Reply from sapnomad on Mar 21 at 5:01 PM Just for the record, I've been able to change the base UOM on several occasions. There is no reason why you have to create a new material number, and for various reasons that can be a lousy solution. Here is my company-specific process. If you are not running MRP or WM, then you can skip those steps. Sorry, the bullet/numbering formatting got stripped....

Problem
An SAP material master needs to have its base unit of measure (UOM) changed.
Solution
Changing the base UOM is not an easy undertaking due to the integration of the material throughout the SAP MM system. When trying to change the UOM, the system goes through a series of validations. If there is a key dependency that has not been addressed, the system will not allow you to make the UOM change. Thus, the solution involves a number of preliminary steps to remove the dependencies that would otherwise not allow the UOM to be changed by the system.
For the material in question, follow these steps. Note that some steps may depend on a prior step, so following this sequence is suggested.
Address current or planned stock movements
Close any open purchase orders (Identify: ME2N; Close: Either complete goods receipt or delete open quantity via ME22N)
Close any open scheduling agreements (Identify: ME3N; Close: ME32)
When deleting PO line, system will re-open the purchase requisition. You can note the PR number and delete it immediately, or wait until next step.
Close any open purchase requisitions (Identify: ME5A; Delete: ME52N)
Complete in-transit stock, i.e. plant to plant transfer (Identify: MMBE)
Confirm any open transfer orders (Identify and Confirm: LT24)
Eliminate any open transfer requirements (Identify: LB11; Delete, if appropriate: LB02)
Eliminate any independent requirements (visible in MD62 or MD04). (For SAP support team: these are stored in table PBIM)
Address inventory
Close any open MM physical inventory documents (Identify: MI22; Delete, if appropriate: MI02)
Close any open WM physical inventory documents (Identify: LX22; Delete, if appropriate: LI02N)
Clear stock with posting date in previous period and current period
As a rule you cannot have any stock in the previous or current period. You can view the previous and current period stock in the material master plant and storage location views. While the stock is almost always in storage location 2000, should that not be the case, you need to clear the stock at whichever storage location it is assigned to.
If there is previous period stock, begin by transacting MB1C with mtype 562 for that stock quantity. Use the last day of the prior period. For example, if we are currently in February period, use posting date January 31 (the document date can remain today's date)
Now confirm current period stock (MB52 or material master) and repeat the same MB1C mtype 562 transaction for that quantity if necessary (if quantity in previous period is same as current period, current period would be cleared once previous period got cleared). Take note of the storage bins that contain the stock.
Perform base UOM change
Execute MM02, perform the UOM change, and Save
System will peform its validations. If there are errors, likely due to a failure in performing above steps, choose Display Errors and proceed to fix
System may also generate warnings. A common warning is if RFQ, info records or contracts exist for the material. At this point, the system will display a dialog box asking you to enter the conversion from the old to the new base UOM. Thus, the info record can be automatically updated with the new base UOM.
Update the material's new standard price
Enter INFRA ticket to SAP Finance with Material Price Change request
Approval must be given by the Plant Finance Director
Security is notified to unlock transaction MR21
Finance to update price (MR21), and security locks the transaction
Update info record price, as necessary
Restore correct inventory
Perform the above MB1C steps in reverse. First use mtype 501 with a prior period posting date (e.g. January 31) to add inventory. It is important to use 501 and not 561 because the latter is not integrated with WM and will not generate any transfer orders
Next repeat for current period, using the same stock quantity from above 562 transaction. Again, this step may not be necessary.
Make sure above two steps are using the stock quantity converted for the new base unit of measure!
Remember to create the transfer orders in foreground (to specify current bin locations), confirm the new transfer orders, and attach the new SU labels.
Address any MRP planning concerns
If running consumption based planning, the historical consumption data (table MVER) needs to be manually updated to reflect consumption data in the new unit of measure. Contact a member of the SAP supply chain team for assistance.
If using static safety stock or reorder point planning, adjust the material master values for the new unit of measure

Subject: Changing Base Unit of Measure
Hi,
I have encounter one problem when changing base unit of measurement from EA to KG.I deleted all the Pos , PRs , Reservation and removed stocks also.
But still I am facing an error as per below:
The base unit of measure cannot be changed.
The reasons for this are:
Stocks already exist at the vendor's.
Material Plnt Batch S Vendor
100003361 1101 O CLS00307
100003361 1101 O CLT00056
I also transfer stock from Vendor's end to plant but it shows error as per above.
Please do helpful.
Thanks & Regards,
Krishna D Joshi |
