📊 Remove special character in BW transformation
Welcome at github BW tool for remove special characters, fell free to contribute and create pull requests.
If you have frequent data load from flat files in your BW, you know that user can provide wrong characters into. To prevent activation error of this data, please use this development in your transformation end routine on the first layer (RSDS->DSO).
No all special characters defined in BW can be hanlded by infoobjects. Due to that, if user provide unexpected chart, we get an issue in case of data activation in our BW system:
or other informations like:
This development check infoobject based on passed reference table. Best idea is to use this in end routine between flatfile source system and target DSO. You can't use this if your target object is field based instead of inffobect based. If any invaild characters occurs, it will be automatically replaced by nothig ( cuted off).
This development uses standard SAP function module RSKC_CHAVL_OF_IOBJ_CHECK, which basically checks every character you are trying to pass to particular infoobject and confirms is that character allowed to be used in. Most of avaible implementations check correctness of passed characters based on SAP note 173241:
!"%&''()*+,-./:;<=>?_0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ
This implementation addiotionaly:
DATA(lobj_check) = NEW zcl_bw_validate_special(
ir_ref = REF #( result_package ) ).
lobj_check->validate(
EXPORTING
it_tab = result_package
it_monitor = monitor
IMPORTING
et_tab = result_package
et_monitor = monitor ).
