Function module called within a loop seems to carry over global data

Former Member — Thu, 15 Sep 2011 20:11:16 GMT

Hello all,

I am calling FM "RS_COVERPAGE_SELECTIONS" inside of a loop of all variants for a program and then writing the variant values to spool. If only one variant is entered on the selection screen, all the values are correct. If nothing is entered, some of the variant values are carried over from a previous variant. I am emptying the internal table returned by the FM every time before the FM executes.

Would some one be willing to run the following code for a program with many screen fields and many variants and tell me if they get the same behavior?

Thanks

Bruce

If you debug the FM, you'll see that after each time the FM is executed, the internal tables contain the data from the previous run(s). I was surprised when I furst noticed this, but it is standard FM behavior. You may be able to find a FM (but it has to be in the same group) that clears global memory. If there is one, you can run it before each run of your main FM.

Try using the function module PRINT_SELECTIONS, within this FM, the FM RS_COVERPAGE_SELECTIONS is being called. So it will not copy the previous values.

Pass Mode as 'A' , report name and variant name, then it will display the same output.

Please try it
