Purchase Requisitin not automatically created at the network level

Hello,

We are facing an issue in the CJ20N

Project- WBS- Network Order- Activity- Materials are attached to it

For ex- Material number 23 is added to the network as per the business process the Purchase requistion will automatically get created.

Now we are facing an issue.

When we add the same material to the activity, the purchase requistion is not created auotmatically, we are not able to view the purchasing data tab.

The moment we add this material, it's stating reservation for network.

Previously it was showing up as purchase requistion for network.

Please help us in knowing what could be the possible reason for this behaviour.

Regards,

prashanth
