Direct Source Determination in Rule Based ATP check Not working

[former_member629801]

Hello All,

For the Rule Based ATP check in Make to Stock,the location determination activity works fine when i select the availability check and No Source determination , then STR get created successfully, But when i select option " Direct Source Determination" with the method as Pur Info Record , then system not able to find valid supplier,but already T Lane is existing

as external procurement relationship between 3812 (destination ) and 3801 ( supplier ), Since the Vendor created in ECC is IV3801 for supplying plant 3801, then i created new T- Lane between 3812 and IV 3801,then it determine the supplier as IV 3801, but after confirming full delivery , it tries to replce the plant from 3812 to IV 3801. Now i ave below question on my understanding

1 Why system is looking for Supplier as IV 3801 instead of 3801 as the PIR cifec from ECC and populated T-lane between 3812 and 3801 instead of IV3801.

2 Is there a way to make the system understand 3801 as supplying plant for IV3801 in APO while check for RBATP.

3 If i have select the STR check box in location determination , then STR should also get create from IV3801 /3801 to 3812 f instead of replacing the plant in sales order.

4 If i try to work for Configurable make to order with Rule based ATP with the above setting ,then it doesnt work it seems except direct source determination

Kindy guide me on this.

Thanks
