Multi Mix resource - planned order dates not matching

Hi

We are facing planned orders dates mismatch in ECC and APO.

In ECC we have created work center as resource type ‘5’ – Multi mixed resource and its reflected in APO as Multi mixed.

We have 22 hors capacity available per day and number of individual capacities are maintained as 12

So total available capacity per day  = 246 hours

The capacity is showing up in APO correctly.

Also, in rate routing ‘required Splitting’ check box is ticked.

When planned order gets scheduled in ECC, system considers 264 available hours in a day and schedule planned order accordingly.

Problem is when plan order CIFed to APO, the days are not matching in ECC and APO.

Please suggest if we are missing any setting related t Multi Mix resource functionality.

Thanks in advance for your help!

Regards

Yogi
