In some industry sectors (for example, diary/meat,
pharmaceutical, chemical, steel, or paper industry sectors),
the
composition or attributes of products vary to some degree.
Therefore, you cannot use a fixed conversion factor to
convert quantities of these products into various units of
measure. Instead, each batch has to be given an individual
conversion factor.
The weights can vary from piece to piece, either due to
biological variations or because of weight loss during storage.
This variability should not be lost by using fixed conversion
factors, because this would mean that many business
processes would be based on incorrect values.
In SAP such process can be mapped by two ways
Batch-Specific Units of Measure
Catch Weight Management - IS-CWM Functionality
This document will give you some light on these SAP
functionalities.
1.CatchWeightwithBatch-SpecificUnitsofMeasure
Customization Requirement
Create No Dimensions Unit of Measurement
Create two no dimensions units LBI and CS/LB. LBI will represent
as Batch Specific Unit of measurement which will
assigned to its original unit of measurement i.e. LB (Pounds).
CS/LB is a no dimension unit which will be used to
define fraction between cases (CS) and Pounds (LB).
Click on Unit of measurement to create units LBI and CS/LB.
Please refer the screen below.

http://scn.sap.com/docs/DOC-43637 2/16
Maintain the details of LBI and CS/LB as per the above
screen.
Activate Batch Specific Unit of Measurement
The batch-specific material unit of measure is an alternative
unit of measure of a material, for which base unit of
measure can be defined on a batch-specific basis.
While the conversion ratio for other alternative units is
predefined in the material, for batch-specific material units
of
measure, we define:
The planned conversion in the material
The actual conversion ratio to the base unit of measure for the
batch.
-
4/1/2014 Catch Weight Management | SCN
http://scn.sap.com/docs/DOC-43637 3/16
Batch-specific material units of measure are used when the
conversion ratio for the unit of measure to the base unit
may vary for different batches of a material.
In this case, Base unit of measure is CS (Case) and valuation
unit is LBI (Pounds). Planned conversion ratio between
these units is defined in the material master, but actual
conversion ratio varies batch to batch which may depend on
the environmental factors.
To control these situations in SAP, we need to activate
Batch-Specific material units of measure.
We need to activate batch specific UOM as per the above
screen.
Define Batch Specific Unit of measurement
Create a Batch specific UOM.
We need to execute process step as mentioned above.
Click on New Entries in the screen above to define batch
specific UOM.
Define the Batch Specific UOM and linked it with actual UOM.
Here LBI is batch specific UOM which is linked to actual
weight unit (dimension Mass) LB.
Define Calculation of Proportion quantity from Base Quantity
Define the ratio of the proportion unit to the base unit. This
ratio is needed to convert base units to
-
4/1/2014 Catch Weight Management | SCN
http://scn.sap.com/docs/DOC-43637 4/16
proportion units of measure.
Click on New Entries in the screen above to define calculation
of proportion/product quantity from base quantity.
As per screen above, we have linked batch specific UOM with base
unit of measurement.
Define Calculation of Base Quantity from Proportion quantity
Define the quantity calculation with reference to base unit of
measurement.
Here we have defined CS and LBI calculation for no dimension
unit CS/LB.
Define attributes of system messages
We need to maintain message XU-033 as information message. In
standard SAP, this message would set to error
message. Please remove message category E and set as blank.
In standard SAP, fraction between two units of measurement is
set till two decimal points. If fraction value is defined
for three or more decimal value, then system will issue this as
error message XU-033.
In our case, we need are considering fraction value till five
decimal points, so that we can get more accurate values
after conversion. Take the following case:-
Number of Cases 10
Catch Weight
(LB)
39
Ration (CS/LB) = 0.26 when only two decimal allowed
Ration (CS/LB) = 0.25641 when five decimal allowed
From the calculation above, its clear that we would get more
accurate result when we go for higher decimal points.
So as per the screen below, we have changed error message
category to blank.

Master Data Requirement:
Create following master data for catch weight management,
Create Characteristics CT04
Create three characteristics. One characteristic will store the
actual fraction between number of cases and actual
catch weight. So we have characteristics CATCHFRACTION,
CATCHWEIGHT and NUMCASES to create. We need
to call CT04 transaction code to create these characteristics in
SAP.
Below mentioned screen shots will tell about the properties of
these characteristics.
Above screen tells about CATCHFRACTION property.
Above screen tells about CATCHWEIGHT property.
-
4/1/2014 Catch Weight Management | SCN
http://scn.sap.com/docs/DOC-43637 6/16
Above screen tells about NUMCASES property.
Maintain Dependency
Dependency will be used to calculate the fraction between number
of cases and actual catch weight. Call SAP
transaction CU01 to create dependency.
Create Class CL01
Create class for catch weight material. We need to assign all
characteristics as mentioned above Important thing to
note is that organization area in the class must be equal to S.
Call CL01 to create class and assign the
characteristics.
-
4/1/2014 Catch Weight Management | SCN
http://scn.sap.com/docs/DOC-43637 7/16
Assign Characteristics to Batch Class
Assign characteristics to class CL01
See the screen above for characteristics assignments. We must
put Organizational Area equal to S against the
characteristics which will be used for CS/LB conversion.
Maintain Material Master MM02
Assign the catch weight class to material master classification
view and update other parameters in the material
master. please see the screen below to know about various
important data in material master.
Select the additional data information in the material master
and click on the proportion/prod unit tab to maintain
planned conversion factor.
-
4/1/2014 Catch Weight Management | SCN
http://scn.sap.com/docs/DOC-43637 8/16
Maintain the planned conversion value into plan value as per the
screen below.
Valuation category of material must be equal to X.
Create vendor Info record
Maintain the vendor info record for batch specific UOM.
Price are maintained at batch specific UOM.
Transaction Data:-
Receiving actual CW at the time of MIGO
Create Purchase Order
Use ME21N transaction to create Purchase Order. Here we are
using material 69 for which Batch specific UOM is
active.
-
4/1/2014 Catch Weight Management | SCN
http://scn.sap.com/docs/DOC-43637 9/16
Perform goods receipt (MIGO)
We need to enter actual CW and GR quantity in the classification
view as,
Display Stock (MMBE)
Here we can see that, inventory is as per actual CW. System is
showing actual CW for the batch GR.

2.CatchWeightManagementIS-CWMFunctionalityIS-CWM is the
industrial solution developed by SAP AG The term Catch Weight
materials or CW materials for short,
is used for materials with variable weight.
Catch weight management business scenario has variants across
process such as
(a) Procure to Pay
(b) Order to Cash
(c) Manufacturing
(d) Inbound and Outbound Logistic
(e) Inventory Controlling & Accounting
1. IS-CWM enables use of one UOM in Logistics and another UOM
suitable for Financials and Controlling for the
same material.
2. Relationships between the two UOMs can be variable and
defined in the material master.
3. Goods movement can be recorded in both UOMs base unit of
measurement as well as parallel unit of
measure.
4. The valuation UOM can be either the Base UOM or the parallel
UOM this can be specified in the material
master.
5. CWM is based on a new Architecture comprising of
a) LIME Lean Inventory Management Engine Enables recording and
reporting of Inventory in different
UOM.
b) Inventory Accounting Enables postings with new valuation UOM
in FI and CO.
The fullfilment of purchase orders can be recorded and
controlled more accurate for catch-weight materials. While
posting goods receipt it is possible to post quantity in two
different unit of measure.
For inventory, the logistics unit of measure (UOM e.g. EA ) and
parallel unit of measure (e.g. KG)
Good Receipt MIGO
Same way it can be used for production/process order good
receipts, posting of goods receipt is possible to post
quantity in two different unit of measure EA and KG.
Stock Overview
You can view the stock in both the unit of measurement i.e; in
Base unit of measure and Parallel unit of measure.

Material consumption in PI Sheet with CWM
The goods issues and goods receipts related to process or
production orders can be recorded and controlled more
accurate for catch-weight materials. All movements are posted in
two units of measure (UOM) & parallel unit of
measure
Delivery
In the sales order the price is calculated based on sold number
of Kilo, number of Each is charged. The actual weight
is assumed to be entered into the Net weight field in the
delivery document.

Hi Rupesh, informative document. CWM will help to manage
variable conversion factor between base & parallelUoM for a
batch / HU, how will it be able to address weight loss process
?e.g. if I have CWM materialfor which I have posted GR (1 PAL = 350
kg = EUR 500). Over the period, the weight of this pallet isreduced
to 325 Kg due to evaporation losses. So from quantitative
perspective I have to reduce qty ofthis pallet but valuation should
not change i.e. I now need 1 PAL = 325 KG = EUR 500). How will
Imanage this qty variation ? Of course material is Valuated, so
physical Inv will result in accountingentry as well
