New DME format tree not appearing outside t.code DMEE

Hi all,

I'm following the instructions from S-Note 2184508, which contains an XML (CH_XML_CT) for upload in DMEE transaction.

The upload works and the new format tree can be saved without errors. Consistency check says everything is valid.

I then proceed to activate the new format tree, which also works fine without errors or warnings.

I then want to proceed with transaction OBPM1 to do a new entry. But my new format CH_XML_CT does not appear in F4 search for the field "Format".

Do you have any suggestions what needs to be checked or did I miss a step?
