i went thru the coding and understand that we need to do the changes in the

ME_READ_PO_FOR_PRINTING and ME_PRINT_PO function modules.

But i dont know how to and where to add my coding ( as above given reqmt) in those func.modules, also im not sure abt how to do the changes in the SAPSCRIPT FORM LAYOUT-(Desing/Text)</b>

Note:

For this, I had copied , MEDRUCK as ZMEDRUCK,

SAPFM06P as ZSAPFM06P ,

FM06PE02 as ZFM06PE02,

did the NACE part and configured the ME23N Print Preview with the newly copied programs and form.

copied...

ME_READ_PO_FOR_PRINTING as ZME_READ_PO_FOR_PRINTING,

ME_PRINT_PO as ZME_PRINT_PO.

<b>Also im getting a declaration related error when trying to activating the ZME_PRINT_PO.</b>
