Question about lot size FX

[sap_2605]

Dear SAP gurus,

We are in SAP ECC 6. We have requirement that when we running MRP we will always generate PR with qty = 1.

We thought that we can solve this by using

MRP type = PD

Lot size = FX

Fixed lot size = 1

but apparently it is not.

The case:

We create 3 STR requesting material A to be transferred from plant X to plant Y

STR 1 --> requesting 1 pcs, required date 01.06.2015

STR 2 --> requesting 2 pcs, required date 02.06.2015

STR 3 --> requesting 3 pcs, required date 03.06.2015

In plant X, we set like above:

MRP type = PD

Lot size = FX

Fixed lot size = 1

but apparently it is not.

When we run MRP we expect to have 6 PR:

PR 1 --> to procure 1 pcs, available date 01.06.2015

PR 2 --> to procure 1 pcs, available date 02.06.2015

PR 3 --> to procure 1 pcs, available date 02.06.2015

PR 4 --> to procure 1 pcs, available date 03.06.2015

PR 5 --> to procure 1 pcs, available date 03.06.2015

PR 6 --> to procure 1 pcs, available date 03.06.2015

But then the actual result is this:

PR 1 --> to procure 1 pcs, available date 01.06.2015

PR 2 --> to procure 2 pcs, available date 02.06.2015

PR 3 --> to procure 3 pcs, available date 03.06.2015

So I wonder what is the difference between lot size = FX vs EX (lot for lot). Is there something that I miss in here?

Best regards,

John
