Answer 1

hi
Please ask question on sapscript in sapscript forum.
use sap script form  medruck for PO
SmartForm /BPR3PF/MMPO_L is the standard delivered Purchase Order in 4.6c
Transaction code m/34 allows you to associate your 'Y' copy of the standad PO to your included company specific PO requirements such as company log graphic and other particulars.
Go to transaction OMFE. Tell me what you see there for the output type you are interested in. Let me take the standard output type NEU. The entry looks something like this.
NEU Purchase order 1 SAPFM06P ENTRY_NEU MEDRUCK.
The first one is your output type, next is its description, next is the medium, then the program, routine, and the form name.
You already copied the layout MEDRUCK to ZMEDRUCK. Now copy SAPFM06P to ZZSAPFM06P. Now ENTRY_NEU routine is in the include FM06PE02. You need to make your changes here to accommodate for the new field. So copy this include to ZZFM06PE02 and make your changes. Also, in ZZSAPFM06P, change the line where it says INCLUDE FM06PE02 to INCLUDE ZZFM06PE02.
Now in this routine ENTRY_NEU, there is a function module call ME_READ_PO_FOR_PRINTING which reads in the PO data from the tables. We need to copy this function module as well as this is where you will do your extra selections for the new fields. You will do the same with the other function call ME_PRINT_PO, if you need to change anything on the print.
after this to define output type...
NACE
You can track the form and the print program used for that form
NACE is used to create output type while creating the output type you will mention forms, and driver program.
that will be maintained in the table TNAPR.if you create the output type using NACE then it will be automatically visible in table NAST and TNAPR.
so check in NAST, TNAPR table

Condition records in NACE?
EX--in simple terms..take a transaction say ME21N ( Purchase Order ), u can see a Print icon there. now when u click on this icon, it has to print the PO document. Now how does it do that? when u click Print, the control gets transffered to a print program, now which program gets triggered is decided by what program name u specify in NACE.
So in NACE>EF>Output Type>NEU>processing routine--> u can see some standard program already configured( maybe SAPFM06P n form MEDRUCK )..these are the programs n sapscript that gets executed wen u say "PRINT" in the transactrion...so u can customise the print program for customer changes over here by copying the standard program n form into a Z/Y one and replacing the program names in NACE.
