Adds a date range filter to the Sales and Purchase ledger allocation screens



If there are a lot of allocations to be made, it can be useful to have a date range filter on the transaction lists - particularly if automatic allocation is to be used.

This enhancement adds a new option to the right-click menu:

When "Date range" is selected, a from date and/or to date may be entered:

The list of transactions is then filtered by these dates.  The filter may be removed by selecting Cancel.

Separate date ranges may be used for Credits and Debits.
