Can't define Branch while create SO from SAPB1 Mobile

Dear Expert,

I try to create a Document SQ and SO from SAPB1 Mobile apps, but the Branch field is disable to define (there is no drop down list). I already setup the Default of Branch Assignment on my Super User Account and on BP Master data Setup.

Already reference to SAP Notes 2351736 - Branch Is Not Supported on SAP Business One Sales App, but I already using more higher version of SAP B1.

Did I miss something when setup the mobile apps ? Please let me know.

I'm Using SAP 9.3 PL 7 Hana Version.

Kind regards
