Dear Sandeep kumar praharaj
Following are the steps
A. Configuration
SPRO --> Production --> Materials requirement planning --> Master Data --> Independent Requirement Parameters --> Planning Strategy -->
1. Define strategy
Use Planning Strategy = 20 (Make-to-order production)
It will be tagged to requirement type KE
2. Strategy group for 20
Use Main Strategy = 20
3. You must have created your Plant <WERKS> and MRP group <MTART>
Select combination of Plant, MRP group and assign planning strategy group = 20
B. Master data/Transaction data
1. Create material with Strategy group = 20 in MRP3 view
2. (Sales Department) Creates Sales order for the above material
3. (Planning Department) Runs Make-To-Order planning (MD50) by putting in sales order and sales order item
4. (Production Department) get planned orders which can be converted to Production orders
