RE: Main Project and Sub Project relation
Probably the following example can help you to understand the requirement:
LE-1:
Process:
1.1. Project created for CAR Manufacturing.
1.2. Sales Order
1.3. Master planing
1.4. Purchase Order
1.5. Intercompany Purchase order for CAR BODY to LE2.
1.6. Intercompany Purchase order for Gear Box to LE3.
1.7. After sales support services (AMC) to LE4.
LE-2:
2.1. Create a Sub-project* under the main project Created at LE-1
2.2. Intercompany Sales Order - Sub Project*.
2.3. Master planning - Sub project*
2.4. Purchase / Procurement - Sub project*
2.5. Manufacturing - Sub project*
2.6. Intercompany delivery and Sales Invoice - Sub project*
LE-3:
Same steps as 2.1. to 2.6.
Can you please help me for the above scenarios. Thanking you all in advance.
