Hi Maria,
I will try to guide you on how to proceed-
1) Get a Network in CJ20N with materials attached to different activities.
2) Click on the network header in CJ20N.
3) On the right hand side there is "overview" written . Click on component overview and you will see all the materials list attached to DIFFERENT activities as mentioned below and there Storage location is not editable.
4) Now i will show you where the SLOC is EDITABLE.
a) Click on any activity on which the material is assigned.
b) Now click on component overview.
c) You will see a list of all the materials which are assigned to THAT PARTICULAR activity only.
d) And there i can change the SLoc of the material
So difference here is, at Header level component overview the Sloc is non-editable and its editable at Activity level component overview.
And i want to make it editable at Header level.
Hope you get the issue now.
Regards,
Manan
