Batch Class Conversion
Use
This function allows you to change the assignment of a material subject to batch management and its batches to a batch class. The existing characteristic value assignments remain the same.
Note
The batch class is assigned to the class type 022 or 023, depending on the batch definition level (plant, client, or material level).
Integration
After a conversion has been released, you cannot change the old and the new class until the conversion has been successfully completed.
A material can only be assigned to one conversion at a time.
For batch classes, it is not possible to change the class assignment using engineering change management for the classification system.
Prerequisites
The following prerequisites must be fulfilled before a conversion can take place:
The material must be subject to batch management.
There must not necessarily be any batches for the material, however.
A batch class must be assigned to the material or at least one batch.
After the conversion, a material with no class assignment receives the new class.
All batches that previously contained the old class receive the new class.
After the conversion, unclassified batches remain unclassified.
The status of the new class must allow this classification.
You make the settings for the class status in Customizing for
Classification
by choosing
Classes
MaintainObject Types and Class Types
.
The new class must contain all the characteristics of the old class.
The new class can also contain additional characteristics.
Conversions do not alter the classification status.
When a conversion is released, none of the classes should be being processed.
Features
Conversions Online and in the Background
Call the transaction by choosing
Logistics
Central Functions
Batch Management
Tools
Batch Class Conversions. You can then:
Create conversions
Change conversions
Display conversions
Check conversions
Release conversions
Start conversions
Delete conversions
In this transaction you process and analyze conversions.
You can perform conversions online using the transaction, or in the background using the report RVBCR_CLASS_REPLACE.
Note
You can include any number of materials in a conversion. There is no timeout when performing conversions online.
Conversion Status
Conversions are divided according to the following statuses in the status overview:
Being created
Released
Current
Finished with errors
Finished without errors
Deleted
Estimation of the Time Required for a Conversion
When the system checks a conversion, it also creates an estimate of the resources required for the conversion. The estimated value is shown in the status overview. This value should give you a rough idea of how long the conversion will take.
Documenting the Conversion
The conversion is documented in change documents for the material classification. To view the change documents, go to the material master record (
Logistics

) and switch to the classification view by choosing
Environment
Change documents
.
Authorization for Conversions
Using the authorization object M_MATE_ CHC , you can control which activities the user can perform for conversions.
The following activities are assigned to this authorization object:

Change
You need this authorization to be able to flag a conversion for deletion. To actually delete a conversion from the database, you need authorization to delete conversions.
Display
Delete
