Maintain Storage Location

Updated May 18, 2018

MMSC - Collective entry of Storage Location for a material.

Insert new or delete un-used Storage Location.

Maintain whether the storage location was included or excluded from MRP run.

Block Storage Location from further posting

1. You can block the storage location of a material without affecting the rest of the location using the same material.
Create a Physical Inventory document for the storage location with transaction MI01

Select the Posting Block checkbox.
This would prevent transactions from occurring until you either post or delete the physical inventory document.
(There is no impact, unless you do a post difference for the physical inventory document.)

2. Another method is to rename the storage location name.

  • Go to transaction OX09

  • Edit -> Copy as (copy the original storage location to a new name, replacing the first character e.g. ZXXX)

  • Edit -> Delete (delete the original storage location)


  • Do the reverse if you want back the original storage location.

    Valuation Class for Material Group

    In 4.6x and 4.5b, you can assign valuation class to Material Group.

    It is useful in the sense that user do not have to manually do an Account Assignments.

    For stock items, valuation class cannot be changed whenever the stock on hand is not zero.

    Valuation class are tied to a G/L account.

    A change of valuation class means a change of G/L account.

    In FI concept, you have to debit and credit to balance the G/L account. That is why your stock must be zero before the system allows you to changed the valuation class. If it is not zero, you have to either transfer it to another material or do a dummy issues. After changing the valuation class, do reversal entries for the stocks which you have transfer out or you have done dummy issues.
