How to debug credit check issues

Posted by Smile Zhang in SAP ERP SD Sales on Apr 4, 2012 8:25:36 AM

Funtion modules for credit check:
SD_ORDER_CREDIT_CHECK-->for sales order
SD_DELIVERY_CREDIT_CHECK--->for delivery
SM_ORDER_CREDIT_CHECK-->for service order/CRM

1.Take sales order for example, set breakpoint at SD_ORDER_CREDIT_CHECK->
Enter a new item or change item quantity(cost) to trigger a new check

When FM is hitted, search for the coding for specific check, for example static check
->

* static check                                                       
   if no_check is initial.                                          
     clear rkvbuk-cmpsa.                                              
     if t691f-cmpaa eq true                                           
     and                                                              
     ( update      eq true or                                         
       t691f-cecki eq true or                                         
       t691f-strea eq con_error ).                                    
       perform static_credit_check using  update         <<<<<<<<Set here     

                                                xvbak-kkber                 
                                          xvbak-knkli                 
                                          flg_order                   
                                          flg_delivery                
                                    changing                          
                                      rc_check_a rc_check rc_warning  
                                      rc_error rc_status_set          
                                      rkvbuk-cmpsa.

xvbak-kkber                    1000          -->credit control area
xvbak-knkli                    0000001050    -->credit account
flg_order                      X

2.When above BP is hit, F5 to enter the Form for static check

PERFORM CREDIT_EXPOSURE_GET is to get the exposure
T691F-STVAW and T691F-STVLW are the "open order" and "open delivery" field in OVA8

SCC_OPEN_ORDER    -->open order value
SCC_OPEN_DELIVERY -->open delivery value
SCC_OPEN_INVOICE  -->open invoice value

3.PERFORM CREDIT_DELTA_ORDER is to calculate the current sales order value
Set BP at the next line after this Form and Press F5 to enter this FORM->

CALL FUNCTION 'MCV_STATISTICS_ORDER' -->FM for statistics update for order

SET BP at subroutine->
Program                       SAPLMCS1
Subroutine/Method/Module      OFFENE_WERTE_EINT

Then search for PERFORM cmpre_calculate(saplvkmp)-->program for credit price calculation

4.After CREDIT_DELTA_ORDER is complete DELTA_OEIKW is filled with current sales order

value, it is added to SCC_OPEN_ORDER(open order value)

SCC_SUM_OPENS = SCC_SUM_OPENS + SCC_OPEN_DELIVERY
                               + SCC_OPEN_INVOICE.

Open order, delivery and invoice value is summed up.

IF SCC_SUM_OPENS GT SAV_KNKK_KLIMK.
  PERFORM MESSAGE_EXCEEDED_VALUE USING SCC_FLG_ORDER SCC_SUM_OPENS.
  MOVE CON_RC_NOK TO SCC_RC.
ENDIF.

Then it is compared with the credit limit maintained in FD32.

If the open value is large than credit limit, message is issued to inform user that the credit check failed.
The message type depends on setting in OVA8.
