Scheduling failure ...

Question

We are getting this error message while scheduling : Scheduling Failed as the required item or one of its components is not collected.
We have entered the item c*1234 at the order line and booked the order. the order line says booked and then when we try to Schedule the order line for this item ..we get the error message
The basic setups are :
profile INV:Capable to Promise is setup with value as ATP/CTP Based on Planning Output
The item hierarchy is as followed :
Item A (PTO item)
Item C (ATO item )
c*1234 ( Config Item )
c1
c2
c3
c4
BOM related setup in the shipping organization org1 :
The BOM for the item C has the components c1 , c2 , c3 and c4 defined under it.
The BOM for the item c*1234 has the components c1 , c2 , c3 and c4 defined under it.
Item Master related setup :
For the PTO Item A we have the ATP_FLAG as N while ATP_COMPONENTS_FLAG value as N
For the ATO Item C we have the ATP_FLAG as N while ATP_COMPONENTS_FLAG value as y ( material only )
For the Configured item c*1234 we have the ATP_FLAG as N while ATP_COMPONENTS_FLAG value as y ( meaning the scheduling for this config item would be based off the ATP calculation for its components )
For all the component items ( c1 , c2 , c3 & c4 ) we have the ATP_FLAG as Y while ATP_COMPONENTS_FLAG value as y and appropriate atp_rule is populated.
Now we have created an order with item c*1234 entered on it. then we book the order and see order line status
goes to Booked with the shipping org as Org1, but the Schedule ship date is Blank. We try to Schedule this order line for this item it says
Scheduling Failed as the required item or one of its components is not collected.
We checked in the msc_system_items table for plan_id = -1 (data collection) as we as for plan_id for the ATP Plan,
the component items c1 , c2 , c3 & c4 are collected for the master inventory org as well as shipping organization org1
But for the config item c*1234 in the msc_system_items we see entry only for the master inventory org but there is no entry
against the shipping org Org1.
Could someone please suggest us as to what could be issue here or what setup needs to be done

Answer 1

1. Yes forecast control for the option class items is set to : Consume & Derive while for the Option Class this is set to Blank & FOR THE C* configuration item the Forecase control is set as Blank
2. Regards the Planning flags : option class items : MRP/MPP Planned with End Assembly/hard pegging , for the C* item as well Planning method MRP/MPP Planned with End Assembly/hard pegging
3. Regards the ATP flags :
for the option class items : Check ATP : material only , atp rule : is defined as well , ATP Components : material only
for the C* Configuration item : Check ATP : material only , atp rule : Blank , ATP Components : material only
The issue is happening when only the C* item is put on the order line directly and then scheduling doesn't happen. we are not getting what is the issue here
If we configure using the PTO Model , ATo Model and components and then get the C* item ..then this scheduling happens fine.
thanks
