Deactivate Material-Ledger

[Former Member]

Hello,

we have activated Material-Ledger only in our test system client 400.

Now we want to deactivate it because if Material-Ledger is active we have problems with "Split Valuation".

We have found out that Material-Ledger can be deactivated with report SAPRCKMJX. (OSS 108374, 425487).

But a consultant means that activating Material-Ledger does change also system wide settings. Is this correct?

Does this report really undo all settings of Material-Ledger? Also system wide settings if they are set?

At the moment a client copy is not possible for us because we have done some test customizing setting in client 400.

But would be a client copy from production system reset all settings?

How can we test that all settings of Material-Ledger are reset?

Are there any dependences if we deactivate Material-Ledger?

Thanks for your support

Hi Arnfried,

The consequences of deactivating the Material Ledger are:

- All historical data is deleted

- No valuation of materials in parallel currencies

- Purchase order History is deleted and cannot be recreated

- Actual Costing is not possible any more

- Actual Cost Component Split information is deleted

In fact you will delete all the Material Ledger tables.

How to deactivate material ledger is explained in note 108374.

The note advises you to contact the Development Support just to make

you aware of the consequences.

The runtime of program SAPRCKMJX depends on the amount of ML data in

your system and it is hard to estimate.

Note 425487 explains the limitations for deactivating ML in productive

1. systems.

When you start using Material Ledger, you have two steps:

   - 'activate' ML in SPRO, and then

   - 'set ML as productive' by running CKMSTART.

When we say 'deactivate ML' in note 425487, we mean both steps:

   - reset ML from productive by running report SAPRCKMJX

   - 'deactivate' ML in SPRO.

Please test the deactivation on your test system first. If you are

satisfied with the results you can proceed with your productive system.

Hope this helps you.

Regards,

Cristiano.

Hello Cristiano,

thanks for your answer.

As we have ML only activated in our test system it seams that there is no problem deactivating it!

We have only reservations that activation ML has changed system wide settings.

Do you know if ML changes system wide settings?

If so our customizing client 200 (in the same system) would  have also changed !?

Thanks

Hi,

As explained in the note 108374, the program SAPRCKMJX does NOT

reset the Customizing of the material ledger.

Thus, in Customizing of the material ledger you must remove the active

indicator manually.

Hi,

While executing the de-activation program I am getting error message "Error during migration of order history to plant XXXX"

How can proceed for the same. It is in test system.
