We are interfacing detail data into the GL_Interface_table but the journal import process is summarizing the data when it gets to the ledger,. I have 69 lines in the file that we are loading all to the same codestring with different descriptions and the journal import process is creating a two line entry for this with the description of Journal Import created. However i need to have 68 lines with different descriptions same as file and than 1 line for the offset. I am sure i am missing a setup somwhere
