lead time scheduling for dependent requirements

Dear Experts,

Scenario is

The BOM consists FG next level SFG1 and next level SFG2

MPS carried out for FG. Our requirement is Plaaned order for FG, SF1 and SF2 should have same basic dates and Production dates should same and by considering forward scheduling all planned order start time should 6.00 ( shift details are maintained in WC)

and all process order should have start on the same date at 6.00.

Currently I am able to get for header item . but not for depedent requirement.

Please let me know settings

Regards

Sandeep
