Circular Transportation lanes during CTP/PP-DS
We run CTP on our products & provide promise dates to our customers based on the available block dates &/or the dates as feasible from finitely scheduling our resources.
Further, based on the way we do business, we've bi-directional t-lanes defined between plants & have priorities added to the master data in order to avoid unwanted t-lanes from being picked.
What is however happening on & off is that the system seems to be looping between 2 locations multiple times, creating unwanted iterations, during the CTP check. I've seen some fix when this happens on the SNP Heuristic run, however, wanted to know if there is a note or a different fix that I'm missing.
Here is a screen print of the problem -
Those highlighted in YELLOW (Source & Target) are the unwanted t-lanes created by the system. One such route would have sufficed.
