Catch Weight Management

In some industry sectors (for example, diary/meat, pharmaceutical, chemical, steel, or paper industry sectors), thecomposition or attributes of products vary to some degree. Therefore, you cannot use a fixed conversion factor to convertquantities of these products into various units of measure. Instead, each batch has to be given an individual conversionfactor.

The weights can vary from piece to piece, either due to biological variations or because of weight loss during storage. Thisvariability should not be lost by using fixed conversion factors, because this would mean that many business processeswould 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 MeasureCustomization Requirement

Create No Dimensions Unit of Measurement

Create two no dimensions units LBI and CS/LB. LBI will represent as BatchSpecific Unit of measurement which will assigned to its original unit ofmeasurement i.e. LB (Pounds). CS/LB is a no dimension unit which will be used todefine fraction between cases (CS) and Pounds (LB).

Click on Unit of measurement to create units LBI and CS/LB. Please refer the screen below.



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.



Batch-specific material units of measure are used when the conversion ratio for the unit ofmeasure 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). Plannedconversion ratio between these units is defined in the material master, but actual conversionratio varies batch to batch which may depend on the environmental factors.

To control these situations in SAP, we need to activate Batch-Specific materialunits 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 batchspecific 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 toproportion units of measure.



Click on New Entries in the screen above to define calculation of proportion/product quantityfrom 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 Eand set as blank.

In standard SAP, fraction between two units of measurement is set till two decimal points. Iffraction value is defined for three or more decimal value, then system will issue this as errormessage XU-033.

In our case, we need are considering fraction value till five decimal points, so that we canget more accurate values after conversion. Take the following case:-

Number of Cases 10Catch 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 resultwhen 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 fractionbetween number of cases and actual catch weight. So we have characteristicsCATCHFRACTION, CATCHWEIGHT and NUMCASES to create. We need to callCT04 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.



Above screen tells about NUMCASES property.

Maintain Dependency

Dependency will be used to calculate the fraction between number of cases and actual catchweight. Call SAP transaction CU01 to create dependency.



Create Class CL01

Create class for catch weight material. We need to assign all characteristics asmentioned above Important thing to note is that organization area in the classmust be equal to S. Call CL01 to create class and assign the characteristics.



Assign Characteristics to Batch Class

Assign characteristics to class CL01



See the screen above for characteristics assignments. We must putOrganizational Area equal to S against the characteristics which will be usedfor CS/LB conversion.

Maintain Material Master MM02

Assign the catch weight class to material master classification view and update otherparameters in the material master. please see the screen below to know about variousimportant data in material master.



Select the additional data information in the material master and click on theproportion/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.



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 whichBatch specific UOM is active.



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 thebatch GR.



2. Catch Weight Management IS-CWM Functionality

IS-CWM is the industrial solution developed by SAP AG The term Catch Weightmaterials 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 forthe 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 reportingof Inventory in different UOM.

b) Inventory Accounting Enables postings with new valuation UOM in FIand 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 differentunit 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 goodsreceipt 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 andParallel unit of measure.



Material consumption in PI Sheet with CWM

The goods issues and goods receipts related to process or production orders can berecorded and controlled more accurate for catch-weight materials. All movements are postedin two units of measure (UOM) & parallel unit of measure

Delivery

In the sales order the price is calculated based on sold number of Kilo, numberof Each is charged. The actual weight is assumed to be entered into the Netweight field in the delivery document.
