JBA ML - MRP and DRP

[Stuart Sandler <SSandler@xxxxxxxxx>]

We are using both MRP and DRP and have discovered a problem that I wondered
if anyone else had encountered.

We use DRP only to transfer goods from stockroom to stockroom (for example
from our stockroom in Tucson to one in Canada). In the past, we used sales
orders with no selling price, but had to do monthly journal entries to
reverse the costs. When we upgraded to System 21, we purchased DRP to
eliminate this.

Now, we have found out that System 21 MRP does not see 'DRP' orders as
supply, but rather as demand. In other words, if we have a requirement for
30 widgets, and happen to have 15 in stockroom 10 and then create a DRP
order to transfer them to stockroom 01, MRP thinks that we have a demand for
45 and tells us to order that many, instead of seeing the 15 in stockroom 10
as a potential supply.

I turned this problem into the GEAC help desk, thinking we had simply set up
something incorrectly, but they confirm that DRP and MRP will not work
together in this type of example.

If any of you have any suggestions, or if you have encountered this and have
an idea, I would appreciate hearing from you.

Thanks in advance.
