I like Nashant Rana’s weblog because he often puts in very small but very useful posts, which get straight to the point, like this one.
Hiding Create Related tab from a custom entity in crm 2011
The example just shows how to hide a custom entities create related tab
Suppose the name of the custom entity is new_case.
We can make use of following XML definiton to do that
<CustomActions>
<HideCustomAction Location=”Mscrm.Form.new_case.Related”
HideActionId=”Sample.Form.new_case.Related.HideAction” />
<HideCustomAction Location=”Mscrm.HomepageGrid.new_case.Related”
HideActionId=”Sample.HomepageGrid.new_case.Related.HideAction” /><CustomActions>
