Date in GL Account Posting ?

I am posting the GL a/c line items using BAPI_ACC_GL_Doc_post ...!!

In the flat file , i get the dates as '01/01/2006' and i convert it to 8 format by using :

split and concatenate .

The internal table (line_t) for line items has posting date as '01012006' , when i debug ...but then I keep on getting this error message : ' 20/06/0101 is incorrect in item 001...!! Though the line table has date has '01012006' , the BAPI returns this message ?

Can anyone tell what can be the issue ?
