Changing of Material Valuation Classes

Former Member
0 Kudos

Currently changing of material valuation classes in standard SAP can be achieved if :

1. If valuated stocks already exist, you can change the valuation class

only as follows:

a) Post the stocks of the material to an interim account.

b) Change the valuation class in the material master record.

c) Post the stocks of the material back to their original account

2. If open purchase orders already exist, you can only change the

valuation class if you first flag the corresponding purchase order

items for deletion.

3. If production orders exist for which a goods movement has already

taken place, you can only change the valuation class if you first

set the status of the production orders to Deleted.

Is there any other ways that point 2 and 3 can be avoided when trying to change material valuation classes?

Thanks,

CW

Hi CW,

This really shouldn't cause you a major problem.

You can use the mass change transaction to flag and then inflag the PO items as deleted (not sure if the same option is available in PP?)

But it is something that HAS to be done to ensure that receipts and reversals do not use different accounts and therefore cause financial problems.

It is important to realise that changing the valuation class on a material that is currently being used is a VERY risky thing to do and so the controls that SAP insist on are very essential.

I wish we could give you the answer you wanted but it is sometimes as important to clarify what you CANNOT do as it is to tell you what you CAN do.

Hi Steve,

Appreciate your answer...However we do not have the luxury to freeze/stop PP orders and Production Orders. Here, we are talking about few thousands orders in the live system and no down time can be afforded!

HI,

That makes it very tricky doesn't it.

But if this is done at your quietes time (if there is one, but even 24hour 7 day operations have a quiet time?)

You can still carry on producing but yopu will have to hold off from posting anything while the PP orders are blocked/deleted.

I guess that you could use an LSMW job to make sure that the time taken is a minimum.

The job just needs to be fed a list of all PP orders containing the material/s involved and it can then set the delete flags and reset them in seconds (with a manual change of the Valuation class inbetween).

There is not going to be a clean and easy solution to this, all we can do is to try to reduce the pain.

Hi Steve,

I am afraid to say that we have a robust interface from other legacies on a 24X7 basis for PU and PP orders creation. To stop for a 5 mins will mean losses in terms of millions! We can't afford that!

Hi,

Then we will have to look other options.

Why do you need to change the valuation class? Is it wrong or do you just want to use different accounts?

I am sorry to disappoint you but the answer is no. As you have seen in the message appearing in the "performance assistant", SAP doesn't support such flexibility just to ensure that SAP remains very strong in its INTEGRATED APPROACH.
