Integration SAP PPM with SAP PS

[Massi_Merc]

Good Morning,

I am facing a problem with the integration between SAP PPM and SAP PS or when a WBS is created in SAP PS the number ranges that I put on PPM are partially used:

As you can see from this picture I put a number 1010.I22.002.1 on the first level in PPM, but on the lower levels even if I change the number during creation SAP continues to take this number range that is used in SAP PS.

Therefore, my question is, how can I cange the number of lower levels (phases and tasks)? allowing SAP to continue a typical WBS structure. My desire would be to see:

1010.I22.002.1

1010.I22.002.1.001

1010.I22.002.1.001.2

Thank you for your availability!!!
