Hi,
the text id is related with the document type. In your EWM document type there is a text profile. This is the profile you mention (whereas you do NOT create a system profile, you always create a customer profiel) This text profile contains text IDs. And these IDs must match the IDs you use in ERP if you want to copy the text from ERP deliveries to the EWM delivery.
