But When I gone to VKM1, I cannot find the document. When I go to VKM3 I found it.
As I known, VKM1 should can display all the document which has credit check status 'B'.
Do you know any reason about not listed in VKM1?
Answer:
VKM1 is for cases where credit management is controlled for all of a customer's transactions while VKM3 is used when control is on a sales order document basis.
Also VKM1 transaction is to get the sales orders which are blocked due to credit check. To find SO is blocked for Credit Check Program reads VBUK table with Overall Credit Status (CMGST field) where it is not equal to D (D means Credit Block Released). As soon as you release the document from Credit Check it will not show up in VKM1 transaction.
Whereas VKM3 is to select the Sales Orders based on Order Number. It does not matter whether the Sales Order is blocked for Credit Check or not. When you specify the Sales Order number in selection screen it will bring the Sales Orders based on your selection and does not check VBUK status, but it reads the VBUK-CMGST field. If you scroll right in the list, there's a field OVCS (I believe that is the right one is shown either A, B, C or D).
Therefore, the main difference between VKM1 and VKM3 mainly stands in the check of document in overall credit status B.
- T-code VKM1
corresponds to RVKRED02
- T-code VKM3
corresponds to EVKRED04
Via VKM3 you will always get a record as result. This because the only key parameters this report is checking is the document number and it is ignoring all the other key fields.
Via VKM1 you may not get always a record as (per standard) it should check if CMGST EQ 'B'.
As general advice, check both programs and be sure that there is no specific change out of the standard.
If your document has already CMGST equal to B I would proceed as follow:
1. check the customer is open in
the relative Credit Area (as VKM3
is not checking this point)
2. check the settings of the risk
category assigned to the customer
3. check if the order was already
previously released and then got blocked again due to modifications (some
change in the sales document may not properly or partially update the status
in the order)
4. if yes point 3, check if it
was blocked during last 24 hours
5. try to replicate the same scenario
using the same customer/product/quantity
6. try to replicate the same scenario
changing one condition at time and analyzing the behavior of VBUK
7. check the account group for
the customer and see if it the payer as well (when SP is NE to PY and you
run VKM1
using SP then the result is not what you expect)
8. check if PY of SP is open in
credit area
Here above only few point to check that should help you in verifying your issue.
