I have faced this problem in my job.
Our manufacturing department use to produce one material for all plants that need to be sent to other plants.We are doing it with stock transfer order. But there is one problem we are facing while that material is getting back flushed it is showing the unrestricted use by MMBE but while creating delivery of it, system is flashing ZERO item is available.
We have checked the open schedule for delivery also it is ZERO. But even it is not allowing we have check the material master availability check that was 01for MRP control but we have changed it to KP also but even though it is not happening.
But after 2 days it is allowing to make delivery without any changes.
What can be reason? please suggest.
The way today the dispatch did was extra material back flushed and then it had allowed to make delivery.
When you create STO and delivery check weather qty is getting confirmed according to your delivery schedule date
If not check the delivery time for that material in info record or MRP details
reward if useful
