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. Catch Weight with Batch-Specific Units of Measure 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

Catch Weight Management | SCN
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.
http://scn.sap.com/docs/DOC-43637

Catch Weight Management | SCN
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.

Catch Weight Management | SCN
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 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, it’s 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.
http://scn.sap.com/docs/DOC-43637
5/18
12/11/2014
Catch Weight Management | SCN
Above screen tells about ‘CATCHWEIGHT’ property.
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.
http://scn.sap.com/docs/DOC-43637
6/18
12/11/2014
Catch Weight Management | SCN
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.
Assign Characteristics to Batch Class Assign characteristics to class CL01
http://scn.sap.com/docs/DOC-43637
7/18
12/11/2014
Catch Weight Management | SCN
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.
Maintain the planned conversion value into ‘plan value’ as per the screen below.
Valuation category of material must be equal to ‘X’.

Display Stock (MMBE) Here we can see that, inventory is as per actual CW. System is showing actual CW for the batch GR.
2. Catch Weight Management – IS-CWM Functionality IS-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 UOM’s can be variable and defined in the material master.
http://scn.sap.com/docs/DOC-43637

3. Goods movement can be recorded in both UOM’s – 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

Hi Rupesh, informative document. CWM will help to manage variable conversion factor between base & parallel UoM for a batch / HU, how will it be able to address weight loss process ?e.g. if I have CWM material for which I have posted GR (1 PAL = 350 kg = EUR 500). Over the period, the weight of this pallet is reduced to 325 Kg due to evaporation losses. So from quantitative perspective I have to reduce qty of this pallet but valuation should not change i.e. I now need 1 PAL = 325 KG = EUR 500). How will I manage this qty variation ? Of course material is Valuated, so physical Inv will result in accounting entry as well Like (0)
Oscar Morales-Bello Sep 19, 2014 5:04 PM (in response to Amol Palsodkar)
What I've seen done in the past is create a custom program that: -Captures the new weight of the product X -Creates a Process Order with product X as both "a material and a finished product." -Goods issue the old weight against the process order -Goods receive the new weight against that same process order -Posts/Confirm/Closes/Settle or whatever you call the final activity of the Process Order As you should already know, the Process Order itself will calculate and update the cost for the new weight of its finished product.
