How come Incoming Orders Qty is not getting updated when allocation sequencing is used

We have a requirement to check allocations at two different levels (customer/material) and (customer/category).  We will only check the second level if the first does not have any allocation available.  We have created two different planning areas, two different allocation procedures, and two different allocation groups to accomplish this.  Here is how it looks.

Product Allocation Group

ZGRP1 (characteristics – Customer / Material)

ZGRP2 ( characteristics – Customer / Category)

Product Allocation Procedure

ZPROC1 – Cumulative, assigned to ZGRP1 with a Factor of 1

ZPROC2- Cumulative, assigned to ZGRP2 with a Factor of 1

Sequence of Product Allocation Procedures

ZSEQ

Procedure List

        ZPROC2

Maintain Connection to Planning Area

ZGRP1 is connected to ZPA1 (Customer / Material Level)

ZGRP2 is connected to ZPA2 (Customer / Category Level)

Master Data Settings (ATP tab)

Alloc Proced. - ZPROC1

Procedure Seq - ZSEQ

The configuration works perfectly when the sales order checks and passes allocations on ZPROC1.  The sales order passes atp and the planning book (and PA group) is correctly updated with the Sales Order Incoming Quantity.  The issue that we are having is when sales order allocations cannot be met using ZPROC1.  The logic correctly steps through the sequence and looks at ZPROC2.  From the order you see the following, which shows it’s correctly following the logic.  You see that it confirmed ATP allocations based upon ZPROC2.  This issue is that the confirmed incoming sales order quantity never makes it into the planning book and PA group when passing atp for ZPROC2 using the sequencing logic. Also, there is not Product Allocation TQA for ZPROC2.

Allocation Procedure     Open Quantity  Confirmed Qty  Remaining Qty  Proportion %     Checked

ZPROC1                                40                           0                              40                           0                              “Check Mark”

ZPROC2                                40                           40                           0                              100%                     “Check Mark”

By the way we have checked the option in both allocation groups to (check planning area).

Also, we have tested that the allocation incoming number successfully passes atp and updates the planning book when using both procedures separately.  It just won’t update the PA group and planning book with the incoming order quantity when using sequencing.

We would appreciate any help you could extend. Thank you.
