WBS Element not appearing in Sales Order Line Item


Why Field WBS Element (COBL-PS_POSID) is not displayed at the Sales Order Line Item?

  1. Go tx. VA02
  2. Select item and go to tab: Account assignment


Reason and analysis

Once  the KZVBR is determined on sales order line item with ‘E’ so after entering the plant the field WBS element is not displayed.


Please check your customising:

1. In the sales order, check the requirements type (VBAP-BEDAE).

  • Sales order (VA02) check requirement type on tab “Procurement” :


2. In OVZH, check the requirement class assigned to the requirements type.


3. In OVZG, for the requirement class, check the “Account Assignment Category” (V_T459K-KNTTP).


4. In OME9, check the “Consumption posting indicator” (V_T163K-KZVBR).


If you want the WBS element (COBL-PS_POSID) to be displayed in the sales order item, this “Consumption posting indicator” should not be E or P.


Summary of Transactions:

OVZI:  Assign the requirement type to the item category

OVZH: Assign the requirement class to the requirement type

OVZG: Customize the requirement class (select the

OME9: Customize the Account Assignment Category (select the  consumption posting indicator VBAP-KZVBR)

      Hi zsuzsanna,

      Have you checked strategy field (with 85) assigned in Material master or not?

      Check whether you are assigning exact requirement class to requirement type?

      Because requirement type is defined based on  item category and  MRP type

      combination.Also check whether  the exact requirement class is assigned with respect

      to Assembly/internal project , requirement type and item category combination.

      Hi zsuzsanna

      I have few comments to make here.

      1. We dont generally change any account assignment settings in customisings. We only use the correct AAC in requirements class.

      2. If a WBS element has to be used as account assignment object in Sales order, there are some preconditions apart from the requirement class

           a) As you have said, the account assignment indicator should be P or Q, and the special stock indicator can be either sales order based "E" or project based "P"

           b) The set up mentioned in a alone will not help us to assign a WBS in the sales order item. The WBS element should be marked as an "Account Assignment element" which is one of the 3 functions a WBS can perform. If this is not done, then assignment of that WBS in SO is not possible.

      Having said these, the document you have created captures the essence of how requirement class works which not many are aware of. Thanks for this contribution
