2.First i have run the mrp planning mode is normal after that i have some changes in material master , so planning mode is - RE Explode planning & Bom ? AT THE TIME OF MRP RUN  it is correct

3.In background MRP Run at MDBT - what is the PLANNING MODE ?

4. How will work on automatic PO Create through MRP Run PR\S.?

Kindly give me the feedback , i am waiting for your reply.

Hello Uma

1 - A shipping notification is a confirmation from the vendor that the material has been shipped.

2 - When you change your BOM or material master MRP settings, system automatically set a flag on the planning file to re-explode the BOM. Therefore, MRP automatically re-explode the BOM, even with planning mode 1. Planning mode 2 is only necessary when you need to force a new BOM explosion and I don't recommend you to use it frequently, as it may lead to performance issues. See my document for more details.

3 - See notes 206666 MRP: Control parameters during planning and 135788 - Planning mode in material requirements planning.

4 - MRP does not create or change purchase orders or production orders. MRP can only create planned orders, purchase requisitions or schedule lines.

At last, I wrote the following document with links to the MRP FAQ notes, which may be helpful to you:
