we are not able to pull activity created by employee from CRM ser to Mobile

Hi,

We are not able to get the activity details created by an employee from CRM to Mobile. We have assigned proper Subcription with filter value. but still this data inis not coming to Mobile client. When i try to change the activity in CRM server it says "Document is being distributed - changes are not possible".We do not know why we are not able to change this. Please help.
