Batch Material Stored As Small Letter

How batch with lower case was stored into system?

Goods receipts are posted via IDoc (third-part external system) / Bapi (custom internal program).
 
During the IDoc processing, new batches are created.  In the respective interface, the batches are transferred in lower case letters.

The system does not check this and the batches are created in the database with lower case letters. These batches cannot be processed online.  For e.g. MIGO

For example:

I discovered that our third party warehouse partner send in a wrong idoc where the batch number was in lower case.

It will be impossible to used MIGO to do any movement as the system will AUTO CONVERT all characters to LARGE CAP.

Batch Number in Small Caps
 

No system checks: 

The IDoc / Bapi expects the data to be posted in technical notation.  Conversions or checks, as carried out during online processing, do not take place.

This problem was classified as a consultancy issue as behavior corresponds to the standard SAP design of the IDOC/Bapi.
 

Solution:

You can clear the stocks with a corresponding IDoc (third-part external system) / BAPI call (custom internal program), which you need to create, by transferring the batch using lower case letters again.

The batch can be reorganized when it has no more stock.
