Error code –10315
Error constant CANNOT_SKIP_GEN_NLDT_WITHOUT_MOD_NLDT
Probable cause

The MobiLink server will rely on the user-defined prepare_for_download and modify_next_last_download_timestamp scripts to generate the next last download timestamp that will be used to create the download stream in the next synchronization.
