Find the exact difference between 2 layers

I have a question:
I have 2 photos, exact the same position, light, color etc. the only difference, in one of them is i.e. a person (the other one could be described as an empty background plate).
what do I have to do to get a selection of what pixels are identical between the 2 photos, so I can invert that selection and can isolate the person?
(the usual suspects, difference, subtract etc don't do the trick, converting both to a smart object and then going through the stack modes also doesn't result in anything that resembles a clean mask).

Hello!
I would superpose the images, set the top one to the Subtract blending mode. Maybe use levels to push the whites to the left, then create a channel out of it.

What's the exact difference between "Query Def. Filter Value Selection" and

Hi Gurus,
what's the exact difference between "Query Def. Filter Value Selection" and "Query Execution Filter Val. Selectn" in info-object's "Business explorer" tab?
I found out that if my info-object A has a input-ready variable in a query,after the query running,in the selection screen,my info-object A's F4 value is follow the setting of "Query Execution Filter Val. Selectn",as the setting of "Query Def. Filter Value Selection" I tried every diff setting, it won't effect my query anyway.
so:
1.what's the exact difference between "Query Def. Filter Value Selection" and "Query Execution Filter Val. Selectn" in info-object's "Business explorer" tab?
2.how they effect query's presentation?
I searched forum,didn't find the answer what I want.
Thanks everyone.

Hi Denny,
I will try to explain it again.
Query Def. Filter Value Selection : Let say the value is set to "Only Values in Infoprovider"
Lets take an example infoobject - 0MATERIAL (Material)
Total material records in material Master = 1000 (master Data table /BI0/PMATERIAL)
You create a query on top of an Infoprovider using Material.
Total unique materials in Infoprovider= 500.
Now when you are in design mode in Query Designer, and you try to restrict Material by few materials (for e.g. 1, 2, and 3), for this you right click on material and select Restrict, the pop-up opens with list of materials, this list is all those 500 materials which are in the infoprovider, because the setting is "Only Values in Infoprovider". Which means then when you are trying to restrict a characterstic in query definition the list of values displayed for restricition is derived from Infoprovider.
Query Execution Filter Value Selection - I think you already know what it is , its the read mode for F4 help selection.
I hope this helps.
Thanks

you could try something similar to this, for each table pair that you want to compare:
SELECT 'TABLE_A has these columns that are not in TABLE_B', DIFF.*
FROM (
        SELECT COLUMN_NAME, DATA_TYPE, DATA_LENGTH
          FROM all_tab_columns

What is the exact difference between Database Cloning and Database Refresh?

Hi,
Can anybody tel me the exact difference between Database Cloning and Database Refresh?
I Have some conflicts in these topics.
Thanks
Rajesh

Refresh is what it says, "refresh" . You have a main site which would always have the data being inserted into it. There would be another site which would remain some where else . This site needs to be refreshed with the primary site. So you need to do export from the primary, push it to the secondary site and done!

Wat is the exact differences between clustered table and pooled table

hi,
can you tell me ravi...wat is the exact differences between clustered table and pooled table
with regards//
anilreddyg

Hi Anil Reddy
Pooled Tables, Table Pools, Cluster Tables, and Table Clusters
These types of tables are not transparent in the sense that they are not legible or manageable directly using the underlying database system tools. They are managed from within the R/3 environment from the ABAP dictionary and also at runtime when they are loaded into application memory.Pool and cluster tables are logical tables. Physically, these logical tables are arranged as records of transparent tables. The pool and cluster tables are grouped together in other tables, which are of the transparent type. The tables that group together pool tables are known as table pools, or just pools; similarly, table clusters, or just
clusters, are the tables which group cluster tables.Not all operations that can be performed over transparent tables can be executed over pool or cluster tables.
For instance, you can manage these tables using Open SQL calls from ABAP, but not Native SQL.These tables are meant to be buffered and loaded in memory, because they are commonly used for storing internal control information and other types of data with no external (business) relevance. SAP recommends that tables of pool or cluster type be used exclusively for control information such as
program parameters, documentation, and so on. Transaction and application data should be stored in transparent tables.
Table Pools
From the point of view of the underlying DBMS as from the point of view of the ABAP dictionary, a table pool is a transparent table containing a group of pooled tables which, when created, were assigned to this table pool.
Field Type Description
TABNAME CHAR(10) Table name
VARKEY CHAR(n) Maximum key length n =< 110
DATALN INT2(5) Length of the VARDATA record returned
VARDATA RAW(m) Maximum length of the data varies according to DBMS
Table Clusters
Similarly to pooled tables, cluster tables are logical tables which, when created, are assigned to a table cluster. Therefore, a table cluster, or just cluster, groups together several tables of type clusters.Several logical rows from different cluster tables are brought together in a single physical record. The records
from the cluster tables assigned to a cluster are thus stored in a single common table in the database.A cluster contains a transparent cluster key which must be located at the start of the key of all logical cluster tables to be included in the cluster. As well, a cluster contains a long field (VARDATA), which contains the
data of the cluster tables for this key. If the data does not fit into a field, continuation records are created.
Field Type Description
CLKEY1 CHAR(*) First key fields
CLKEY2 CHAR(*) Second key field
CLKEYN CHAR(*) nth key field
PAGENO INT2(5) Number of the next page
TIMESTMP CHAR(14) Time stamp
PAGELG INT2(5) Length of the VARDATA record returned
VARDATA RAW(*) Maximum length of the data section; varies according to database system
Working with Tables
The dictionary includes many functions for working with tables. There are five basic operations you can perform on tables: display, create, delete, modify, copy. Please do not confuse displaying a table with displaying the table entries (table contents). In order to display a table, it must previously exist; otherwise the system will display an error message in the status bar. For the following example, the table TABNA is used. To display this table, from the main dictionary screen, enter the table name in the Object name
input field with the radio button selected next to Tables. Then, click on the Display button at the bottom of the screen, or press the F7 function key, or, alternatively,
select Dictionary object Display from the menu.
In this screen, you can see table information such as
¨ Table type, shown next to the name of the object. In the example, it is a transparent table.
¨ Short text description.
¨ Name of the user who made the last change, and the date of the change.
¨ Master language.
¨ Table status. On the screen, you can see this table is saved and active.
¨ Development class. For information on development classes, refer to Chap. 6.
Delivery class, which sets the maintenance group for the table. It controls how tables will behave during client copy procedures, upgrades, and so forth.¨
Tab. Maint. Allowed flag, which indicates whether you can generate a screen for maintaining table entries.
¨Then, on the lower part of the screen, you can see the table fields with all associated characteristics such as:
¨ Field name.
¨ Key indicator. When set, this field is the primary key, or part of it.
¨ Data element.
¨ Basic data type.
¨ Length.
¨ Check table.
¨ Short text, describing the field.
Additional information about the table can be displayed by selecting the corresponding functions from the menu or directly from the application toolbar, such as keys, indexes, or technical settings
Standard table:
The key access to a standard table uses a sequential search. The time required for an access is linearly dependent on the number of entries in the internal table.
You should usually access a standard table with index operations.
Sorted table:
The table is always stored internally sorted by its key. Key access to a sorted table can therefore use a binary search. If the key is not unique, the entry with the lowest index is accessed. The time required for an access is logarithmically dependent on the number of entries in the internal table.
Index accesses to sorted tables are also allowed. You should usually access a sorted table using its key.
Hash table:
The table is internally managed with a hash procedure. All the entries must have a unique key. The time required for a key access is constant, that is it does not depend on the number of entries in the internal table.
You cannot access a hash table with an index. Accesses must use generic key operations (SORT, LOOP, etc.).
Index table:
The table can be a standard table or a sorted table.
Index access is allowed to such an index table. Index tables can be used to define the type of generic parameters of a FORM (subroutine) or a function module.

Hi,
As you mentioned there are 2 status can be maintained for documents like Equipment Master, Notification, Maintenance Order & other important business documents.
In case, client feels that system status is not enough to capture the details of the object, then user status can be used.
System statuses will be updated automatically based on business transactions which will be done on SAP.
For example, once the equipment is created, System status would CRTD (Created). If you install the same to some superior equipment or FL, then status would be INST (Installed).
If you keeping that equipment in Spare, then for that, you have to maintain separate User Status like AVLB (Available in Stock / Spare) so that through IH08, by using User status, you can the report which is available as spare.
These user status as per the name, should be updated by the user manually.

EXACT DIFFERENCE BETWEEN FULL LOAD AND REPAIRFULL LOAD?

HI Champ,
Can anyone explain me the exact difference between full load and Repairfull load?Give e some senario where we can go for this?Please.....
10zin

Hi,
Full repair can be said as a Full with selections. But the main use or advantage of Full repair load is that it wont affect delta loads in the system. If you load a full to a target with deltas running you again will have to initialize them for deltas to continue. But if you do full repair it wont affect deltas.
This is normally done we when we lose some data or there is data mismatch between source system and BW.
Check the OSS Note 739863 'Repairing data in BW' for all the details
Symptom
Some data is incorrect or missing in the PSA table or in the ODS object (Enterprise Data Warehouse layer).
There may be a number of reasons for this problem: Errors in the relevant application, errors in the user exit, errors in the DeltaQueue, handling errors in the customers posting procedure (for example, a change in the extract structure during production operation if the DeltaQueue was not yet empty; postings before the Delta Init was completed, and so on), extractor errors, unplanned system terminations in BW and in R/3, and so on.
Solution
Read this note in full BEFORE you start actions that may repair your data in BW. Contact SAP Support for help with troubleshooting before you start to repair data.
BW offers you the option of a full upload in the form of a repair request (as of BW 3.0B). If you want to use this function, we recommend that you use the ODS object layer.
Note that you should only use this procedure if you have a small number of incorrect or missing records. Otherwise, we always recommend a reinitialization (possibly after a previous selective deletion, followed by a restriction of the Delta-Init selection to exclude areas that were not changed in the meantime).
1. Repair request: Definition
If you flag a request as a repair request with full update as the update mode, it can be updated to all data targets, even if these already contain data from delta initialization runs for this DataSource/source system combination. This means that a repair request can be updated into all ODS objects at any time without a check being performed. The system supports loading by repair request into an ODS object without a check being performed for overlapping data or for the sequence of the requests. This action may therefore result in duplicate data and must thus be prepared very carefully.
The repair request (of the "Full Upload" type) can be loaded into the same ODS object in which the 'normal' delta requests run. You will find this request under the "Repair Request" option in the InfoPackage (Maintenance) menu.
2. Prerequisites for using the "Repair Request" function
2.1. Troubleshooting
Before you start the repair action, you should carry out a thorough analysis of the possible cause of the error to make sure that the error cannot recur when you execute the repair action. For example, if a key figure has already been updated incorrectly in the OLTP system, it will not change after a reload into BW. Use transaction RSA3 (Extractor Checker) in the source system for help with troubleshooting. Another possible source of the problem may be your user exit. To ensure that the user exit is correct, first load a user exit with a Probe-Full request into the PSA table and check whether the data is correct. If it is not correct: Search for the error in the exit user. If you do not find it, we recommend that you deactivate the user exit for testing purposes and request a new Full Upload. It If the data arrives correctly, it is highly probable that the error is indeed in the user exit.
We always recommend that you load the data into the PSA table in the first step and check the result there.
2.2. Analyze the effects on the downstream targets
Before you start the Repair request into the ODS object, make sure that the incorrect data records are selectively deleted from the ODS object. However, before you decide on selective deletion, you should read the Info Help for the "Selective Deletion" function, which you can access by pressing the extra button on the relevant dialog box. The activation queue and the ChangeLog remain unchanged during the selective deletion of the data from the ODS object, which means that the incorrect data is still in the change log afterwards. After the selective deletion, you therefore must not reconstruct the ODS object if it is reconstructed from the ChangeLog. (Reconstruction is usually from the PSA table but, if the data source is the ODS object itself, the ODS object is reconstructed from its ChangeLog). You MUST read the recommendations and warnings about this (press the "Info" button).
You MUST also take into account the fact that the delta for the downstream data targets is created from the changelog. If you perform selective deletion and then reload data into the deleted area, this may result in data inconsistencies in the downstream data targets.
If you only use MOVE and do not use ADD for updates in the ODS object, selective deletion may not be required in some cases (for example, if incorrect records only have to be changed, rather than deleted). In this case, the DataMart delta also remains intact.
2.3. Analysis of the selections
You must be very precise when you perform selective deletion: Some applications do not provide the option of selecting individual documents for the load process. Therefore, you must first ensure that you can load the same range of documents into BW as you would delete from the ODS object. This note provides some application-specific recommendations to help you "repair" the incorrect data records.
If you updated the data from the ODS object into the InfoCube, you can also delete it there using the "Selective deletion" function. However, if it is compressed at document level there and deletion is no longer possible, you must delete the InfoCube content and fill the data in the ODS object again after repair.
You can only perform this action after a thorough analysis of all effects of selective data deletion. We naturally recommend that you test this first in the test system.
The procedure generally applies for all SAP applications/extractors. The application determines the selections. For example, if you cannot use the document number for selection but you can select documents for an entire period, then you are forced to delete and then update documents for the entire period in the data target. Therefore, it is important to look first at the selections in the InfoPackage exactly before you delete data from the data target.
Some applications have additional special features:
Logistics cockpit: As preparation for the repair request, delete the SetUp table (if you have not already done so) and fill it selectively with concrete document numbers (or other possible groups of documents determined by the selection). Execute the Repair request.
Caution: You can currently use the transactions that fill SetUp tables with reconstruction data to select individual documents or entire ranges of documents (at present, it is not possible to select several individual documents if they are not numbered in sequence).
FI: The Repair request for the Full Upload is not required here. The following efficient alternatives are provided: In the FI area, you can select documents that must be reloaded into BW again, make a small change to them (for example, insert a period into the assignment text) and save them -> as a result, the document is placed in the delta queue again and the previously loaded document under the same number in the BW ODS object is overwritten. FI also has an option for sending the documents selectively from the OLTP system to the BW system using correction programs (see note 616331).
3. Repair request execution
How do you proceed if you want to load a repair request into the data target? Go to the maintenance screen of the InfoPackage (Scheduler), set the type of data upload to "Full", and select the "Scheduler" option in the menu -> Full Request Repair -> Flag request as repair request -> Confirm. Update the data into the PSA and then check that it is correct. If the data is correct, continue to update into the data targets."

What are the exact differences betweern mac book air and mac book pro

I have not used mac book b4, and now I consider to buy a mac book. I am a college student and majoring in computer science. Can someone tell me what are the exact differences between MBP and MBA? I know the CPU in MBP is better than MBA and what else? Which one would you recommend me to buy? Waiting for your response. Thank you so much!

This forum is
Apple Support Communities > Notebooks > MacBook Pro > Discussions
So the question is relevant at least to the extent that it is asking for a comparison between a MacBook Pro and a MacBook Air
MacBookAir definitely favors portability and sports a dual core i5 at 1.5GHz (max RAM is 4GB not user upgradable)
MacBook Pro has upto a quad core i7 at 2.4GHz (ships with 4GB and upgradeable to as much as 16GB on some models)

Exact difference between se09 and se10

Hi all,
i want to know the exact difference between se09 and se10 .
i know
SE09 is the workbench transport requests transaction - here the developers can track changes to all ABAP workbench objects (dictionary, reports, module pools, etc). This is a developer-specific transaction and mostly all developers have access to this transaction.
SE10 is the customizing request display transaction - this displays all the customizing requests in the system. Again, this could be restricted to Business analysts if required, since they would be doing most of the customizing changes in the system.
but i think this is not the correct answer which is already appear in the thread list
recently sombady has answer like the one which i have mentioned above but the interviwer said that this is wrong.
CAN ANYONE TELL ME THE EXACT ANSWER AND HELP ME OUT.
Regards
fareed

Hi Fareed,
First of all, i would say its a nice obsevation. As soon as i saw your post i started checking both transactions in seperate window and i found something interesting.
My Observation is as follows:-
When we create a Transaction, apart from the Transaction Name, Program Name, Screen Number etc., we also can give someting called "AUTHORIZATION FOR CALLED TRANSACTIONS", under the menu: UTILITIES of the window.
Also we can use TRANSACTION:SE97, Maintain Transaction call Authorization in CALL TRANSACTION. Here we maintain the list of TRANSACTION CALLED for our Calling Transaction.
Now if you see, this list for Transaction SE09 and SE10, The Authorization for Called Transaction Differs a lot. Hence the difference bettween SE09 and SE10 is mainly the AUTHORIZATION Objects.
NOTE: This is my own observation, so there are chances of misinterpretation from my side, accounting to the human err. But this is something new to me too.
Thanks and regards,
RAVI :).
