Hi, can i hide the column SYNC_KEY? How?
well, it is as easy as this: do not show it
But the long version: even if you just tick one single column in MEREP_SBUILDER, it will always download the SYNC_KEY. Well, as the name tells you, the SYNC_KEY specifies this item for the SMARTSYNC framework. So without that key, smartsync can not work.
BUT: on the device you are responsible what information you display on the screen. So if you have a fully customised screen, I guess in your JSP code you have a loop counting from 0 to x to show col(i). Normally the SYNC_KEY ist the first column, so just count from 1 to x.
Or you will find something like <%=object.getKey()%> in your code. If this is the point, then just delete that tag or even better, the complete column. Just be aware of the HTML table structure.
Hope this helps to solve the issue.
