Collective orders confirmation and serial numbers

[lucchini_21]

Hello SAP experts,

While using Special Procurement Type "52-direct production", I cannot confirm the materials with serial numbers that are in sub-orders (which are not in the principal order).

Example:

0- Material A is in the principal order and it has a serial number

1- Material B is directly produced for Material A and Material B has a serial number

2- Material C is directly produced for Material B and Material C does not have a serial number.

In this case, I can only confirm the production order of Material C. However, I cannot do it for Material B because it has a serial number: SAP message C2206.

If Material B did not have a serial number, there would be no problem: I would be able to confirm the production orders of Materials C and B by tCode CO15, and Material A by tCode MB31.

Given that I am constrained to have a serial number for Material B, are there any potential solutions to this technical issue?

Thanks in advance
