I had done the setup for Automatic Sourcing (BPA, Sourcing Rule, Assignment Set, setting profile option MRP:Default Sourcing Assignment Set, etc.). It gives a release for a BPA when the single Supplier allocation is 100% with Rank 1.
When trying to have two or more Suppliers with different allocation percentages (keeping 100% allocation in totality with same & different ranks of Suppliers in different scenarios), the automatic sourcing is creating release for total requisition quantity against one Supplier's BPA only (Supplier is selected by System based on precedence of rank and allocation percentage).
Is it something system built that Automatic sourcing works for Single Supplier or else may please advise. Thanks.
