Solman 7.1 SP7 finding sold-to party when creating a new ZMIN

Hello experts,

Hi, I am configuring service desk in Solution Manager 7.1 SP7. When a user creats a new inicdent (ZMIN) he has to fill the field "sold-to party". This field is empty by default. Why? Because the IBase is empty too and in SPRO "Define Partner Determination Procedure" finding "sold-to party" is defined with parameter "Preceding Document --> SAP Service: Determination via IBase/ind. Object from Ref". So, no IBase no "sold-to party".

In Solution Manager 7.0 EHP1 this construct works very well, because when setting the userparameters IBC and IIB a new incident (ZLFN) always uses this values as default IBase.

In Solution Manager 7.1 this userparameters are not working anymore. .

Is it possible to set a default "sold-to party" value, when a user creats a new ZMIN-Incident? Or is it possible to set a default IBase value?

thx for help!
