SAP Script - Open / write from from subroutine - via perform stmt

[former_member615325]

Please let me know if I can reference "open_form" and "write_form" function modules from subroutine. I have following code in the sapscript form.

/: perform hdr_text in the program zhdr_pgm

in the zhdr_pgm, I am calling the open_form and write_form to reference new text element that I created in the form.

zhdr_pgm.

form hdr_text.

CALL FUNCTION 'OPEN_FORM'

EXPORTING

form = 'ZPO_FORM'

EXCEPTIONS

canceled = 01

device = 02

OTHERS = 03.

CALL FUNCTION 'WRITE_FORM'

EXPORTING

element = 'TERMS'

function = 'SET'

type = 'BODY'

window = 'MAIN'

EXCEPTIONS

element = 1

function = 2

type = 3

unopened = 4

unstarted = 5

window = 6

bad_pageformat_for_print = 7

spool_error = 8

codepage = 9

OTHERS = 10.

Hi,

i have this same scenario. and in the thread was the answer "possible" or not "possible"?

to explain further here is my requirement

scenario:

dunning letter.

requriement:

when dunning rejected payment, we want to output all invoices related to it.

problem:

in f150 (dunning print program)

fetches all items for dunning

for each line item it calls the form to print each line (window main, text element 531)

now, for DD (rejected payments) from the script we can call a function pool to get all the invoices. but, how do we print these actually? can we from this function call write_form so that we can loop through each invoice items and print it?

Hi,

Instead of using the OPEN_FORM use the START_FORM & END_FORM function modules. Why because it is not possible to use OPEN_FORM FM again with out the CLOSE_FORM.

Hi,

it is not possible to call another SAp script form from one script form.

you cannot open one form inside another form, it will never work because I have checked that.

So you are the "last instance" of SAP-SCRIPT knowledge? sorry just kidding, but it read a bit like this :).

You could however, store the information you wish to print on "second level" in an itab and then when you first form is ready process these stored "forms".

[Former Member]

what is your exact requirement?

what do you mean by "to reference new text element that I created in the form"??

[Former Member]

Yes - it's bound to be easier to simply create a text and include it.

Well, since you already have a form open (your SAPScript form), I don't think trying to call OPEN_FORM again is going to work.

Rob..Thank you!, do you think, just write_form is going to work, if I remove call to open_form, please let me know.

[Former Member]

It seems awkward, but I guess all you can do is try it.

I guess it won't work. you are trying to write one form while you have another open.

I dont really see a benefit with this solution, just problems.

Would you mind to tell us what brings you to the diea? what is your exact requirement, maybe we can propose something else which will fulfill your task as well.

E.G. like rob already proposed, building a text saving it useing SAVE_TEXT and inculding it.

Thank you Rob, Patrik and Florian, thank you for your input. required design is to loop through the elements on the form and print text, we are still working on it and will keep you posted.

I would still ask you to explain to us in brief your total requiremnt
