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.
The batch class is assigned to the class type 022 or 023, depending on the batch definition level (plant, client, or material level).
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.
The following prerequisites must be fulfilled before a conversion can take place:
· The material must be subject to batch management.
There must not yet be any batches for the material.
· 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 ® Maintain Object 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.
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.
You can include any number of materials in a conversion. There is no timeout when performing conversions online.
Conversions are divided according to the following statuses in the status overview:
· Being created
· Released
· Current
· Finished with errors
· Finished without errors
· Deleted
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.
The conversion is documented in change documents for the material classification. To view the change documents, go to the material master record (Logistics ® Materials Management ® Material Master ® Material ® Display ® Display Current) and switch to the classification view by choosing Environment ® Change documents.
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:
· Add or create
· 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
· Execute
· Release
· Process mass data
This authorization enables you to perform conversions using background processing.
