ML81N Account Determination WRX issue


I want to assign multiple GL during SES but unable to do this. If I am deviating from the GL provided in OBYC at WRX it gives error "147 Account requires asignment to CO object". I will be very much thankful for any kind of help.

    Service entry sheet is created with refer to the service PO. so first create the service po with muliple account assignment so that there is a possibility of multiple account assignment in SES.

    The g/l account in service po is automatically picked up by settings in OBYC for GBB VBR, another possibility by the material group assigned to valuation class in customizing.

    • Hi Asad,

      In standard SAP, it is not possible to have multiple G/L to WRX for SES.

      Go through the below SAP Note, which explains this process in detail,

      Note 64204 - MM-SRV: Determination of the GR/IR clearing account

      As per this note,

      The valuation class from the service master is not used for the GR/IR clearing account determination (Transaction WRX) when posting the external services management. Instead, valuation class ' ' is assumed.Thus, the same account is found as if you make a posting for a purchase order with material number 0.This account determination procedure was chosen because there are generally several services with different valuation classes for each purchase order item.Thus, the GR/IR clearing account cannot be determined unambiguously by means of the valuation classes from the service master.

      Solution :

      1. In order to determine the GR/IR clearing account for the service entry sheet, add an entry with valuation class ' ' in the account determination table for transaction/event WRX. (Customizing path: 'Materials Management -> Valuation and Account Assignment -> Account Determination -> Create automatic postings)

      2. As of Release 4.0, a user exit is available which you can use to set the account grouping code for transaction/event WRX in relation to the characteristics of the purchase order. Thus the determination of the GR/IR account can be controlled separately for material and service orders via the user exit. You can activate the user exit via customer enhancement LMR1M002.

    No valuation class assignment needed for Service procurement in t.code:OBYC for WRX key.

    Use t.code: OBYC, Enter Chart of Account, Double click WRX & enter your G/L account, keep valuation class BLANK & save.


    Generally for material in t.code OBYC,WRX assigned to G/L account of GR/IR-Clring(material) with valuation grouping code ,valuation class with Chart of Account.
