Changing parameter value is not passing to form

[Former Member]

Dear Experts,

I have called a perform cmmand from a SAPScript passing two variable dateparameters one as using parameter and another as changing parameter.My logic is like that when changing parameter is blank it should feel with in the form but if not initial it should come as it is before.While i test passing the changing parameter as filled it shows the value in sap script but when i call ther form the value field goes empty.

the changing parameter is more like an EXPORTING parameter, any value in it is not taken from outside : it can be only filled inside your routine

it is disturbing that we call it a CHANGING parameters as it is not really one

Hi friend

I am not clear about ur reply...then how can i get the calculated new value(which is been calculated with in the form) back to the SAP Script?Pls suggest a way so that i can calculate the value with in the for and can display it ti sap script.

On your entry into your subroutine, the output side table will be initial, so all that stuff isn't needed... read your input table INDEX 1. Get your date from VALUE. Do your calculations. Read output table index 1. Insert the date into output-value. modify the output index 1.

Most of us would probably also declare a variable with /: define &mydate& = ' ', and change that with the perform routine, then use that in our SAPScript output.

From re-reading your post, it appears that you need two parameters in USING, and one in changing....therefore, change it to using both dates and changing one date...one date will be in your input table-VALUE index 1, the other in VALUE index 2. Your changing will go into the output-value index 1.
