Launch Supply Chain Planning Process - Significance of Anchor Date

Question

While Launching plan, there is a parameter Anchor date. It defaults to current. We can change this to any past date. What is the significance of this?
Our client has a requirement - They want to see the forecast demand for current month (though today's date is 6th Mar, they want to see from 1st Mar). I tried changing Anchor date to 01-Mar. This did not pull past data.
Past forecast is pulled only when I change "Past Due Forecast Days" in ASCP Parameters.
Can some one exaplain what change is supply/demand we can see by changing anchor date?
Thanks,
Anitha.

Hi,
for what I saw many reasons can cause this kind of stuck.
1) Check if there are some locks on the MSC tables, maybe is the reason why it does not go through.
Usually the concurrent (I suppose you are stuck at the memory based snapshot) creates a BIG log file. Check if the log file goes on.
2) Once the Snapshot was incredibly slow due to some loop in the BOM. Since you are working on process manufacturing the loop should be in the recipe. You should see if there is a loop in the log.
3) Stop the concurrent if he goes beyond any acceptable time and try to create a very small plan, with just few item, a week of planning time and one demand. Try to use some dummy supersimple data. If the plan goes fine it means that probably you have some issues on the data you feed the system. (i.e. Loop or too much things).
4) I am not sure if this apply but maybe you have some sort of limitation on the maximum number of concurrent that can run simultaneously. We had something similar and if I well remember some concurrents where waiting for other to finish but the others could not start do to a limitation on the maximum concurrent. (check in sysadmin for this).
Hope it helps
