Reason and Prerequisites

This problem is caused by a program error.
The problem is due to missing functions.
You must retrieve the null cells in the method Execute in the class cl_salv_wd_service_manager. After you execute the services, you must check whether the data sequence has now changed. If it has changed, you must reset the null cells.

In urgent cases, you can implement the correction instructions as an advance correction.
Before you do this, see Note 875986 for information about transaction SNOTE.
Before you implement the advance correction (if it is available and you want to implement it), see Note 875986. It contains current corrections that refer to the SAP Note Assistant and prevent problems during an import. After you implement the composite SAP Note, you must call transaction SNOTE again.
