Operation sequencing in R/3 not scheduled

[Former Member]

I have a routing with one operation for a machine. In APO I need to finite schedule both the machine and the operator capacities. I created a second work center for the labor and added a parallel sequence to the routing to start and stop at operation 0010. The formula in the labor work center is the standard for labor capacity and labor scheduling. The execution time for the standard operation, machine time, and the parallet sequence for the labor is the same. But when I use the 'schedule' function in the routing to check the scheduling data the machine operation is scheduled correctly but there is no time scheduled for the parallel sequence.

Has anyone had this issue before, and if so what corrective action needs to be taken or what have I set up incorrectly.

I need for APO to finite schedule both resources. If I create the requirement as a secondary capacity on the work center it is not identified in APO (in the PDS) as a calendar resource. And only calendar resources can be finite scheduled. In this case both the machine and the labor are critial. I cannot over schedule any one machine and I have a limited number of operator capacities. Therefore both have to be finite scheduled. I have 36 seperate machines but only 8 operators. I therefore cannot have more than one order at a time on a machine and no more than eight total orders at any one time due to the limited number of operators.

If I simulate the scheduling in the routing I have duration for the standard operation but nothing for the parallel operation. In the PDS I only see the capacities for the machine and setup operators which are a second capacity in the machine work center, but no capacity for the parallel operation.

If you have a better idea let me know.

Side note - data for parallel operation is not going to the PDS in APO. But that's another issue.

Thanks for the info

I think that parallel sequences are not scheduled by themselves, but take the scheduling from the standard sequence. They only create capacity requirements.

But why would you go for this complication, with 2 parallel work centers, when you can use a key in the work center to define both machine and labor in the same work center?
