Answer:
Movement type 543 is used in Subcontracting Process.
A short example:
You have 10 units of a raw material (ROH) and you send it to a Vendor (SAP uses Movement Type 541 to perform this operation). Vendor will product Material B with material you have sent.
Now you do not have any units into your stock, but, you have 10 units into Special Stock (vendor).
Status at this point:
Material A = 10 (Special Stock – Vendor)
Material B = 0
Ok, then your vendor uses 10 units to product 1 Finished Product (FERT), and vendor will send you this Finished Product (Material B).
Now you have to perform 101 Movement Type for material B (Finished Product).
Status at this point:
Material A = 10 (Special Stock – Vendor)
Material B = 1
Ok, now you must perform 543 Movement Type for material A (Raw material) you have sent. That means this material was consumed in order to product Material B.
Status at this point:
Material A = 0 (Special Stock – Vendor) due 543 Movement
Type
Material B = 1 due 101 Movement Type.
Here we call 543 Symbolic Return / Return token, that means Vendor is returning material you have sent, but this material was transformed in another one.
