In CJ20N, on create material component, copy longtext from other material component

[fabian_nelis]

Hello, in the project builder (CJ20N), I'm trying to copy the Longtext from an existing componenent, to a newly created one (on creation)

I have played with some FM, but after creation of the component, when visiting the longtext, it stays empty:

- CO_ZK_TEXTKEY_RESB to get the textkey

- READ_TEXT

- COPY_TEXT

- INIT_TEXT

- SAVE_TEXT

- TEXT_COPY

Any solutions to my problem?

Thanks in advance
