Assign text to E-Commerce B2B

We are using CRM 5.0 and E-Commerce B2B.

In text object CRM_ORDERI I assign new text ID's (ZD04) and text procedure (Z4) for sales item. I assign access sequence ISA_AG01 to the text ID.

However text I added to documents in the E-Commerce web channel and press update (or save) the texts disappear from the document, and of course are not in the document CRM GUI.
