Here is my scenario in the sales order.
1. I have to do availability check for a material.
2. If the material is not available in one plant, and if it is available in different plant of same company code.
We do the stock transport order. Material should come to initial plant, bcs i do assembly at the initial plant location.
3.If the material is not available in other plants too, i should create 3rd party order for this line item.
Now my question is In the saels order, where can i see how we are procuring the material? Whether is STO/ISTO/3rd party Etc
