Situation:
- there is a valid blanker order. Its released, has an ending date that is not before the current date. There is an open qty in the line.
- run planning worksheet and create a PO (for which you have a blanket order).

At the moment this new PO line is not automatically linked to the blanket order. You have to do that manually.
Please automate this so that the purchase order line will be linked to blanket order line.

Please add the following checks:
- it is should not be possible to create a POs with a higher qty than the open qty in the blanket PO.
- the total value of the PO line can not be higher then the open amount on the blanket PO.
- supply dates after the blanket PO ending date (or before the blanket PO start date)can not be accepted (give a warning).
- the item card should be checked to see if the vendor is the same as the vendor in the blanket order.
