Hi, experts.
How does valies assigned to fields Menge an BETRAG.

During the posting it goes to MM07MFF9_F_SEGMENTE_GENERIEREN 

inside  ENHANCEMENT-SECTION     F_SEGMENTE_GENERIEREN_02 SPOTS ES_SAPMM07M. 

The fields are filling with strange values ( MENGE = 1.2000000000000000E+01, BETRAG = 4.9000000000000000E+01 ) 

And if there an enhancement to change them?
