EHS : Waste Management ( Why PO is created)

Hi All,

Greetings!!!

I am working on EHS scenarios. I need your help in Waste Management module.

While working on the same, I need to know why PO is created in this process?

After creating entry document( where we enter the amount of waste needed to be disposed), why we need procurement?

Is it for the procurement of items needed for disposal?

As i have very limited knowledge in EHS, please help in this regard.

Thanks and regards

Tarun Gupta

    Dear Tarun,

    The items (Waste Materials) that has to be disposed through a vendor is mentioned in the PO(Purchase Order).

    I think you should get to know the process flow in EHS-WA to get to know on why a 'purchase order' is required.

    From Industrial perspective, the when a waste is generated during a process, it is collected and kept in storage bins based on the nature (hazardous/non-hazardous) of the waste. A threshold limit will be there for the storage bins/locations. This stored waste is either given to some vendors for the safe disposal or is sold to any parties/customer or send for recycling. If it is given to vendors for the safe disposal, you are giving the vendor money and asking to do the disposal and hence you have to create a Purchase order. And, if you are selling it to a customer or if revenue is generated from the waste, you create a Sales order for the disposal.

    In SAP, the disposal processing starts with the creation of an entry document (WA-MM) when the waste is generated. The generated waste is then transferred of waste to storage locations/bins via inventory posting (MM). The posted quantity in the bins are cleared by creating purchase order/sales order through proper channel depending on the business (MM/SD). You create a Disposal Document then (WA). Invoice & Release of payment is carried out (FI). The Waste Manifest is printed (WA).

    Process Flow Summary:-

    Entry Document --> Inventory Posting--> Purchase Order for ext disposal--> Create Disposal Document-->Invoice and Release of Payment--> Print Waste Manifest.

    Key:

    WA - Waste Management

    MM - Material Management

    SD - Sales & Distribution

    FI - Finance

    For detailed reference, go through Purchase Order - Waste Management (EHS-WA) - SAP Library

    Cheers!

    -Chris.

      Thank you for replying, I was already started to prepare a function for the sales process. I was wondering if there were already a module function ready for it as there is for a purchase order.

      The documentation is a little bit confuse.

      Regards,

    Hello,

    It's simple to explain why a PO is needed. You need transport, you need a waste disposer, This is done using standard SAP functions like a PO. When you want to create a PO in background you are able to use the standard function modules for creating an PO. In the Function module you define the type of PO that has to be created.
