Deafult Order type for APO planned & process order

Hi All,

I'm trying to convert APO planned (PP/DS) order to process order but it is ending with error code 164 & 165 in CCR report.

By default the system is picking some order type for which the master recipe is not configured.

I just want to know the link in customization between ECC & APO where it is defined that when planned order is created in APO & while converting to process order should get assigned a order type.

Thanks in Advance.
