EF consumption with Ehp6 business function "PSM_FM_LOC_CI_01"

Dear Expert,

we've activated  business function "PSM_FM_LOC_CI_01" - https://help.sap.com/saphelp_dbm800/helpdata/en/68/f31c5686c14ba9ae9c47b943b60e3c/content.htm?frameset=/en/68/f31c5686c1…

Now we observe a strange invoice verification   in the consumption history of the earmarked funds.

Example 1

EF consumpion is ok

Example 2

PO consumed by invoice but there is no separate row for invoice in the consumption history of the earmarked fund.

Is it a bug?

Regards,

eccits.
