3360455 - MTO reference number is taken from the sales quotation instead of sales order

When a MTO process is created with a sales quotation, the sales quotation number instead of the sales order number is used as reference in the planned order.

This is caused by system configuration. 

• This behaviour is controlled by the requirement type. 
• Currently the Requirement Type is determined using the Material Master Strategy (MRP 3 Tab) first which is currently B6 for the Demo Material FG228 and will result in Requirement Type BB6.
• See Quotation Procurement Tab below:
  
• In order to have the Sales Order as as the referenced document for the Planned Order this needs to be set/determined to S46. For this the SSCUI 105120 "Determine Requirement Type by Item Category and MRP Type" can be adjusted:
  
• The current blank standard content for Src evaluates to 0 which means the Material master strategy is considered first.
• By setting it to 1 - Item Category and MRP Type the underlying table of the SSCUI is taken for the Requirement Type determination and evaluates to S46.
  
• With this the Planned Order should reference to the Sales Order it was created for.
