Uploading Production Requirements For Finished Goods From External System To Run MRP For Components in SAP.
Hello Production Planning experts,
I'm looking to solve the current business problem:
The company bought a third party software (JD Edwards) to calculate production requirements instead of using SAP's standard Production Planning or a tool like SAP's APO. They run a batch job to query Sales Orders, Deliveries, available stock, stock in transit, etc. from sap and feed/upload it to the third party software so it can calculate the Finished Goods Production Requirements for them. They love the third party software, so replacing it is not an option. Since the third party software is already taking into account Sales Orders, Deliveries, available stock, stock in transit, etc. from SAP, it just outputs a "Finished Goods Production Schedule" by week.
My questions are:
1) What's the best way to upload something like that in SAP in the form of Planned Orders or something of that nature?
After i get that schedule in SAP:
2) Is there any way to calculate components' requirements for that "Finished Goods Production Schedule" alone? The company would like to IGNORE existing stock AND expected-goods-issues in the future (sales orders, deliveries, etc) for Finished Goods ONLY. The components calculations would work the standard MRP way, taking into account existing stock and AND expected-goods-issues in the future (sales orders, deliveries, etc)
I started looking into Master Production Schedule (MPS), but I don't know if that's the right approach since I'm not very familiar with it.
Thanks in Advance! I will gladly reward points for helpful/correct answers.

I suggest you to upload your production plan in the for of "Planned Independent Requirements" using BAPI BAPI_REQUIREMENTS_CREATE. Later, MRP will create planned orders to cover the PIRs.
If you don't want to consider the existing stock of the finished product, you should use the planning strategy 11 to create your PIRs. Take a look on the following link for more details about this planning strategy:
Here you will find the following information:
The make-to-stock strategy gross requirements planning is particularly useful in mass production environments; it is often combined with repetitive manufacturing. This strategy is particularly useful if you need to produce, regardless of whether you have stock or not. For instance, steel or cement producers might want to use this strategy because they cannot shut down production; a blast furnace or a cement factory must continue to produce, even if this means having to produce to stock.
This strategy is also frequently used if there is a Material Requirements Planning system in a legacy system that needs to be linked to an SAP system which serves as a production execution system. The legacy system calculates a specific production plan, which has to be executed, regardless of the stock situation in the SAP system
It looks like this planning strategy is exactly what you are looking for.
