How To Fix TW385 - Language group &1 only contains lowercase letters

SAP Error Message - Details

• Message type: E = Error

• Message class: TW - R3trans - Messages

• Message number: 385

• Message text: Language group &1 only contains lowercase letters

What causes this issue?

The language group specified in TPPARAM only contains lower case
letters. As from Release 4.0 lower case letters are required to
identify languages internally, R3trans is incompatible in as much that
lower case letters in the language group are no longer automatically
converted into upper case letters.

System Response

The language group is extended with upper case letters.

How to fix this error?

Check the transport profile TPPARAM and enter the language group in
upper case letters if you wish to work in the language corresponding to
the upper case letters.
