A blank posting level is used in the data collection task. This task collects data from different sources, such as the general ledger, subledgers, and other systems, before the consolidation process begins.

In SAP Group Reporting Data Collection forms, the possible period mode is Periodic, which represents monthly, quarterly, or yearly periods.

FS items can be determined for balance carry forward using a configuration table, their FS item type, and their role attribute. These factors help to classify FS items for different purposes in the consolidation process (SAP Help Portal: Define Financial Statement Items).
