3414797 - Alternative sequence is missing in planned order. 

Create routing with alternative sequence per lot size. 
When creating production order, it works fine and the alternative sequence is adopted.
However, when creating planned order manually or by MRP with detailed scheduling, the alternative sequence is missing. 

SAP S/4HANA Cloud

1. In SSCUI 102431 (Define Order-Type-Dependent Parameters for Production Orders), for the production order type, the indicator 'Sequence Exchange' has been set as '1' ( Always automatic selection by lot size of alt. sequence).
2. Create a routing with alternative sequence per lot size.
3. Create production order, the alternative sequence is adopted per lot size without any issue.
4. Create planned order manually or by MRP with detailed scheduling, in the 'detailed scheduling' tab of planned order, the alternative sequence is missing. 

There are 2 possibilities.

1. Go to SSCUI 101176 (Define Order Types for Conversion to Orders for Plant) or 102818  (Define Order Types for Conversion to Orders for MRP Group) to check the 'Order types for the conversion'.
   The order type maintained for production order is different from the one in Step 1 mentioned above.
   
   
2. If there is no standard values (e.g. Setup time) maintained, even if alternative sequences are adopted, they will not be displayed in planned order. 

1. Cause 1 :
   For this case, either change the order type to the one in Step 1 or set indicator 'Sequence Exchange' to '1' for this order type as well in SSCUI 102431.
2. Cause 2:
   Maintain the standard values in the  operation in the alternative sequence then create new planned order .
