Query on planning calendar with reqt from production order reservation

Dear Experts,

I have a semi finished material which is externally procured with respect to a planning calendar(Has lot size - PK in material master). Planning calendar consists of weekly procurement on every thursday.

when an production order is created for its header material and subsequently an reservation is created for the component. Now when we run MRP for this reservation requirement then system is not creating Purchase requisition as per planning calendar period on "Thursday". I checked all the settings in material master and lot size configurations, everything seems to be fine.

Please let me know what could be the issue in this case.

    This kind of issue may happen if you are using a goods receipt processing time, since the periodic lot sizing procedure considers the delivery date instead of the availability date. There is a customizing setting under the lot sizing procedure that allows you to change the system behavior.

    See SAP note 81369 for details.
