CALLING BDC IN WORKFLOW

Question

HI
I am trying to call a bdc in my workflow based on the user decission i.e. after user makes a particular decission it has to call BDC. I am using a call transaction statment for calling my BDC, I have defined a FM for the same the code i have written is : call transaction 'zapprove'  after this i have made a business object based on this and defined the task. I am calling the task after the user decission in order to run the BDC but it is not updating the required table. I have checked the BDC as well as FM and BO all of them are working fine so i am not able to find the particular error. Please help me on this.
thanks in advance.
