Query regarding MB1A transaction

Dear Gurus,
We are facing a situation where we are trying to scrap a material using the transaction MB1A. We are using movement type 551.
An outbound delivery has been created, but still the material intended to scrap is seen in unrestricted use only. Hence if we are creating any sales order for the material, the line is getting confirmed.
Request you to let us know whether material does not get allotted to outbound delivery, so that ATP stock becomes 0 at the time of outbound creation.
regards,
Krishna

Sorry.. Paraphrasing my question..
Hi All,
We are facing a situation where we are trying to scrap the available stock of a material using the transaction MB1A. We are using movement type 551.
An outbound delivery has been created, which is in status A( goods movement not yet started)
However if we are creating any new sales order for the material, the line is getting confirmed.
Request you to let us know whether material does not get allotted to outbound delivery, so that ATP stock becomes 0 at the time of creating another fresh sales order for the material after outbound creation.
Thanks in advance.

Krishna Mohan Gurajada

Query regarding SPAU Transaction Details

Hi,
This is regarding Upgradation Process.
We use SPAU transaction to list down all the SAP objects that got modified in the current system.
In this case, whether it lists the details of custom objects that are dependent on Standard SAP objects.
Thanks,
Udaya.

SPAU only gives you the standard SAP Objects that were modified using the Modification Assistant.. you can also use the Tcode SE95 to list out the objects before you actually start the upgrade... If its a custom Object, it will be left as is.. if the custom Object is a copy of a stda SAP Object, you will have to manually compare the custom Object with the latest std object and make the corresponding changes yourself..

Query regarding RF transaction

Hi,
Currently I am using Tcode-LM61 for picking and packing process for assigning handling unit to delivery docs.
I have 2 queries:
1) I knew that to pack /scan any material in warehouse, we need to use SU instead of HU.Kindly confirm on this.
2) Secondly If I use SU , does that mean that HU is not required to be maintained during delivery creation?
3) Thirdly kindly confirm the process-Order-Outbound delivery-Create transfer order ( with SU)- Pick and pack in outbound delivery ( using HU)- PGI.
4) Is it mandatory to have SU in warehouse if I am using handling unit management.
5) Last the settings we need to do to activate SU in warehouse?

It is purely a business decision, if you need to track the label through out the process like delivery, shipping and invoicing, then you can use HU.
SU is only used in WM, you can not use SU label in shipping or other processes.

You can also use Both system will create on SU for every HU

SU management will be activated in the Warehouse level and you can activate for each Storage type if required

Regarding CS03 transaction

Hi friends,
I have a simple query regarding the transaction CS03. When I give the Material Number, Plant and BOM Usage as input, I would get the list of components for this material.
Inside the transaction, is a CHECKBOX field ASM - this Indicates that the component for this material has its own BOM or has further components).
Could anyone tell me in which SAP table this information is stored i.e. an indicator to tell us if the component/material has further BOM or not.
I checked MAST and STPO tables but could not figure out the right field.
Awaiting your valuable inputs.
Thank You.
Regards,
Gayathri.

hi gayathri,
1.
the bom can exist for HALB or FERT .
u can dimnish the material not having a bom on this category .
i.e to say material type 'RAW' dosent hav a bom .
2.
like check out for table "MVKE" (Sales Data for Material) and in here check the fields
MVKE-MTPOS (Item category group from material master)MVKE-DWERK(Delivering Plant).
now giv the material and execute for initially dont giv a plant , and execute .
proceed with parent-matrial in bom and execute ,
u'll see the list of materials assigned in a particular sales area now check for MTPOS status this will have a category called LUMF ( this u will hav only for parent)
now say that the parent have 4 child materials (say)of which one has subassemblies so as u said it will hav a ASM check box ticked in CS03, now take this material and goto mvke and repeat the procedure and check the MTPOS status this will have item category like 'NORM'
remember for parent it was 'LUMF'
now for child(having subass;les) we got'NORM'
now check for same which dosent have a subassemblies from the child items it will be like 'ZATP' or 'XXXX' but not LUMF or NORM. to tell that it dosent hav further bom.
generalise the conclusion for all the materials(parent childorphans)if found okay apply this logic.
second alternative is ,
check the transaxction cs12.
give BOm material and observe that the first field(dglvl) ...
it indicates the level of that material in thta BOM.
exact indiaction is whether it has sub assemblies in that Material is the
field (BOMFL) If it has sub assemblies then it will be' X'.
see if u can make any hit in the tables using this relation above

Transaction variant for Goods Issue going back to MB1A transaction screen

Hello,
I have created a transaction variant ZMB1A for Goods issue.
When the goods issue transaction completed by using ZMB1A system again going back to the initial screen of MB1A. (Since it is the base of MB1A)
Here the issue is everytime user had to enter the ZMB1A transaction. (for example if the user wants to issue material for different plants).
Please suggest any suitable method to avoid the above multiple t code execution.
Regards
Rifaie M

Hi,
In SHD0, do the complete processing of Transaction MB1A during creation of Transaction Variant "ZMB1A" till posting of the Material document.
To create a new T-Code as ZMB1A, go to Transaction SE93 and here enter Transaction Code as ZMB1A and Click Create button. Now enter Short text of Transaction and select option "Transaction with Variant (Variant transaction)" and press enter.
Here enter following;
Transaction MB1A
Transaction variant ZMB1A
Activate "Cross-client"
Select Professional User Transaction
Activate SAP GUI for HTML
Activate SAP GUI for Java
Activate SAP GUI for Windows
Now Click SAVE button.
Now you can start using Transaction ZMB1A which will call Transaction Variant ZMB1A.

Query regarding Check Printing

Hi All,
I have a query regarding check Printing.
Once I am printing the Check with Transaction FBZ5, the roller of the printer is not being stopped after the printing of first check and four to five checks are coming out.But I want one check will print in the first print command and marker should come onto the edge of second check.
please suggest how we can do it..
Thanks,
Rajeev

Hi!
Make a runtime analysis (SE30) and try to find the slow parts. Maybe there is not much help, because it's also possible that the printer needs so much time to convert the data.

database
and displays this data in a Front End GUI.
2. Now,I make a change in my Java application by
adding new elements to the same row.This row now
contains additional XML elements.
I would like to display the new row with the new
elements in the GUI.
What is a better option for doing the above?
1.Delete the row being shown,save the new row with
the changes in the database,and re display it?
2.Or,Update the row dynamically and refresh?
Any suggestions
Thanks,If you delete (it seems to me yours this process is regular and frequent) and re insert the new updated one record then High water mark will cause to scan yours table which may cause to degrade the performance.AFAIK you should go with update.But hold down dont implement it as i suggested lets see what are others solution here which may be more precious then mine.

A query regarding synchronised functions, using shared object

Hi all.
I have this little query, regarding the functions that are synchronised, based on accessing the lock to the object, which is being used for synchronizing.
Ok, I will clear myself with the following example :
class First
int a;
static int b;
public void func_one()
synchronized((Integer) a)
{ // function logic
} // End of func_one
public void func_two()
synchronized((Integer) b)
{ / function logic
} // End of func_two
public static void func_three()
synchronized((Integer) a)
{ // function logic
} // End of func_three, WHICH IS ACTUALLY NOT ALLOWED,
// just written here for completeness.
public static void func_four()
synchronized((Integer) b)
{ / function logic
} // End of func_four
First obj1 = new First();
First obj2 = new First();
Note that the four functions are different on the following criteria :
a) Whether the function is static or non-static.
b) Whether the object on which synchronization is based is a static, or a non-static member of the class.
Now, first my-thoughts; kindly correct me if I am wrong :
a) In case 1, we have a non-static function, synchronized on a non-static object. Thus, effectively, there is no-synchronisation, since in case obj1 and obj2 happen to call the func_one at the same time, obj1 will obtain lock for obj1.a; and obj2 will obtain lock to obj2.a; and both can go inside the supposed-to-be-synchronized-function-but-actually-is-not merrily.
Kindly correct me I am wrong anywhere in the above.
b) In case 2, we have a non-static function, synchronized on a static object. Here, again if obj1, and obj2 happen to call the function at the same time, obj1 will try to obtain lock for obj1.a; while obj2 will try to obtain lock for obj2.a. However, since obj1.a and obj2.a are the same, thus we will indeed obtain sychronisation.
Kindly correct me I am wrong anywhere in the above.
c) In case 3, we have a static function , synchronized on a non-static object. However, Java does not allow functions of this type, so we may safely move forward.
d) In case 4, we have a static function, synchronized on a static object.
Here, again if obj1, and obj2 happen to call the function at the same time, obj1 will try to obtain lock for obj1.a; while obj2 will try to obtain lock for obj2.a. However, since obj1.a and obj2.a are the same, thus we will indeed obtain sychronisation. But we are only partly done for this case.
First, Kindly correct me I am wrong anywhere in the above.
Now, I have a query : what happens if the call is made in a classically static manner, i.e. using the statement "First.func_four;".
Another query : so far we have been assuming that the only objects contending for the synchronized function are obj1, and obj2, in a single thread. Now, consider this, suppose we have the same reference obj1, in two threads, and the call "obj1.func_four;" happens to occur at the same time from each of these threads. Thus, we have obj1 rying to obtain lock for obj1.a; and again obj1 trying to obtain lock for obj1.a, which are the same locks. So, if obj1.a of the first thread obtains the lock, then it will enter the function no-doubt, but the call from the second thread will also succeed. Thus, effectively, our synchronisation is broken.
Or am I being dumb ?
Looking forward to replies..

a) In case 1, we have a non-static function, synchronized on a non-static object. Thus, effectively, there is no-synchronisationThere is no synchronization between distinct First objects, but that's what you specified. Apart from the coding bug noted below, there would be synchronization between different threads using the same instance of First.
b) In case 2, we have a non-static function, synchronized on a static object. Here, again if obj1, and obj2 happen to call the function at the same time, obj1 will try to obtain lock for obj1.a; while obj2 will try to obtain lock for obj2.a.obj1/2 don't call methods or try to obtain locks. The two different threads do that. And you mean First.b, not obj1.b and obj2.b, but see also below.
d) In case 4, we have a static function, synchronized on a static object. Here, again if obj1, and obj2 happen to call the function at the same time, obj1 will try to obtain lock for obj1.a; while obj2 will try to obtain lock for obj2.a.Again, obj1/2 don't call methods or try to obtain locks. The two different threads do that. And again, you mean First.b. obj1.b and obj2.b are the same as First.b. Does that make it clearer?
Now, I have a query : what happens if the call is made in a classically static manner, i.e. using the statement "First.func_four;".That's what happens in any case whether you write obj1.func_four(), obj2.func)four(), or First.func_four(). All these are identical when func_four(0 is static.
Now, consider this, suppose we have the same reference obj1, in two threads, and the call "obj1.func_four;" happens to occur at the same time from each of these threads. Thus, we have obj1 rying to obtain lock for obj1.aNo we don't, we have a thread trying to obtain the lock on First.b.
and again obj1 trying to obtain lock for obj1.aYou mean obj2 and First.b, but obj2 doesn't obtain the lock, the thread does.
which are the same locks. So, if obj1.a of the first thread obtains the lock, then it will enter the function no-doubt, but the call from the second thread will also succeed.Of course it won't. Your reasoning here makes zero sense..Once First.b is locked it is locked. End of story.
Thus, effectively, our synchronisation is broken.No it isn't. The second thread will wait on the same First.b object that the first thread has locked.
However in any case you have a much bigger problem here. You're autoboxing your local 'int' variable to a possibly brand-new Integer object every call, so there may be no synchronization at all.
You need:
Object a = new Object();
static Object b = new Object();
