applies-to and applies-from confusion

in output and consumption journal…we see ‘applies-to entry’ and ‘applies-from entry’…i am confused about which to use when.

mostly we need this for reversing output or consumption…

can someone explain the concept of these fields.

You can type F1 when clicked onto these fields to read the Help about them.

Applies-to Entry Field

The Item Journal Line Table

This field is used if the quantity in the item journal line should be applied to an already-posted document. If this is the case, enter the entry number of the item ledger entry to which the item journal line should be applied.

Applies-from Entry Field

The Item Journal Line Table

This field contains the number of the item ledger entry from which the quantity on the item journal line should be applied. Entering a value in this field creates a link in the Item Application Entry table between the two entries, ensuring that the cost from the inbound item ledger entry is forwarded to the outbound item ledger entry.

I know they are not really descriptive, but perhaps they will give you a start.
