Original Language in BSP Application HCM_LEARNING

Hi BSP Experts

We are using HCM_LEARNING. Unfortunately the original language was set to "DE" by SAP Development Team.

I need to change the original language to "EN" in the BSP Application and then change all OTR texts

according to SAP Note 574110 (Program SOTR_PROGRAM_02).

My questions:

- How do I change the original language in BSP Application (language field is not modifiable)

- SOTR_PROGRAM_02 lists all OTR Texts, but does not change anything. Message is:

"Changes only possible in original system"

Please advise me on how to do this correctly.

Thank you very much and kind regards

Paul
