Plan access security -Assignment Set

Hello all,

We are planning to run one ASCP plan for each Operating Unit (with multiple orgs within each) for security reasons (so that planner for that OU has access to only their OU). We'll not have IR-ISO across OUs.

So,questions around that are:

1) Would this require creating multiple Sourcing Rule Assignment Sets (one for each OU) ? Even if we did,I see that Organization access doesnt seem to work for this form. This form seems to be always at the Global level

2) Are there issues in using multiple assignment sets ? (one for each plan)

Thanks

Steve
