Scheduling dates from sales order not confirmed

Question

Hi All,
I have configured CRM_APO_ECC integration in system. But getting few error on CR$M-APO side. Can you please sugest on these queries:
1. order entered in CRM, ATP check is triggered in GATP & confirm dates & vendor (plant) populated with 2 schedule lines. But when I save the order, I get RED signal on item details tab, also I could not see order in RRP3.
2. Second query is regarding RBA. I have configured location sub rule. But when the qty in initial plant is less, it does not give me the substitute location, rather it proposes me later date considering the checking horizon maintained in product master.
But when I manipulate the same material with error (i.e. by removal of ATP group in product-loc master), and create order for same material, I can see the rule in place when ATP is triggered and can see 2 line items on ATP screen, first showing RED light (for which ATP grp isnt maintained) and 2nd is one with substitute location. In this case, it works. Where is my config missing?
Please help me with these 2 situations.
Many thanks,
AP.

Answer 1

Hi All,
I got answer to this (i.e. query # 2), rule based plant was not available when triggered from CRM.
Now i can see it, Solution is - Activation of preselection activation key. I activated it in APO Requirements profile for CRM & also in Check instructions.
Thus I can see all sub plants.
However, my 1st query is still under search. My scheduling dates are not getting confirmed. Following is the scenario:
initial plant (USA1) has no stock in RRP3, but still showing green & accepting orders:
When I chose alternative plant USA2 where I have stock, 2 scheduling lines are generated, 1 for initial plant & 2nd for USA2. There is no error message till then. And when I hit save, I get availability confirmation error, schedule line is not confirmed.
After saving, only one line item remains, and plant is USA1, i.e. initial where there is not stock.
Can you please suggest what config might be missing?
Thansk,
AP.
