MRP Planning Worksheet - variable production order qty

eedobson

Hello all -

I have a process industry client with long lead times and variable production order quantities. The demand comes from sales orders + forecast, but quite often they apply a complex manufacturing formula (done outside of NAV) to determine the production order quantity to optimize use of their key raw ingredient. So we want NAV to do an initial rough cut quantity estimate based on demand, then typically the client will round it up based on the manufacturing formula. (The excess amount is just put into inventory).

But once the production order quantity is determined, we don't want NAV to keep telling us to change the quantity to what it thinks we should produce based on the planning parameters. Because of the long lead time, using the planning start date to exclude these production orders won't work.

Ideas on how to stop the Change Qty action messages (and then pushing the lower demand down to the raw materials)? Thank you in advance!

You can use column Planning flexibility on Production order line.
If you set up Planning flexibility to None, planning system will not offer you to do any changes on those production order lines.

But i think you should set this flexibility to NONE before you create production order. It means before you Carry out action messages in Planning worksheet.

That's perfect, thank you! I didn't know about that field.

Just curious why you're suggesting doing it before I create the production order. I've tried toggling it back and forth on the production order after it's been created and Planning seems to respond correctly.

It's up to you, but you said this: "we don't want NAV to keep telling us to change the quantity to what it thinks we should produce based on the planning parameters"
If you set flexibility to none before creation at planning worksheet line, you will never see this row (prod order line) in planning worksheet again. I think this is what you need.

Mark as resolved?
