Change of unit of measure in master( UOM)

[Former Member]

Hi,

If we change UOM of a material 0r service in existing master, does it impact anywhere in pld data.

e.g. POs created, service entries passed.(Open & closed)

Hi,

An effect will definately be there. Some considerable effect can be there outside the system as to agreements with vendor, internal standards etc.,

But pl. just maintain unit conversions in material master record itself so that it will not be required to alter data at many places.

Please refer to SAP note 138767 for more information about changing the base UOM as below :

Within the material master record maintenance, you want to change the

base unit of measure (base unit). During the change, the system performs

extensive checks in order to avoid inconsistencies in the applications

which use the material master.

In particular, the following checks are performed:

- The base unit must not be defined as an alternative unit of

measure for the material

- No International Article Number must be assigned to the base

unit

- No proportion/product units must be defined for the material

- No configurable material must be assigned

- The material must not be used as a configurable material

- Stock must neither exist for the previous period nor for the

current period

- No physical inventory must be active

- No reservations or dependent requirements must exist for which

the deletion indicator is not set

- No planned orders must exist

- No purchase requisitions, purchase orders or scheduling

agreements must exist for which the deletion indicator is not

set

- No WM transfer requirements, no WM quants or no WM posting

change notices must exist

- The material must not be a bill of material

- The material must not be used as a production resource/tool

- The material must not be used in task lists

- No standard cost estimate must exist for the current or future

period

- No production orders must exist

- No planned independent requirements must exist

- No run schedule headers must exist

- If the base unit has dimensions, no serial number profile must

be assigned

- No sales and distribution documents must exist which have

status Not processed or Partially processed.

Hi,

System will only allow you to modify the UOM in Material Master Basic View 1, if it is a new material created or No topen transaction are available (like open P.O, Plnd Order , Stock, P.R's etc)

Dear,

If there is any pending PR's or PO's exist..

It won't be allowed to change the UOM for said matcode.

Pl delete the said pr's first and also delete the stock..

That for You have to delete all the task list by using QSR6..if only QM module updated..

Pl check and confirm..

Hi,

First of all the system will not allow to change UOM if any transaction data exisists.

It will show the The base unit of measure cannot be changed; choose "Display errors".

In display errors it will show the stocks,PRs,POs and Sales data.

And it will effect the total planning.

Hi,

Any change in the Base UOM post transactions certainly have far reaching effects...

In case you have any open POs etc.. the system will not allow you to change the Base Unit.

Thanks & Regards
