Diagnosis
You want to save the confirmation/picking from the goods movementoverview.
In this case the system checks whether a parallel entry quantity hasbeen defined for all catch weight materials.

System Response
As long as no parallel entry quantity for items of a catch weight
material has been specified as 'zero', the system provides details forthe quantity.

Procedure
You can post catch weight materials without an entry quantity but theseare posted without a value when the parallel unit of measure beingused is the valuation unit of measure.
You have two options:
If you want to enter a parallel entry quantity in retrospect youcan do so in the overview.
If you want posting to be performed without values you should setthe logistical entry quantity to zero.
You can then save the confirmation/picking.
