Standard BEx transporting Request

Question

Hi Dudes,
Can u explain me with a scenario, what is this Standard BEx Transporting Request and what is the purpose of this,
Thankyou.

Answer 1

Hi,
This is what note says:
Symptom
Editing of a query in Query Designer may return the various error messages concerning transport system. Query or query component can not be changed or saved.
The following error messages are possible:
'Query could not be saved due to a problem in transport' message R9 124;
'BEx Transport Request XXX... is not available or not suitable. Choose an existing request';
'Object ELEM XXX... could not be saved to order YYY...';
'A dependent object is being locked by the transport system' message R9 113
'The dependent objects are in different transport orders' message R9 114;
'The upgrade is already running - you are not able to change objects'.
In some particular cases using NW 2004s server with 3.x Query Designer
'Operation failed, no message available from server'.
Other terms
Query, Query Designer, Correction and Transport System, CTS, ELEM, Transport Request, Changeability.
Reason and Prerequisites
The error messages rise as the result of wrong administration of Correction and Transport System (CTS).
Transport System Mode
Two main modes of Transport System can be used for BW system: Standard Transport System and BW Transport System. Both modes require different administration efforts.
Standard Transport System (system default)
Within this mode an assignment of newly created query elements is done during save procedure. System asks for appropriated Package and corresponding Transport Request within this Package. The mode allows separating of changes done in the system different users in different Transport Requests. Users must be authorized to create new Transport Requests or to write into existing Transport Requests.
BW Transport System (recommended for handling of BEx objects)
Within BW Transport System initial assignment of newly create query elements is done automatically to $TMP Package. This is a Package for temporary objects and does not require modifiable Transport Request. Changes of those query elements can be done without further restrictions. Further assignment to a Package and corresponding Transport Request can be performed using Transport Connection of Administrator Workbench (transaction RSA1).
All kinds of changes for query elements which already have been assigned to any Package different from $TMP (for example, queries transported from another system) must be registered in so-called Standard BEx Request. Using Standard BEx Request all changes done to query elements can be also transported to any other system. If the old Standard BEx Request has been released, another one must be created immediately in order to allow further changes for query elements.
The typical reason for error messages listed above is a situation when NO Standard BEx Request is available anymore in the system. The algorithm of query SAVE contains a transport systems check. If the transport system check fails, no changes are possible.
Changeability of query elements
The recommended setting for query element (ELEM) is 'Everything Changeable'. Using of other settings, like 'Original Changeable' or 'Nothing is Changeable', will make editing of objects not possible when the general system changeability will set to 'not changeable' (SCC4).
Setting 'Original Changeable' allows changes only for query elements which have been created in this particular system. Quite often an ordinary query may contain, for example, variables or other reusable components created in the other systems. In this case changing of a query containing those objects will be not possible.
Changeability of Package
Package (Development Class) where the corresponding Transport Request has to be created must be changeable. If a Package has a property 'Package is not extendable' set to true, no requests can be created within this Package. This means no objects can be registered.
Solution
The following messages mainly happen if BW Transport System is activated. The existence of Standard BEx Request and correct settings for object changeability should be checked.
'Query could not be saved due to a problem in transport';
'BEx Transport Request XXX... is not available or not suitable. Choose an existing request';
'Operation failed, no message available from server'.
How to create a new Standard BEx Request?
Start Administrator Workbench (RSA1) --> Transport Connection. Find button BEx. Under the button user is able to create/assign a new Standard BEx Request.
How to check Changeability of object?
Start Administrator Workbench (RSA1) --> Transport Connection. Find button 'Object Changeability'. Set property 'Everything changeable' for query elements (ELEM).
How to check Changeability of Package?
Start transaction SE80 --> select corresponding Package --> find properties dialog. Check whether the property 'Package is not extendable' is set to false. Assignment of query elements (R3TR ELEM) to a corresponding Package is stored in the table TADIR (field DEVCLASS). In order to obtain a list of query elements used in a definition of a particular query having problems use the function RSZ_X_COMPONENT_GET with the I_OBJVERS = 'A', I_COMPID = technical name of a query. Execute the function and copy all elements (ELTUID) from the exporting table C_T_ELTDIR. Use this selection as the input parameter for selection from TADIR table (field OBJ_NAME). Collect all Packages and check the changeability as described above.
The following messages mainly happen if Standard Transport System is activated. The problem happens in case, when one or several objects from definition of a particular query have been already written in another modifiable Transport Request. In BW 3.x each object can be processed only within one Transport Request.
'Object ELEM XXX... could not be saved to order YYY...';
'A dependent object is being locked by the transport system';
'The dependent objects are in different transport orders';
The situation may happen, for example, if a Query A contains a variable which has been already used in another Query B assigned to different Transport Request. In this case, saving of Query A will be not possible while the Transport Request containing the shared variable is not released.
How to find an assignment of object to a Transport Request?
Start transaction SE03 and select 'Search for objects in requests/tasks'. Provide ELTUID of the element which can not be saved. Object type is R3TR ELEM. Search for modifiable Transport Requests containing this element. If corresponding Request is found, it can be released. After that is will become possible to save this query element into another Request.
Changing of query elements during running upgrage is not possible. The system sets a global lock in order to prevent any change which may potentially affect the consistency of objects. In such situation users should stop the upgrade procedures and wait until the process will finish.
