Variable size

So
boolean is 1 byte
byte is 1 byte
short is 2 bytes
int is 4 bytes
long is 8 bytes .
How many bytes are float and double?
How many bytes has a pointer?
Can I look this up somewhere on this website or in the documentation? I have not found it.
Is there any way to find out how large a certain object is?
About boolean: AFAIK 1 is true and 0 is false. What about numbers other than 1 and 0? Will all numbers unequal 0 turn out to true, or will (binary) numbers ending in 0 be false and those ending in 1 be true? Not that it really matters, as one cannot convert booleans to numbers or v.v. in Java.

There is no such thing as a pointer in Java.Yes, there are, there is just no pointerarithmetic.
I still have to disagree with you. they r called
as reference and not pointer. pointers r really
different from references.I think pointers and references are the same. What is
the difference?From the index to the language specification
pointers
See references
Also from the Language Specification 4.3.1 http://java.sun.com/docs/books/jls/second_edition/html/typesValues.doc.html#9317
An object is a class instance or an array.
The reference values (often just references) are pointers to these objects, and a special null reference, which refers to no object.
Seems to say that references and pointers are the same thing.

Variable Size Error.

Hi Experts,
I am using a variable to get the error message and use that in sending mail, but when i ran the scenario its error out saying,
"ORA-12899: value too large for column".
My assumption is when the error message exceed more than 200 characters its error out. So my question is how to increase the size of the variable size?
Please help..
Thanks

Variable size item problem in BOM

hi all,
We have semi-finished material with componets as variable size items (item cat. R)
Now in the variable size tem data, Size 1 = 1,406 MM, Size 2 = 1,220 MM. Numner is 1 ST, formaula place is blank.
Qty Var-Sz Item is calculated by system is 3.957 M2. On what basis this value is calculated?
In the component material we have maintained a componenet scrap quantity as 15%.
BOM ratio of header : component = 1NOS : 1 ST
Again when we create a production order for the header, for 1 NOS header quantity component qty becomes 2.
For 2 NOS of header qty, component becomes 3 like this.
Why this happens..
Regards,
Srijit.

Variable size item:

Hi
Company procures copper sheet of certain thickness with different sizes. Stock keeping dimension is KG. Material master has alternative unit of measure and conversion factor for KG and cubic centimeter. Design department will enter this sheet dimension like 15005003 in BOM and it will correctly calculate KG with formula entered.
My problem is shop floor person will come to know the dimension and KG relation but how store person will come to know what size he has to cut and issue against production order. As while issuing goods he can only see quantity in KG and not in cubic centimeters ?

SDBSAP ,
If its unanswered why you flaged it answered .......?
and solution to your problem in standard sap is not possible.
You need to go for development, logic can be , for all variable size items from a BOM you need to pick size 1 size 2 and size 3 to print on issue slip . It will give exact dimension to your storage person to issue the correct dimension sheet to shop floor.

Variable size items.

Hi, im a PP consultant from bombay, i had a query regarding a client who is inti\o wooden frame manufacturing it is a strictly discrete industry and the client specifications vary with almost every request. at the moment the client is creating a new mat master for every new product thus causing the master materials to run into 50-60 thousand currently. i want to know if i can use variable size items to reduce the number of materials defined as all of the materials are from standard sized planks. stock is required to be maintained for all components individually.

Hi,
"If you want different-sized sections of a material (raw material) to be represented by one material number in BOM items, you use this item category."
Ans lies in the your last statement(stock is required to be maintained for all components individually)You cannot go for variable size item as you need to maintain stock individually

Variable size item formulla key funtion module,

I am developing user interface for manual reservation (cutsom development). User wants to calculate quantity of material if he enters size1, size2 and size3. Also he wants that a formula key option to be provided so that he can mention conversion formula. Is there any standard function module for variable size formulla funtion module.
I want to use same logic of variable size item formulla of bom in the above custom template.
Please suggest.

Hi
The function module EVAL_FORMULA and FORMULA_EVALUATION may help you as they all export calculated values as output. Please go to SE37 to click the button 'Function module documentation' to see more information.
Or go to SE80 to check the function group CALC to see more function.

Variable size item Vs Stock item

Hi Experts,
I have a doubt regarding the use of variable size item over standard stock item. I will give an example as under.
I have an item called cable which is to be added to a header material. This cable will be used in many header materials. I tried using variable size item as an item category and given the following parameters
Size 1 as 5 M(UOM)
Formula (L1)
Number (1) ST
System calculates the value as 5 M for qty var sz item
In the item over view screen, quantity against the material 1 ST
My query is instead of giving the qty as 5 M and use a formula, what if i directly give the item as stock item "L" and directly define the qty as 5M. If there is no difference between the above, why should we use the variable size item? instead we can directly calculate and give the qty for the item right. Kindly clarify the application of variable size item over standard stock item category.
In both the cases I will be having one material code in the system and the qty will be changed in the respective BOM of two different header materials.
Regards,
Sridharan M

Hi
In addition to the stock keeping unit you can provide the details like length, width and thickness, say for example if you want to fabricate a metal part. You may need length width and thickness of the plate to be used for fabrication. This details you will be entering in the variable size items and using the formual you can calculate the required quantity in KG.
This kind of variable size items you need not calcualte the weight of the material you just need to enter the sizes as per the drawing as you prepare the BOM.
This varies with respect to size.... Variable Size Items

Variable size material assigning problem

Hi friends,
I am trying to assign a variable size material for an activity. There is a scenario in which they are giving only one dimension and no formula is been used to calculate but the required qty field is rounding off for next decimal point for eg: if the size of material i am giving as 0.912 mm then the required qty is round off to 0.920. Can any one please tell me do we have any config setting to be done to take out this rounding off decimal point.
Thanks
Satish.

the data element for required quantity CO_MENGE has 3 places of decimal - so basically it should be fine
I have checked in my system and I can see 0.912 for a material with dimension length
the other thing is check the material master - additional data for units of measure - or there might be some program rounding off the units to 2 digits
If you are using a custom unit then check CUNI and make sure it is not set to 2 decimal places

Variable size array in a FlowPane

If i have an array of variable size (for example a array of cards).
How can i build something to show the elements(in a FlowPane for example) and each of them having its own controller (fxml + controller for each card), so the container (flow pane) of the elements (cards) can have it's elements swaped, removed or added new ones?
Controller:
public class HandController extends FlowPane implements Initializable{
    @Override public void initialize(URL arg0, ResourceBundle arg1){
    public void setHand(ArrayList<Cards> Hand){
        //this would work if the hand were static
        for(int i = 0; i < Hand.size(); ++i){
            FXMLLoader fxmlLoader = new FXMLLoader(getClass().getResource("CardView.fxml"));
            CardController controller = new CardController();
            fxmlLoader.setController(controller);
            fxmlLoader.setRoot(controller);
            Parent card = (Parent)fxmlLoader.load();
            fxmlLoader.setRoot(card);
            this.getChildren().add(card);
            controller.setCard(Hand.get(i));

Well, I was bored...
This "game" has a hand of up to five cards. You can deal from a deck to the hand, and then play (or discard) a card by double-clicking on it.
The model comprises a Card class, a Deck class, and a GameModel class. The last one tracks the hand and deck and the relationship between them. Card and Deck were written from my memory of reading an example of using Enums by Josh Bloch.
Card.java
package cardgame;
public class Card {
     public enum Rank {
          Ace, Two, Three, Four, Five, Six, Seven, Eight, Nine, Ten, Jack, Queen, King
     public enum Suit {
          Clubs, Diamonds, Hearts, Spades
     private final Rank rank;
     private final Suit suit;
     public Card(Rank rank, Suit suit) {
          this.rank = rank;
          this.suit = suit;
     public Rank getRank() {
          return rank;
     public Suit getSuit() {
          return suit;
     @Override
     public String toString() {
          return String.format("%s of %s", rank, suit);
     @Override
     public int hashCode() {
          final int prime = 31;
          int result = 1;
          result = prime * result + ((rank == null) ? 0 : rank.hashCode());
          result = prime * result + ((suit == null) ? 0 : suit.hashCode());
          return result;
     @Override
     public boolean equals(Object obj) {
          if (this == obj)
               return true;
          if (obj == null)
               return false;
          if (getClass() != obj.getClass())
               return false;
          Card other = (Card) obj;
          if (rank != other.rank)
               return false;
          if (suit != other.suit)

     public static Deck newDeck() {
          return new Deck();
     public static Deck shuffledDeck() {
          return newDeck().shuffle();

               throw new IllegalStateException("Hand does not contain " + card);
}The CardController is the controller for a CardView. It takes a reference to a Card and its initialize method initializes the view to display it (the view is just a simple label).
CardController.java
package cardgame;
import javafx.fxml.FXML;
import javafx.scene.control.Label;
public class CardController {
     private final Card card;
     @FXML
     private Label label;
     public CardController(Card card) {
          this.card = card;
     public void initialize() {
          label.setText(String.format("%s%nof%n%s", card.getRank(),
                    card.getSuit()));
}The HandController is the controller for the display of the hand. This is where most of the action happens. The trick here is that it requires a reference to a GameModel, which needs to be injected from somewhere, so we need a setModel(...) method, or something similar. I didn't want to assume the order of events: i.e. whether the model is injected before or after the initialize() method is invoked. To keep this flexibility, I used an ObjectProperty to wrap the model, and listen for changes to it. When the model is updated, I register a listener with the hand (exposed by the model). This listener in turn rebuilds the views of the cards when the hand changes. There's also a "deal" button, whose disabled state is managed by binding to a property in the model (using a neat trick from the Bindings class to allow the model value to be dynamic).

Variable size material

how we create variable size material
thanks in advance

Dear,
T-Code-CS01
1. Enter the material for which you want to create BOM, Plan and BOM usage.
2. Select the item category "R", enter the component. Now you will be taken to the "Variable item data" screen.
3. Enter the datas of Size 1, 2 & 3 (as required) and the unit of the size & number. System will calculate the "Qty of var- size item" in the unit assigned to the basic data of the material master of the component.
4. Save
You can change the unit of the variable size item as per your requirement in OS28

Storage location selection for variable size item

Hi All
There is a BOM of finished good Material "XYZ" and there is a component "A" in the BOM. This Component A is a variable size item, its a metallic bar of length 4 meters. In BOM XYZ, only 1.5 meters is consumed.
Now when a production order is made for XYZ and the confirmation is done with movement type 261. All the materials are backflushed along with component A . The client's requirement is to transfer the remaining length of component A (i.e. 4 - 1.5 = 2.5 meters ) to a different storage location at the time of confirmation.
Please let me know how is it possible.
Thanks in Advance

1.first do mb1b 311 mvmt transfer posting for the components from raw-stor location to prod stor location. you can do for A
2. do GI for the components. for A for that final product . consume 1.5 so. the remaining component will be (3 ) there in the stor. location as per sap. (check in mmbe)
3. then do mb1b 311 transfer posting for the A component to raw-stor location. from the prod stor location.
or rever the transfer posting mb1b 312.

Reqmt qty of variable size item in purchase requisition

Hello All
I am having a FG "A" & components "B" & "C" out of these two components "B" is variable size item with Base UOM as M, I have given two sizes of "B" as 3M & 2M in the BOM., i.e. material "B" is added two times as a component with variable size item.
For 1SQM of A" require 3M & 2M of "B" & 1KG of "C". When am having a reqmt of 10SQM of "A" the sys calculates the dependent reqmt correctly as 30M, 20M of "B" & 10KG of "C", but the purchase requisition of "B" is coming as of 50M.
My problem here is that how the user would come to know how many qty of "B" is reqd of 3M & 2M length.
Please throw some light on this behavior of the system. Looking forward to your valuable inputs & guidance.

J K Tharwani

jitendra,
as i post in my earlier reply ,
there is one work around which will work for you is that , use lead time offset ( with positive + or negative quantity of day ) in component detail screen for one of the position of B in the BOM so in that case you will have 2 different purchase requisition for B.
Check it out and revert back , i am sure it will work for you.
Only problem is the date will be delayed by one day or prepone by one day for the second position where B is assigned.
other wise there for getting this information in PO , you need to go for Z development.
for it you need to keep a check on specific plant , what are the purchase requisition that have material which are being used as variabble size item category in BOM and for this material you need to Pull values from Variable size field of Item, details screen.
ROM1 and ROM2 and publish it in text of PR and PO.
Check and revert back.

Variable size item scenario.

Hi,
Requirement: A single material code should be used for a sheet metal for a specific thickness. Different shapes will be cut from the main sheet and to be identified with the same code but with various dimensions.
Also to be identified in the system the balance material available, stocking with different batch quantities sales order wise.
can anyone explain how to map the above scenario in SAP with detailed steps.
Best Regards
Vijay.

Hello

1)while creating the master mention the material group as ur material code. in basic data 1
2) in classification view maintain class 023 batch class & mention the variable size of ur product,so when u create the bach u can mentain ur chara values as required.

Hi Raghu,
1. Maintain KG as BUM in material master for the component
2. Maintain alternative unit of measure for volume (meter Cube) and BUM (KG)
3. Maintain Default values for BOM in configuration (T-Code OS28) for Variable Size item as EA
4. Maintain Formula key in configuration (T-Code OS15) for the formula to be used ie ROMS1 8 ROMS2 * ROMS3 * 1160
5. While creating BOM give Item category as R for the component and give the qty, the system will pop up a screen for variable sizes. Enter Variable sizes.
Hope the above satifies your requirement.
Please try and revert back
Regards
