Ipek,
But still, they have both receipts as 120 pieces of product A.
No, they don't. Or, at least, there are no receipts showing on your //RRP3 screens.
From your statements, it appears that your intention is to 'somehow' utilize the production capability contained in location HNT_PROD to satisfy the demands found in locations HNT_KUNDE1 and HNT_KUNDE2. Yet, I see no evidence in your statements or in your screen shots that you have defined any method to move materials from HNT_PROD to the demand locations. Without such a definition, you cannot expect CTM (or any other planning engine) to create a solution for you.
Many companies create Transportation Lanes to translate such business requirements into master data that can be used by a planning engine.
