Starting Mass Processing
Mass processing can be started in the following ways:
Triggering the execution of a function
The execution of a function can be triggered as follows:
Execute function immediately
The functions are executed directly after mass processing has been triggered. This can take a long time for functions that require a lot of system resources. However, you can immediately check whether the function was successfully executed.
Execute function with dialog transaction
Further processing is controlled by a dialog that is specific to the function. This option is available for the following functions: Confirmation, Picking, Log display.
Create a function request (refer to Processing Requests)
First, requests are created without any further checks. The requests are created very quickly. Mass processing is actually executed with the program COWORKDISPATCH. As a result, it is delayed until the next time the program starts. You can decouple the function in terms of time, so that the main work takes place at night, for example. The end users create requests and system administration takes care of their execution.
Execute function in the background
First, requests are created without any further checks. Then a background process is started, which processes these requests immediately. Scheduling a background job does not create any administrative work and reduces the workload for the dialog.
Parallel Processing
For parallel processing, you define server groups for mass processing (COWORK-DIALOG, COWORK-BATCH). This enables you to speed up the execution of processing.
Mass processing online/ in the background.
You can either execute mass processing online or you can schedule it in a background job (no online steps are possible).
Application Toolbar with Mass Processing Functions
You can define that an application toolbar, with selected mass processing functions, is displayed in the list of the selected objects. You can use this application toolbar to execute the functions in the dialog.
For more information refer to Display Application Toolbar with Mass Processing Functions.
Test Run
You can decide whether changes caused by a mass processing function are executed in the form of a test run only. Error messages that may occur are collected. No changes are updated to the database.
You can use the test run for these functions:
Close
Set/delete user status
Release
Costing
Generate capacity requirements
Technically complete
Scheduling
WM material staging
To test a function, select the option Test function without changes to data on the Mass processing tab page.
Log
Log records are written and saved as a function is being executed. They provide information about the execution of a mass processing function. If no log record exists, the function was executed without any problems. The log records are assigned to the order or the collective order
