DYNP_VALUES_READ Limitations for multiple lines select options

Question

Hi all !
   First post here, but a tough one I think. Here is my inquiry :
   I have worked on an specific abap function used in many long abap list reports. Theses reports are launched in background processing. The aim of this routine is to stop the report execution if a background job with the same selection parameters is already launched for the current user (to Prevent useless several launch of a time-expensive program).
    Because this routine is dynamic, I read the selection screen of the current report with the function 'DYNP_VALUES_READ'. And I compare the result with the variant of the backgroung job (read with function 'RS_VARIANT_CONTENTS').
    The real problem is that function "DYNP_VALUES_READ" only extract the first line of select-options. I found an alternative solution to extract the select options values (a dynamic assign with field symbols), but external conversions (for WBS elements for example ) are lost, so the comparison detects differences between the background job's variant values and the current selection screen values.
    Does anybody know a way to get entire select options values from a selection screen just as they are displayed on screen ?
Thanks for reading my message

Thomas,
Perhaps the following code will help you.  A function module in the code captures everything on the selection screen into an internal table.  It doesn't actually capture the information the way you want it, but I believe you will be able to work with it to achieve your desired result.  If it doesn't meet your needs, it is still useful for printing selection screen fields and their values.
