Pur reqs not created based on demand.

Hi All,

we are facing issue with externally procured products in a particular location.

The issue is against the sales order deliveries the pur req's are not getting created.The pur req's quantity is changing and they are getting created based on the demand qty.

The MRP is a background job and once product into a negative stock this automatically triggers a req being created.

But the Pur reqs are not created enough (ex: if del req is -10 the pru req created is 4 some times 3..)

Can anyone suggest why this issue is happening.

Thanks in advance.
