How To Fix DT195 - Multiple fields of type LANG; select one of these as the text language

SAP Error Message - Details

• Message type: E = Error

• Message class: DT - Table activation (incl. indexes)

• Message number: 195

• Message text: Multiple fields of type LANG; select one of these as the text language

What causes this issue?

If the RFC data is transported between MDMP systems (non-Unicode systems
with several code pages) and Unicode systems, it must take the coding of
the text data into consideration. To do this, it uses the language
information that is stored in the fields of the LANG type. If a
structure contains several fields of the LANG type, the LANG field in
which the language is entered for coding the text data must be
selected.
Without this selection, the RFC will use - for conversion of the text
data - a transport code page that depends on the logon language. This,
in turn, will mean that text data will be converted incorrectly and can
even become corrupt.
Example:
Table T002T has 2 LANG fields: SPRAS and SPRSL., where SPRSL is the
language whose name - translated in language SPRAS - is stored in the
SPTXT field. Here you also have the SPRAS field marked as the text
language.
INCLUDEs:
Newly created structures that have further structures included in them
(.INCLUDE) do not inherit the text language selection of the included
structures. The text langauge must be selected at the level of the newly
created structure.
For Prioritization:
If the questioned strcuture is used in the interface of an RFC-enabled
function module, this check has higher priority. Less higher priority is
given to cases where the structure is currently not used in the RFC. The
information on the text language, however, is used for text conversion
within the IMPORT FROM DATABASE and at other external interfaces in the
system so that such cases should be processed as well.

How to fix this error?

Select the table or structure in question.
Display the field list and expand possibly existing, included
structures.
Click the field of the LANG type that specifies the text language. The
field maintenance box contains a checkbox that you can use to mark this
field. This checkbox contains an F1 help.

• What is the cause and solution for SAP error message DT195 - Multiple fields of type LANG; select one of these as the text language ?

  The SAP error message DT195 indicates that there are multiple fields of type LANG (language fields) in a data structure or table, and the system requires you to specify which one should be used as the text language. This error typically arises in the context of data dictionary objects, such as structures, tables, or views, where multiple language fields are defined.
  Cause:
  
  Multiple Language Fields: The data structure or table has more than one field defined as a language field (type LANG). SAP needs to know which one to use for text language purposes.
  Ambiguity: The presence of multiple language fields creates ambiguity for the system, as it cannot determine which field should be used for language-specific operations.
  
  Solution:
  To resolve the DT195 error, you can take the following steps:
  
  Identify Language Fields: Check the data structure or table definition to identify all fields of type LANG.
  Select a Primary Language Field: Decide which of the language fields should be used as the primary text language field. This decision may depend on business requirements or data usage.
  Modify the Structure:
  
  If you are working with a custom structure or table, you may need to modify it to ensure that only one field of type LANG is present.
  If you need to keep multiple language fields, consider renaming them or changing their types if they serve different purposes.
  
  
  Adjust Data Dictionary Objects: If the error occurs in a view or a similar object, ensure that the view is correctly referencing the intended language field.
  Re-activate the Object: After making the necessary changes, re-activate the data dictionary object to apply the modifications.
  
  Related Information:
  
  Data Dictionary (SE11): You can use transaction SE11 to view and modify the data dictionary objects.
  Field Type LANG: In SAP, fields of type LANG are used to store language codes (e.g., EN for English, DE for German). Ensure that the field you choose is appropriate for the context of your application.
  Documentation: Refer to SAP documentation or help resources for more information on data dictionary design and best practices regarding language fields.
  
  By following these steps, you should be able to resolve the DT195 error and ensure that your data structure or table is correctly configured for language handling.
