Now,
When we have made SQVI working, we'll look into your Original requirement. That is to Input BOM component material(IDNRK) in Selection screen and get BOM number (STLNR).
System has given you 4 fields in selection screen namely STKOB-DATUB, MASTB-MATNR, MASTB-STLAN, MASTB-WERKS. You just add STPOB-IDNRK like below
Also you should have your required field BOM number (STLNR) in the List fields
With this you will find a separate Block in selection screen names Program selections where your BOM component number field is there. Now you are required to fill both the fields MATNR and IDNRK in the selection screen to run your report for quick response. If you fill only IDNRK field and run it might take 5min to give you output.
