Function module MB_CREATE_GOODS_MOVEMENT cannot be executed

Hello Friends,

I am invoking following 2 BAPI's from MII one after another.

1) BAPI_GOODSMVT_CREATE

2) BAPI_REPMANCONF_CREATE_MTS

First BAPI is getting executed successfully and it creates the Mat document number as well. But while calling second BAPI I am getting an error as "Function module MB_CREATE_GOODS_MOVEMENT cannot be executed".

Can anyone help me on this? I think both BAPI should execute in same transaction session to complete the transaction successfully at SAP.

MII Version 15.1 SP5

Thanks
