SAP APO SCM - SPP: Kit to stock orders fixed

[former_member1184827]

Hello,

I Need support. We are using the Kit to stock function in SPP for internal kitting. For all Kits "Time for Internal Kit to Stock" is set to 672:00 and Planning Horizon is set to 540. No further Horizons/ Planning time fence is set.

We have the Situation that in "External Procurement - Schedule Maintanance" all planned orders for one product are set on "fixed" up to 540 days in future. For other Kit to stock products no Planned orders are fixed. I deleted all Planned Orders and did a new DRP. Unfortunately same problem.

How can I find out, why I get fixed orders?

Thanks!
