there coming date if stock not available as per order requirement.

you can configure availability check for planned orders according to your scenario and run a collective Collective Availability Check and evaluate the results.

Hello

Another alternative is to use the order report (transaction MD4C).

Here you will be informed of all the exception messages for the low-level components and you will be able to take actions to avoid the shortage.
