Procuring materials with different delivery timelines

Hi all,

I referred to many threads did not get exact answer and i am new to MM.

My customer orders few materials which are having high lead delivery times well before BOM is built based on forecasting and confirmed orders received. Now they are moving process according to which they need to order any material only after BOM is received from engineering tool. So now problem is by the time they get bom which has this materials which take long time to get in to stock the production time line will increase. Because they order after BOM is received and few of materials in bom take long time and few take shorter time. Does SAP has any best process to handle the same.

What i understand is we can put planned delivery time or lead time in MM which can raise PRs based on this time line put here but i am not able to synchronize between long lead items and short lead ones.

What customer wants: By the time BOM reaches SAP from design tool some how long lead materials should be ordered and short lead can be ordered after BOM in SAP.

So can some suggest me best model which can be followed for this

    There are some uncertainties in your story.

    How can purchasing know what raw material to order if the BOM for a finished good does not even exist?

    Probably because the knowledge is already wide spread and present and just the data is not maintained.

    Then you say "Now they are moving process according to which they need to order any material only after BOM is received from engineering tool." This is actually your business decision. People who took that decision should be aware of the consequences. If not then you should have told them. SAP cannot solve this situation for you. If a material has 60 days lead time and you get the BOM only 30 days before it is needed, then you can't just make it at the desired time, then you have to shift your production and put your customer off, except you have some wizards as buyers who are able to find a new supplier in the last minute who is able to deliver it in 30 days.

    Of course you enter the planned delivery time in material master, otherwise SAP could not know about the delivery times in its MRP planning. But you can only enter the days as a best guess until you really know it better from discussions with several vendors. And then again you have to decide if you use an average time or a best case or a worst case scenario for your planning.

    "What customer wants: By the time BOM reaches SAP from design tool some how long lead materials should be ordered and short lead can be ordered after BOM in SAP." How can anyone know about long or short lead times of an unknown raw material? You only know the component after you have the BOM. And if the BOM reaches SAP and you see that there is a component which has long lead times then you can't get into a time machine to order it last month. So you can just start ordering on that day, which is as well the wanted process, you wrote yourself that you are only supposed to order after the BOM is in SAP.

    • Hi Jurgen thanks for the reply but i still dont understand why are u angry on me. You could have just told its not possible.

      Hope u did not understand my statement clearly on PRs. Yes PRs are raised by MRP but its raised for all other materials other than long lead because for long lead already PRs are raised, this i have mentioned clearly. So no issues with existing process. Issue comes with new business decision.

      Regarding To be: Every knows data is needed in SAP. I have clearly mentioned in my problem statement because of global business regional production has got a new problem of this long lead items and they trying a way to satisfy both global rules and still maintain delivery timelines to customer. I am trying to help them to my best.

      Hi all, I understand from Jurgen that its not possible to handle in SAP.

      My concern is if some one has encountered such issue how did they handle and is there any possibility in SAP to handle such situation. I have already put my view points also. Any other ideas from any others please. Inputs and opinions from others also is requested here please
