SAP MII OEE - Order Download Error (IDOC Processing)

Dear Experts,

We are on NW 7.5, MII 15.1 SP2 Patch 11, OEE Component 15.1 SP2 Patch 06. ECC on HANA with EHP10

Currently I am in process of setting up the MII OEE demo on our internal box and I have completed all the master data setup both on ECC and MII side.

So far I have triggered all necessary IDOC's from ECC such as Materials, Work centers, OEE Plant Hierarchy etc. and they all have processed successfully in OEE queue. Now when I trigger Production Order IDOC using POIT, MII queue processing fails with below error

[STEP = STD_PRE_XSLT]. Components for the order could not be found; Ensure that all the materials being used are sent from SAP ERP

This is test ECC system so hardly have 3 Materials of which one is component and all of them are already downloaded successfully to MII OEE before trying to download Order and I also checked the Order IDOC and it does have Component information.

Please advise if I am missing any configuration in either ECC or MII side to resolve this issue.

Any guidance is deeply appreciated.

Regards,

Adarsh Sidnoor
