SAP Material Management FAQ

Q: Is there any available SAP MM Configuration Books?

A: Currently, there is only one MM configuration books which can bought from Amazon :
The book title is : Instant Access: Sap Reference for Materials Management

Q: I have some other Materials Management question, where can I asked it?

A: Well, consider joining a MM forum.

Q: How can I extend all material to a new plant?

A: The SAP program - RMDATIND is used to create /update material master record.

Q: How can we delete materials permanently from Material master?

A: Use transaction MM70 - Material Master->Other->Reorganization->Material->Choose.
Build variant with selection range of material master records to be selected for deletion and maintain
run parameters.
Execute.
Use transaction MM71 - Material Master-> other-> Reorganizationn-->Material->Reorganization
Build a second variant
Maintain run parameters and execute.
It is also important to remove the records manually from info record, POs, PRs, reservation etc
for successful deletion of the material.

Q: SAP only provides moving average value for current, previous period, and previous year. SAP
does not provide transactions/reports that will provide moving average value for a given date.
How can I report moving average price for material number 10000000 at plant 0001 on July 4,
1998 .

A: Try any of these solutions:
1. Change the updating level of the structure (S031) to "daily". In LIS the total value and the total
stock are available. Divide value by the stock. It is possible to calculate this dynamically when
the analysis is run and to display the result.
2. Create your own structure in LIS and populate it by copying the Moving Average Price from the
material master every time there is a transaction. You will have data on those days when there
was a transaction.

Q: We have defined all the variables for the materials. However, when I attempt to use Material
Matchcode object MAT1, I get the response "No possible entries found". Why?

A: Matchcode i.d. "B", "Material by bill of material" has a selection condition for field STLNR NE ' '.
STLNR is the BOM number associated with a material in table MAST. Hence the message - "no
possible entries..." pops up if there are no bills of materials associated with your material numbers.
You get the matchcodes as long as the material referred by you has BOM number associated with
it.

Q: The matchcode object selection is defaulted to matctcode ID "B". Iwould like to change to M "
Material by Description" What is the solution?

A: Press the pull down arrow on the material number field and matchcode "B" is displayed, press
F5 double-click matchcode i.d. "M", then press F6 . This will set matchcode "M" as the default.

Q: We have one material master : X and the unit of measure is 'pcs' and two serial number : A,B
For this material we make two Pos
First PO calls material X , 1 pcs price 100 (will use serial number A)
Second PO calls material X , 1 pcs price 250 (will use serial number B)
Goods Receipt is done and by filling serial number for the fist PO with A and the second PO
with B.
We want to transfer material X serial number A to another plant and want the valuation of this
material as 100. How we can do it ?

A: Use "split valuation". Stocks may be received into separate storage locations. Transfer stocks may
be done from a storage location/plant to another storage location/plant.

Q: We want to change the calculation of Moving Average Price. We know that the same is in
MBEW-VERPR and two transactions to consider - MRHR, MB01. Is there a transaction to
change MAV or all the places it is needed?

A: Any Goods receipt or issue (in case of split valuated material) changes Moving Average price
depending upon the valuation type which is used when posting the goods issue. You have to go
through all the transactions involving those!
For Example:
Material X is using split valuation by origin:
Malaysia : MAV 60 USD - total stock 100 units
India: MAV 50 USD - total stock 200 units
Total stock 300 units MAV 53.33
Here , goods issues will also affect the global MAV, despite not changing MAV from origin
country.

Q: What is the use of configurable material.?

A: Configurable material is useful if you have a large number of combination of parts that go into a
product. It means different permutations and combinations of the parts for same material. If you
maintain a unique material code for each combination , you require a large number of material
numbers. KMAT may be used in such a case where you maintain just one generic product code.
A super BOM is maintained for such a material consisting of all possible alternatives. A routing is
also maintained consisting of all possible operations that could be used. Typically configurable
material is used in Made To Order (MTO) environment. However frequently ordered
configurations may be planned with a material variant which needs to have a material master record.
Thus Material variants may have stock and value. Depending upon characteristic values chosen at
sales order entry Sales Order BOM is created. Routing operations are also chosen depending upon
which BOM components are assigned to them.

Q: Will Source List automatically appear in Material Master as default if maintained at plant level
using OME5?

A: If you have maintained source list requirement in OME5 and have not maintained the source list
for the material. PO cannot be released. You are required to maintain source list for all materials
in the plant where the indicator is set if you maintain source list at plant level. Else you can make use
of info record to do so automatically.

Q: We have One company with a plant and another company with a sales organization. Which is better
option between these - PO or Stock Transfer Order ?

A: Cross company Stock Transport Orders can be done.

1. Configure using transaction OMGN.
2. Depending upon the sending and receiving plants, maintain sales organization and customer data

in customizing.
3. Maintain the supplying plant as a vendor and attach the plant to the vendor in the Vendor Master.
4. Material type has to be HALB or HAWA.
5. Ensure that the company with sales Organization has a plant to take care of stocking.
6. The PO used is NB and not Stock Transfer PO.
7. Configure SD for inter-company billing to enable picking up the pricing procedure for billing.
8. Carry Out delivery through process delivery due list and billing through process billing due list.

Q: We can make field mandatory. We want to make a default value to a Particular field in the Material
Master. Say, We want that the period indicator in the MRP2 view as "P". What is the best way?

A: Use transaction variant. Transaction SHD0 and then Transaction SE93.

SAP Workflow

Q: The following is set up for workflow:

1.Workflow organization Structure with 2 positions is created and assigned a person to both positions
2.Assign tasks to agent
TS 00007986 Requisition release - TO JOBS
TS 00008014 Purchase requisition release refused - GENERAL
TS 00008018 Requisition released - GENERAL
TS 00008348 Requisition release reset - GENERAL
WS 00000038 Workflow for purchase requisition release - TO JOBS
3.Activate event linkage
WS 00000038 Workflow for purchase requisition release
WE BUS2009 RELEASESTEPCREATE Purchase requisition Release step create is activated
4.Activated release codes for workflow

5.Assigned release codes to agent (JOBS created in 1)
The following error appears
"Work item 60772: Linkage to object BUS2009 event REJECTED cannot be written ".

A: Use transaction SWE2. Make sure "object BUS2009 event REJECTED" is enabled.
