Base Planning Object

Question

Hi Everyone,
Which method do we use in which situation?
1) Base Planning Object
2) Cost Estimate with QTY Structure
3) Cost Estimate without QTY Sturcture
And check this as well...
If you plan a new product for which there is no master data in the SAP, you can perform initial planning and cost projections by creating a Base Planning Object
What exactly SAP refering 'master data' in the above sentence. That is copied from their reference book.

HI,
1. Base planning object allows you to enter a quantity structure manually, so you can costs without accessing BOMs, routings etc.,  With this you can cost new products (without material master). It is like a master record (with your own name) for which can create a cost estimate. It is excel like sheet where you can enter you costs. You still refer to a Costing variant here which is not the normal cost variant, though.
2. Cost estimate with quantity structure makes use of quantity structure (BOM, routing etc.,) maintained in SAP. Costing view of material master has reference check to costing with quantity structure.
3. The material costing without quantity structure is designed to cost materials without accessing BOMs and/or routings. The costing results are written to price fields in the material master. If no BOMs or routings exist, you can create the quantity structure manually and valuate it with the cost estimate.
If you are essentially trying to understand the difference among these in terms of usage, I think this makes it clear.
Hope this helps.
