Characteristics in Planning object structure
When we create any Master Planning object structure ( MPOS)we see characteristics at right side of MPOS from where we have to select the required characteristics to left side and then these characteristics would be a part of our MPOS.
My question is from where these characteristics comes from. I looked at RSA1 and it seems they comes from there but some of them comes from unassigned nodes and some from Info providers.
Could any one tell me the logic of the characterists that appears while creating MPOS.
Thanks in advance.
