When you run material requirements planning in Business Central, the planning worksheet template you choose determines whether the system takes your existing planning suggestions into account. If you forget to enable the right settings, you risk seeing the same suggestions appear again and again, even after you have already acted on them.
To avoid duplicate planning suggestions, your template must have Include Sales Order Handling and Include Planning Line enabled. These settings make the system look at the lines you have already moved to the requisition worksheet and the sales order handling worksheet, so it does not propose them a second time.
How the Include Sales Order Handling and Include Planning Line settings work
When you calculate the demand for moving production, open the template you are using and make sure both options are checked: Include Sales Order Handling and Include Planning Line. With these enabled, the calculation gives you a fresh and correct view every time you run it, because it takes both the planning lines and the sales order lines into account.
What happens when you calculate the first time
The first time you calculate with the template, both the requisition worksheet and the sales order handling worksheet are empty, so the system calculates everything from scratch.
You then accept the action messages and carry out the suggestions. This transfers the lines to two places: the requisition worksheet and the sales order handling worksheet. From there, you act on them. The sales order handling tells your sales assistant what to move, and the requisition worksheet holds the lines you need to work on yourself.
Why the same suggestions can reappear the next day
The day after, you run the calculation again with the same template against the same data. The system should take the lines you already suggested into account so they do not show up a second time.
If you do not carry out a planning line in the requisition worksheet, and you do not carry out a sales order line, those lines stay open. With Include Sales Order Handling and Include Planning Line enabled, the system knows they are already pending and leaves them out of the new run.
In practice, you may still see a new production order appear. That happens when a line you transferred into the requisition worksheet created additional consequences downstream. The lines you already handled, however, will not show up again.
Q&A
Which settings must be enabled in the planning worksheet template to avoid duplicate suggestions?
Enable both Include Sales Order Handling and Include Planning Line. These make the calculation take your existing planning lines and sales order lines into account, so suggestions you have already acted on do not reappear.
Why do the same planning suggestions show up again when I recalculate?
Because the template does not include the existing planning lines and sales order lines. Without those settings, the calculation ignores what you have already moved to the requisition worksheet and sales order handling worksheet, and proposes the same lines again.
Where do the suggestions go after I carry them out?
Carrying out the suggestions transfers them to two worksheets: the requisition worksheet, which holds the lines you work on, and the sales order handling worksheet, which tells your sales assistant what to move.
Why does a new production order appear even when I expected no new suggestions?
A line you transferred into the requisition worksheet can create additional consequences elsewhere, which generates a new production order. The lines you already handled will not reappear.
