" The role of the update work process is very important since it is responsible for recording the changes in the database. The process performs its functions when the ABAP applications are programmed with the statements in the UPDATE TASK. This type of updating is asynchronously performed, ie. The programs leave update records in a queue to be processed and then continue to the update process. Normally, it runs without any intervention from the SAP R/3 management, still R/3 includes utilities to monitor check and perform management operations on the updation processes. In case any updating error takes place, the system places a message to the user regarding the error and an alert is triggered in the CCMS monitor. For the update functions go to Administration menu bar option --> Monitor option ---> Update option. An initial update screen showing various functions appears. The initial update screen is used to display the system update records with error status or the records which have not yet been processed, activate and deactivate the updating in the whole SAP system. It is also useful to display the update statistics, to display the data on the erroneous update records and reprocess them, either in real or in test mode and to send waiting update records for processing after a deactivation/activations of the updating and delete update records. Many work processes of the type R/3 system update the database. A database interface is included by the dialog and background work processes, which can directly update the database. However, the update work processes ca also be used for updating the physical database in asynchronous way. If it is asynchronous updating, according to which the transactions are programmed in the ABAP business applications, then in the database commit phase, the transactions pass the update records to the update work processes."
"The SAP Control Framework is used for the communication between the controls on the presentation server and the ABAP application server. In ABAP Objects, it is programmed, and contains a set of global classes that you can find in the Class Browser under Basis -> Frontend Services. Between the application server and presentation server these classes encapsulate the communication, which is implemented using Remote Function Calls. There is a global class, which encapsulates all application controls. In the class Browser under Basis -> Frontend Services or Basis -> Components Integration, you can find the SAP Basis Controls."
If you wish to display Material data related to Material General Data, Material Plant Data and Material Valuation Data then you can use the following BAPI. This BAPI displays the above mentioned data for a Material.
BAPI/Function Module to display Material Data / Display Material Data BAPI/Function Module
BAPI_MATERIAL_GET_DETAIL
This BAPI has 4 input parameters
Material (Mandatory) Plant Valuation Area Valuation Type
Please find the code below.
REPORT ZEX_GETMATDET .
Parameters: p_matnr like BAPIMATDET-MATERIAL, p_werks like BAPIMATALL-PLANT, p_valara like BAPIMATALL-VAL_AREA, p_valtyp like BAPIMATALL-VAL_TYPE.
Data: st_matgendata like BAPIMATDOA, st_matplantdat like BAPIMATDOC, st_matvaldat like BAPIMATDOBEW, d_return like BAPIRETURN.
Always specify your conditions in the Where-clause instead of checking
them yourself with check statements. The database system can then use an index
(if possible) and the network load is considerably less.
Always use Pretty Printer and Extended Program Check before releasing the code.
Do not leave unused code in the program. Comment the code thoroughly. Align the comments and the Code. Follow the SAP Standards and SAP Best Practices guidelines. It’s a good practice to take a dump of the code on your local drive.
