SAP B1 Mobile App no businesspartner data

Hallo,

i am new here and this is my first post. i hope sombody here can help me

I have a problem with SAP mobile app.

I managed to install and configure the app and nearly everything works fine

but i dont get any data when i klick on the BP module (i have full rights in the sap b1).

I can get to the BP information throught a sales quotation or a sales order tho.

I use a German Version on an Iphone 4 (ios 7.1.2) with the app version 1.11.2.

SQL server is 2014 Express and SAP V9.1 PL9
