Process chain -Loading data into Process chain

I have a perfect process chain - that delivers quantities after a MRP run- I want to test with single material,the material is assigned with BOM,ROUTING,W/C,PDS, Production version in ECC

I am cifing it to APO and in RSA1 I want to run the process chain in Delta mode that is for single material.

Now How will i input the Master Data- the process chain should be made to read the Master data and deliver the Output quandities

Basically I want a input data to process chain by some means,Should i create a Infocube?? , pull the master data into it.?? and link infocube and process chain

Please give me some valuable idea
