In this field you can specify a filter on the type of item ledger entry. This means that the program will apply the item ledger entries that you have specified in this field in the Analysis Columns with this analysis type.
You can, for example, enter the filter ‘<>Transfers’ to specify that Item Transfers should not be included in the calculation in this line. If you enter the filter ‘=Sales’, only Item Ledger Entries that are derived from a sale will be included in your analysis report.
