Answer 1

Assign plants c, d, e to same company code.
If you want to create a Stock Transfer Order,
maintain A as supplying plant. (create vendor master linked to purchase org and company code)
maintain c, d, e as receiving plants. (create customer masters linked to company code)
Ignore Plant B (if no changes to stock is happening there).
Do a 2 step stock transfer, when stock is in transit, after 1st step, you can assume stock is moving thru Plant B.
Settings For Stock Transport Order Without Delivery:
Order type UB
Item category U
GI: 351
GR: 101
Delivery type: Blank
Settings For Stock Transport Order with Delivery:
Order type UB
Item category U
GI: 641
GR: 101
Delivery Type: NL
If STO not needed, use 303 GI from Plant A and 305 GR in Plant C, D, or E thru MIGO.
If Plant B should be considered in stock transfer,
Just do a one or two step transfer from A to B, then from B to C, D or E.
