Circular Reference - Supply Planning

Hi,

For a customer of ours we're building a Supply Planning model on daily basis.

When trying to build the core module I'm running into a circular reference which I can not seem to solve.

Any help would be greatly appreciated.

Relevant line items are shown in the screenshot below.

For the Suggested Reorder Quantity the formula should be to take the Reorder point - Ending inventory - MOVINGSUM(Scheduled receipts, 1, Supplier Lead Time) - MOVINGSUM(Planned Receipts, 1, Supplier Lead Time -1).

However the Planned Receipts are calculated based on the Suggested Reorder Quantity, which you will theoretically order. Formula goes as follows: OFFSET(Suggested reorder quantity, -Supplier Lead Time, 0).

I've tried a myriad of ways to workaround it but can't seem to make it work.

Hope anyone can help, glad to jump on a Teams or provide extra information where necessary.

Thank you!

Hendrik

Hi Hendrik,

Can you please show the 'Referenced By' for the Line Item - Suggested reorder quantity

Hi,

It's referenced by the Planned Receipts.

Great!

But I'm still a little confused, what is the formula for Planned Receipts? Is it the one in the original screenshot or is it: OFFSET(Suggested reorder quantity, -Supplier Lead Time, 0)

Can you first change the formula in Planned Receipts to OFFSET(Suggested reorder quantity, -Supplier Lead Time, 0)

and then apply

Reorder point - Ending inventory - MOVINGSUM(Scheduled receipts, 1, Supplier Lead Time) - MOVINGSUM(Planned Receipts, 1, Supplier Lead Time -1) to Suggested Reorder Qty

Hi,

The full formula for Planned Receipt is as followed.

IF OFFSET(M Supply Plan Custom Days.'Days you Order this SKU 0/1'[SUM: M Custom Day Mapping.Standard Day Running], -'M SYS - SP7 - SKU / DC / Supplier'.lead time, 0) = 1 THEN OFFSET(Suggested reorder quantity, -'M SYS - SP7 - SKU / DC / Supplier'.lead time, 0) ELSE 0

As in the model we have an Ordering Calendar which is the 'Days you Order this SKU', therefore you have to look back if Today - Supplier Lead Time would be an Ordering Day than we would have Planned Receipts.

Hope this clarifies, thanks for helping!

Thanks, I'm guessing Planned Receipts isn't what is causing the circular reference.

Can you share the formula and referenced by for Scheduled Receipts?

Hi,

This comes from out of a data module.

Good to know is that the Supply Plan is on Dynamic time (List created with only working days)

Would you prefer jumping on a WebEx or how can I help you to solve this together?

Thanks!
