How replenishment lead time is getting calculated

[RaghavanKathamuthu]

I have kept this configuration in OPJJ for RLT calculation as per Link 

For F type materials - External procurement the calculation working properly

RLT = Purchasing processing time (OPPQ) (Working days) + Planned delivery time (Calendar days) + GR processing time (Working days) if planned delivery times comes on holiday then moved to working day.

In my case 1 + 6 + 1 = 8

Also here how the Delivery date calculated?

Then For E type - Inhouse production its not working.

RLT = In-house production time (working days) + GR processing time (working days) or

RLT = Total replenishment lead time (working days) (MRP 3 View)

In my case I maintained TRLT = 3 days

Here the system should propose the planned order start date as 19.12.24 but instead 27.12.24. Its not considering the Total replenishment lead time.
I have ran the MRP in MD01N with scheduling mode as 1 - basic date scheduling.
Why system proposing like this?
Please let me know if I am missing any.

TRLT in MRP 3 view is not affecting the scheduling . Its just used in sales order ATP.

Hi,

can you please check what was your scheduling parameter during the MRP live run, please use the indicator 1 and check it back !
