Whenever I am attaching components in task list, item
category is coming "L" i,e stockable by default & it is greyed out. I want to
change it to non stockable.
In standard SAP in a task list the item cat is taken
from the Material Master . That is the reason its greyed . To solve your issue
you can create the BOM and have the non stock spare added as a BOM. In the task
list you can select material from BOM.
