Need to print multiple distribution lines for a ap invoice line in the pre-printed check stationary

Hi,

I have a client requirment to print all the distribution lines for a ap inovice line. for example for invoice line 1, if i have 3 distribution lines, i need to display those 3 lines in the pre-printed stationary.

i am customizing the below pkg to display all the distribution lines for that invoice.

Issue is: after running the check payment process in AP. the xml tags are generating only for one distribution line.. not all distribution lines. 

can anyone having the sample script to display multiple distribution lines for check printing.

pkg name:IBY_FD_EXTRACT_EXT_PUB,

in the xml tags that are generated in the below table showing only one distribution line.
