Change Secondary language to English

Question

Hi ,
I have English(EN) as the system language and German(DE) as the secondary Language in my development environment.
Also Norwegian(NO) language is installed for which supplementation language is English.
While logging in with NO and executing certain tcodes for example MM02 , I am getting a mixture of all three languages and no translation.
Screenshot attached.
I would like to know if someone has encountered this scenario before and would be able to help with a solution.
Also most importantly, if I want to set the secondary language as english now, could I do the parameter change at any time and take a system restart or should it be done only while installing a new system  when there are no languages other than the ones delivered by SAP i.e. DE and EN.
Thanks for your inputs.

Answer 1

Hello
Supplementation and secondary language should be the same as stated in the here under note.
You should then change secondary language parameter to English (zcsa/second_languages = E), you will then get rid of the german texts.
Changing the secondary language parameter could be done at anytime, it just requires to restart the SAP instance.
To my knowledge running supplementation could only help if
1) language installation/supplementation was done wrong (language imported after applying SP, or creating working clients from 000 or supplementation not done in client 000)
2) you did import support packages and did not run supplementation again

3.Supplement the language with English or German. Keep in mind that supplementation must be done in all your clients, starting with client 000.
To do this,call the following menu option:Language->Supplement Language.Keep the default selection and execute it.
4.Once that you have supplemented the affected language, set the parameter zcsa/second_language to the supplemetary language, that is:
A) If you have supplemented the language with English set the parameter
   zcsa/second_language to English  ( zcsa/second_language = E )
B) If you have supplemented the language with German set the parameter
   zcsa/second_language to German  ( zcsa/second_language = D )

1.3. Secondary language
A disadvantage of the supplementation is that changes to texts in the supplementation language are not copied again to the language that is to be supplemented, because there is no longer any translation gap there since the first supplementation.  Therefore, the secondary language was introduced.
The secondary language mechanism ensures that the system displays missing screen texts, ABAP Dictionary texts and menu texts in the secondary language.  Therefore, these texts (tables D021T, DD04T and RSMPTEXTS) can be left out and are left out in a supplementation if the secondary language is the same as the supplementation language.  In this way, changes in the supplementation language also automatically take effect for the language to be supplemented.
Therefore, we recommend that the secondary language should be the same as the supplementation language.
