‘This is my behavior’, says CTM

Just wanted to share the behavior of CTM – comments/corrections are welcome 😉

I don’t want to explain more here – just would like to show to you in a simple manner. The only thing you need to know is – CTM goes deeper and deeper until it finds the required receipt element (say, stock) for negating the demand. If nothing found, it ends up creating a planned order at the plant (of course, based on your master data selection again).

Supply Chain:


CTM Behaviour:


But then, I think you cannot appreciate this behavior of CTM. For example, if there is enough stock to fulfill at R2, it still searches still PLANT1. The ideal/expected behavior would be:

search for R1, if not – go for R2.

If both R1 or R2 fail, go for WH1, and then to WH2 and so on…

Basically, the expectation is: let it search node by node, why go deeper into the node? Right! You can force the CTM to behave this way – all you need is to activate the below check-box.


But then, for this to work – you need to activate the corresponding business function which you can find at the below place in SPRO – by the way, activate it at your own risk – it is risky (you need to assess the impact before you do that – like how does it impact on the existing profiles).

      If you need the demand to consume stock available at R location, you can run CTM for stock only (don't create any order) so where ever it finds the stock demand will be fulfilled. The 2nd way is to run CTM, first only considering R locations and then considering whole supply chain.

      CTM behaviour is it picks the first optimal solution and not the best one like optimizer,

      yes, you can filter out based on the master data selection of course (your 2nd way) 🙂

      With 'supply consumption' function, I think we can reduce the number of profiles - this again is based on the business scenarios of course.
