How to include not firmed receipt elements (PRs) in the LTP

Hi Experts,

I have ran the LTP MRP using a particular planning scenario, but the results doesn't show any Purchase requisitions, Planned Orders, etc in the long-term window. It shows only firm receipt elements like Purchase Orders, Production Orders only. Any reasons behind this? How to include not firmed receipt elements in the LTP long-term window?

Thanks

Raj

Hi Ayethebing,

thanks for the update. But without firming the demand from the other plant, I am interested to know some other work arounds. Is there any user exit or enhancements can be done to copy the un-firmed external demand (PRs) from operative MRP to LTP MRP?

If possible, what are the pros and cons?

Thanks

regards

Hi Experts,

any update on this issue as it is still not resolved? The actual issue is that the un-firmed demands generated from another plant (through sourcelist settings as default supplier plant) in the form of PRs and its corresponding Plan Orders are not showing in the supplying plant's LTP MRP results. Only the firm demand (POs) from external plant and the related Plan Orders are showing in the LTP MRP results of the supplying plant. Any possibility to include the un-firmed demand also in the LTP?

Thanks

Raj.

There is no standard way to include un-firmed planned order or PR from operative planning to LTP.

Two ways to work around,

1. Include another plant in your LTP planning scenarios. Run both plants therefore, the simulative PR are created and send the requirement to supply plant.

2. Set the material master at another plant with MRP Type P1. The planned order is firmed automatically if it is within planning time fence. Therefore, it becomes firmed demand in your supplying plant.

Please consider.

Hi Vivek, Ayethebing,

thanks for the reply. The reason is that the planning side want to closely monitor weekly supply / demand situation using individual LTP scenarios for the individual weeks. This means, they can see what are the firm and not firmed receipt elements and the corresponding demand for the individual weeks using a particular LTP scenario and can compare it with another LTP scenario at a later week. This is something like a snap shot of a particular week that shows the supply demand situation and any changes in the supply / demand can be spotted easily.

In the operative MRP, it is not possible to capture weekly snapshots as it is very dynamic. So the business want to include not formed PRs / Plan Orders also in the LTP, any possibility?

Thanks

The reason is if you set to include every firmed MRP elements, and use current stock. The result is the same as run MRP again in normal mode. Planned order not firmed will be deleted and/or change according to new planning situations.

There is an option to compare planning scenario to operative mode, and copy from LTP to operative mode in MD43 - MRP Single-item, interactive.

Rgrds,
