LOT Status Group - How to avoid Primary location being considered in lot status group process

Hi,

Need to commit/release inventory from particular location (say FG) for certain order type.

Created a Lot status group and updated all lots of FG location with the lot status group code.

While running pick slip, inventory is getting committed to FG location(what is available) and remaining is getting committed to primary location where it should not.

For example:

Lot status code: A.   This status code is updated in all Lots of FG location.

Lot status group: FGLC

All lots of Primary location is having lot status code as BLANK.

Ordered quantity: 100 qtys

FG Location available quantity: 80 qtys
