Enhanced R30890 with P30890 does not allow copying to the same B/P

I just tested the newly enhanced R30890 to be used with P30890 to define several B/P to "Copy to" from a reference B/P.

I realized it is not possible to define the same B/P ¨From¨ and ¨To¨.

We are using future cost method (05) to upload massively new standard costs (07) but we are unable to copy cost components from one to another cost method because it is not possible by means of P30890.

The option to copy from processing options in R30890 allows us only to copy one single B/P and we habe thousands of B/Ps.
