Select entries function seems to disabled in item tracking line window

Hi all,

my client is using item tracking functionality for sales inbound and outbound transactions and was working perfectly.Recently they made a sales return order and the items they entered manually in the sales return order lines because the items comes from different posted invoices. When they trying to assign the corresponding item sales entries by using the Function-------->Select Entries from the Item tracking window, the functionality seems to be disabled…earlier they were doing the same way…has anyone got any idea about this?

Thanks in advance :slight_smile:

Check ITEM:

Costing Method : Specific .

Reordering Policy : Lot for Lot.

but earlier they have done the same process for those items successfully and the item setup remains same now.
