Problems to install SAP_BS_FND 747

Hello,

we have installed SAP NW SR2 Abab Server.

Also installed is WEBCUIF 747 in this system.

Now we want to install SAP_BS_FND 747

But in the SAINT we get this error:

WEBCUIF,731 Component must be installed in this version Precondition is not fulfilled Non-permitted release of add-on WEBCUIF installed

So what can we do?

Gruß

Toni
