How to configure to run SNP that creates only PReq and Stock Transfer only?

Question

Hi all,
I am very new to SCM.
Please help me on the scenario like this:
-There are 3 Distribution Centers (DC): 2400, 2500, 3800 and a Vendor: 1003.
-Each DC can take products from otherDC. But only DC 2400 can directly send purchase requisition to Vendor  1003 when no stock at all DCs.
-There is a Forecast released from Demand Planning to SNP, that is 1000 products at Distribution Center 2400.
-I will run SNP Heuristic (or Capabable to Match or Optimization) to cover this demand.
-Usually, SNP can create: Purchase Requisition, Stock transfer Requistion, and Planned Order.
                     But I only want the SNP to create Purchase Requisition and Stock Stransfer only.
The question are:
1.In which situations (tock situation,u2026) the system can create Requisition and Stock Stransfer only ?
2.I need create a new Supply Chain  Model (Model) and a new Planning Version from scratch. How can I configure the system (Transportation lanes, Product Master Data, Procurement type in product masteru2026) and make it run to satisfy this scenario?
3.Do I need setting differently for each SNP method ( Heuristic, Capable to Match, Optimization)?
Thanks very much for your support.

Dear Mr. Aparna,
Thanks for your quick reply.
Now I haved created a model like the scenario with product T-F204 and can run. ( I do not use vendor 1003. I created the Plant 1000 instead). But as you said, when I run with SNP Heuristic method (Network level), the system alert:
  u201C Error exist in Locationsu2019 processing sequence for product T-F204u201D
However, I search internet and found a book about CTM. It also discuss about this and the solution as below:
u201CRecursive Replenishment
When using complex supply chains, with many locations and various directional
supply routes, it can be easy to confuse a level-by-level planning tool. In certain
situations, recursive planning can occur. Recursiveness, is when the planning
algorithm is thrown into a loop (circular replenishment). Location 1000 can ship
to location 2400, and location 2400 can ship to location 1000. Situations such as
this can cause the CTM engine to terminate since it cannot find a starting point.
 The solution: Reduce to number of muximum consecutive transport order chains.
Within the CTMProfile, Settingsu2192Master Data Settings tab, planners can control
the sources of supply for External Procurement. With the parameter Maximum
Number of Consecutive Stock Transfers, you determine how many consecutive
stock transfers CTM planning can create. This value does not restrict the total
number of stock transfers for a demand. If you enter a value here, you can prevent
the system from transporting the receipts for a demand over several locations due
to the procurement priority. Also, you must have modeled the master data in such
a way that a direct stock transfer is possible if the system ignores the procurement
priority. If a direct stock transfer is not possible, CTM cannot fulfill the demand.u201D
Currently, our system runs only with Heuristic. It could not run CTM and Optimization so I could not check.
My questions are:
1.     Is the solution of the book can apply for my bi-direction transportation lanes requirement?
2.     If it is true, with my scenario, what is the best u201CMaximum Number of Consecutive Stock Transfersu201D I can set?
3.     How can I model u201Cthe master data in such a way that a direct stock transfer is possible if the system ignores the procurement priorityu201D?
