Dear All,
As per my client's requirement, we are adding Materials and services in CJ20N to the network & activities and creating material Purchase requisitions and Service Purchase requisitions. MM has created 2 different PR document types for materials and services. From the T-code: OPTT I have to select the PR document type. Here it shows only one document type selection option.
My question is how to link 2 document types for material PR and service PR automatically

Thanks
Kumar
