BDC it 591

Dear Experts,

I have a requirement for BDC of Infotype 0591,

and I have done recording for it but the problem is that

when I open it0591 using pa30 there are 5 fields in it, but when i do recording or process the recording it shows only 3 fields,

i have tried using Table Controls but they also are not working in this bdc,

I think I will have to use HR INFOTYPE CREATION for this object but i dont know how to  use this fm,

please guide me and help me to complete this hinderance.

Warm Regards

Gaurav
