Suggestion:
I think you are getting the batch field mandatory when you do the confirmation and do the valuation. For this to remove, in the routing header, maintain partial lot assign as partial lot for each inspection point. Currently it will be either partial lot assignment according to plant level setting which inturn will be partial lot for each batch and inspection point (plant level setting).
If you want to reflect partial lot for each inspection point to all routing, kindly change the same in the plant level setting:
QCC0 -> Basic setting -> Maintains Settings at plant level -> Result recording -> Partial lot assign -> You can use the entry in this list field to set the detailing levels for the assignment of manufactured quantities.
In the first and most detailed level ("Partial lots not defined"), the manufactured partial quantities are assigned to inspection points for which inspection results are also recorded.
In the second detailing level ("Partial lot for each inspection point"), the partial quantities, to which the inspection points are assigned, are combined into partial lots.
In the third detailing level ("Partial lot and batch for each inspection point") , partial lots are combined into batches.
If you define partial lot assignment in the task list header, this specification overrides the default values at plant level.
If no entry exists in the default values at plant level, this means that partial lots are not defined.
This should solve your issue.
