Change of UOM in material master?

Dear SAPIENTS,
I created a material with UOM (M)just now and than assigned to inspection plan. Now I am changing the UOM of material to Nos.. I was getting following
Error: The base unit of measure cannot be changed
The reasons for this are
Routings already exist that are assigned to the material.
RType RtgGrp GpC Plant
Q QRW6MTQT 1 1100
SO I removed the material from inspection plan. But still I am getting the same error. Can anybody tell me the reason behind it?
Regards,
Kaushal Rai

Hi Kaushal,
You need to delete it from the table also.
The table is MAPL
To delete entry from table
   1. Run trx SE16n (preferable) or SE16.
   2. Enter the Table MAPL.
   3. Enter the group and counter number.
   4. Now in the command window (Where you type the T Codes) type "_&sap_edit_". And press enter.
   5. A message such "SAP editing function is activated" will flash.
   6. Execute
   7. Delete the entry.
Then change the UOM

Shyamal

UOM in Material Master

Hi,
Is it true that i cant change the UOM of material (base unit) even if there exist PO and PR for that material ( even though these are not open)? There are no scheduling aggrement too. The stock of material is 0 for this period as well as previous period. I tried to change the UOM for this material but the system gave error that the UOM cannot be change.
Dinakar

You can only change the base units of measure under the following circumstances
1.No stocks are available for the material.
2. There are no existing purchase requisitions, purchase orders, or scheduling agreements for the material.
3 At present, no purchase orders or purchase order items are being created or changed.
Run MM02 (Change Material Master immediately). - Overwrite the old base unit of measure with the new one in basic data screen. - Save the change. - System checks If a change criterion (MM02) is meeting all necessary prerequisites (as mentioned in above .System allows changing base unit of measure.
Otherwise it displays warning or error. You can display the reason for this, by choosing Display Errors (ctrl+F1) .in that take those purchase requistions and purchase orders and close it.then try again.
Generally it will be difficult to change Base UOM,intead of that you can mark that material for deletion and goahead in creatin a new material with new UOM as base UOM.
Hope it helps

Advantage of Alternative UOM as supposed to changing the UOM of material

Hi Friends,
What are the advantages of using alternative unit of measure as supposed to changing the UOM of material? &
what are the necessary activities in SAP if we change the unit of measure of the material?
Any pointers.
Regards
Ashu
Edited by: ashutosh p on Jan 14, 2010 6:29 AM

When you want to handle the material quantity in other units other than it's Base Unit, then alternate unit should be maintained.
Alternate unit is decided on the basis of area of it's usage.
If A material is having base unit PC and you want to sale it in KG then mainain the Sale Unit as KG by providing the conversion between PC and KG.
In the same way Order unit is the unit when you want to procure the material in the unit other than Base unit.
For maintaining alternate unit, it's corresponding conversion with Base unit is necessary to maintain.
You can change the base unit of material unless and untill no transactions are done on that material.

Change profit centre in material master

Dear all,
How to change profit centre in material master with stock(opening balance - 561 stock ?
What are implications of changing profit centre in material master ?
Jeyakanthan

In standard SAP it is possible to change the profit center at any time.
However this will create inconsistencies in your profit center accounting. Hence you should issue all stock first to a cost center with 201 movement, then change the profit center, then get the material back with 202 movement.
You need to make MM335 message an error message in OMT4 to allow a change only if there is no stock
If you dont follow this way, then you create inconsistencies in profit center accounting.
Because...you received your stock without profit center (actually it is a certain default profit center), if you then change the PC in your material, then each issue will be posted to the new PC, while it never had a receipt.

Please help urgently
Thanks in Advance
Neha

Hi Satyajit,
Please look at OSS Note 1069560 - Data inconsistencies: Activating integration. models in parallel, if this helps you.
Since Gross data of material is in the basic view, it is common across plants , whereas, IMs are normally designed to have material masters at plant level.
We may have same material in different IMs with different plants. Therefore changes of the basic view fields are then contained in multiple IMs. SAP advises to have a larger IM or sequential activation of IMs.
I hope this will help you .

Change UOM in Material Master Problem

Hi all expert,
Im trying to change a raw material UOM from KG to Liter in material master, i have deleted all the document related to the raw material, but when i change the UOM, it display message as below:
Material Master Maintenance
The base unit of measure cannot be changed.
The reasons for this are:
Independent requirements are already assigned to the material.
Plant MRP area
   JK01
I can't find the independent requirements so can't delete it.
Hope someone can give me advise.
Very thanks for help.

You can also see the planned ind. req. for your material from Txn. MD63
If you delete the ind. reqs. no longer appear when you access via trans.
MD62/MD63. However, the records are still in table PBIM with a
deletion flag set on field LOEVR, so, you have to do the planned
independent requirements reorganization as described in note 135807.
I hope this can help you !!!

Change UOM in Material master

Hi friends,
I have a material X in Plant ABC and Plant XYZ.
I have no open PR's and PO's for those materials.
I have received 10 Ea in Plant ABC on 10/20/09 ( Current stock is 10 ea in ABC)
                   and 20 Ea in Plant XYZ on 11/12/2009.( Current stock is 20 ea in XYZ)
Now I wanted to change the UOM from EA to LB.
I did issue (GM 201) 10 Ea from ABC and 20 Ea from XYZ. So, in MMBE no stock was showing.
Still, when i try to change UOM, it was erroring that "Stock exist in Plant ABC and Plant XYZ" ????
Any Idea, why so.
Appreciate your valuable feed back.
Note: I could change the UOM once I canceled the previous material documents to make sure Zero stock.
But, Why I could not be able to change when I issue (GM 201) and made zero stock????
Regards,
Dev.

Hi,
According to your explanation the condition has gone through as below scenarios:
You have received 10 Ea in Plant ABC on 10/20/09 ( Current stock is 10 ea in ABC)
and 20 Ea in Plant XYZ on 11/12/2009.( Current stock is 20 ea in XYZ)
You've issued 10ea in plant ABC on 11/23/09 (GM 201)
and you've I issued 20 ea in plant XYZ on 11/23/09 (GM201)
From the above, I conclude your current period is 11/2009 (November) and for solving the case on:
Plant ABC. --> cancel your GI (mvt 202) for 10ea with the same current date 11/23/09 then follow by
                        GI with the previous posting period 10/30/09
Plant XYZ --> display material stock with MM03 under storage location stock tab for previous period stock info.
                       then you should GI for relevant qty that you've seen onto previous period posting date.
Hope it may helps you...
Cheers,
Girang

Costing error while change mrp data in material master

Hi dears,

i need to change the mrp data in mm02 and i donot want to do delete the pcc .
any process to carryover
thanks
Edited by: raj on May 24, 2010 12:22 PM

Hi,
MRP is mainly configured for a material so that tere would not be any need for manual checking of the stock so as to create a PR.
The parameters which you have specified for a particular material like reorder point and lot size will help in planning for a particular material.
If you need only Qty of two (Less) then there s no need of configuring a MRP for that material
And lot size is also decided basing on certain other factors like
1) Lead time
2) Transportation costs involved in procuring the material etc
So ifyou want to generate PR for a qty of 100 then you need ot change the lot size
I hope this gives you clarity
Thanks & Regards

Restrict change authorization for MM17 (Material master mass maintenance)

Hi,
Apologies if I have posted this in the wrong forum. I want to know if it is possible to use the mass maintenance transaction MM17 (indus. material) to display data only istead of change/create. Is there some setting at the basis object level which can enable this? There are currently a lot of custom abap reports and queries in our system for viewing material master data, these can all be replaced by MM17. Basically we want to use MM17 as a reporting tool to display data only. Is a solution possible? Help is appreciated, thanks.
Regards

Have you tried the MM Information System node in the SAP Easy Access menu? There are a bunch of standard reports with navigation options there, for the user who has the correct authorization to display only.
Alternately, you may want to take a look into transaction MASS and use the B_MASSMAIN object, depending on your requirements - but test it well.
Cheers,
Julius

Error MM335 when trying to change profit center on material master record

We are trying to change the profit center that is assigned on the u201CSales: general/plantu201D tab in the material master (same as what shows on the u201CCosting1u201D tab of the material master).
The following error message appears: u201CYou want to change the profit center but there are still material stocks u2013 Message no. MM335.u201D
Our SAP version is SAP ECC 5.0 with support pack 19.
This particular material that we are trying to change only exists within one plant and one storage location in SAP.
I have done the following in order to try and resolve this issue:
1. Removed all inventory from the inventory management and warehouse management side for the material.
2. Closed all open purchase orders and process orders for the material.
3. Looked at the MD04 screen to verify there are no outstanding documents for this material.
I also searched for OSS notes and found note #1249513 which was applied to our sandbox environment. This note did not fix our problem.
I had a developer to debug the code that is being triggered upon making a profit center change. Two important pieces of information he found is that the SAP code is:
1. Looking to see if the u2018New G/Lu2019 is turned on and u2018profit centeru2019 is active in the new G/L.
2. Looking to see if previous period stock exists for the material.
The code is then setting a flag which causes the error message to appear.
I have found other comments in the forum stating to change the error to a warning for message MM335. I believe this is not the correct solution; as this would allow a change to a profit center even if stock exists, open orders exist, etc. I also know we could trick the system by temporarily changing the message to a warning and sending that through to production, changing the material master and following up with a transport to change the message back to an error. This would work, but we want a final resolution to this problem.
I believe that 2 OSS notes that were included in our latest support pack upgrade has caused this problem. Those notes are: 1057674 and 1106510.
I plan on opening a note with SAP, but was wondering if any users have experienced this same problem after a recent support pack upgrade.
Regards,
JH

Following is additional information regarding this problem. We were able to successfully change the profit center on some of our materials by making sure there was no stock in previous period and current period (and no open sales orders, purchase orders, etc.).

Change of UOM in Product Master with outstanding documents.

Hi all,
SRM allows the change of base UOM for product master even though there is outstanding document using that particular product master. Shouldn't it be the case whereby change of base UOM for product master is not allowed if there is outstanding documents?
Furthermore, I did a document check for the outstanding document and no error/warning message complaining that UOM in document does not match UOM as defined in product master. Any idea if this is correct?
Thanks.

hello weishan
i will check once again from my side and let you know shortly.
if you could change UOM in SRM master data , then it may not sync with ECC.
i think best practice master data change in source system and synchronise with srm system.

PP: Production Order Qty UOM should be based on the sales order Qty UOM though having Alternate UOMs in material master

Hello PP GURUS I am new to this and i have one issues. I.e., While creating the Production Order, want the unit in the production order should be based on the sales order unit instead of what has been defined in the material master. Since, having 3-4 alternate unit of a material & can create a Sales Order in any one of them.
Also pls let me how to go through
either with the help of ABAP or configuration.
If it is with the configuration pls let me know the solution to arrive.
Eg: Base UOM is KGS
Alt UOMs: SQM, MTR, NOS
Sale order is Prepared with SQM and the same shall be in production order too to produce qty.
Pls help me.
rgds,
Kumar V

Hi
First you have to maintain alternate units in mateial master for that first go in additional data & maintain the alternate units as below..
For example
1200 M2=1 KG For SQM
12 M=1 KG For MTR
3 PC=1 KG For NOS
And then you can get Sales unit field in sales data 1 view enter your sales unit in that field & you will get production unit in work scheduling views as per your desire production units and according to that units your sale order & production order will pick that units & you can proceed accordingly but remember that first maintian the conversion factor as above other wise it will not accept hope that it will help you have a nice day...

Reena
